I thought it might be interesting to discuss our upcoming theater project. We are custom building line array speakers for all 7 channels. I am sure some controversy will occur over the center and rear speakers. We are going to install them horizontally. The length of the center will be almost as wide as the viewing area.
We have all the cabinets built. A Couple of pics are included. The cabinets shown with drivers installed are the side channels.
We are integrating custom built Class D ampliers (2 two hundred watt amps per speaker) with built in electronic crossover as well. Going to test out our prototype version tomorrow sometime.
The room is 25 by 16 by 10. Woofers are still in discussion,but I was thinking about a couple Exodus Audio's new 21" woofers for the front and some built in Wisdom inwall woofers for the back of the room.
Should be a fun project!

Ddingle - have you heard the Wisdom S90I in action yet? I was at the factory a couple of weeks ago and was simply blown away by the depth and tunefulness of the unit. They have the option of using up to 4 in their demo room.

Also have to ask if you didn't consider the L150I for this rather than building your own huge custom line array with conventional drivers?

I have heard the S90I at CEDIA last year. Unfortunately not critical listening in the cardboard room they were demonstrating in. The size works out nicely in the back of the room or even built in to the floor risers.I like the Wisdom team. They know what they are doing.

These custom built Line Arrays should offer more bang for the buck than any ready made product.Hopefully!

The right and left are going to be floor to ceiling!Around 9 feet. Ideal for Line Arrays. Sensitivity should be in the 95db area.

With so many drivers,it takes very little motion from each to produce high levels.Distortion is very low. Dynamic Range is off the charts high as well.

We also have the option of modifying the speakers if things don't work as well as planned.I do not expect that to happen however. I have a feeling there will be few home theaters with this many drivers in it. Although we are not looking to win any contests ;)
.

Are they going behind a screen?

Are they going behind a screen?

No,After much discussion we decided to go with a Solid Screen. It is a Stewart Studiotech 130.Constant Area Design. 60" by 144" 2.40 aspect and 70" by 125" for 1.78
The right and left speakers fit just to the outside of the screen. The full length center channel is above the screen.As it is a line array placed horizontally,it should have good vertical dispersion from it's higher than desirable position.Being the full width of the screen should allow for good horizontal center channel coverage.It has a "tapered" output,the outer drivers are at a lower level than the middle ones.
At least thats the idea.We're working with a engineer who knows line arrays in and out.
The customer did not want to compromise video. That is his priority.
The projector is a DPI Reference 3D.One highlight is a Intelligent Lens system with memories for zoom and focus. No anamorphic lens required.
I do not think the audio will be compromised a ton by not being behind the screen in this case. I will post some more pictures of the speakers in the near future.

It sounds like it is going to be a very cool ht room.

I had some decent line arrays in my old theater and must say it was incredibly impressive sounding. I still miss the line array system when I listen to music.

While I haven't done any of the math on it, I would guess your center channel is a wider array than you need and I would try to stick to vertical arrays for surrounds and narrow down the center array a bit to steer the center channel towards the center more for older soundtracks that were mixed correctly. Lots if not most of the newer releases seem like they have totally screwed the pooch on keeping dialog in the center channel.

I agree with Mr. Poindexter about the center. Remember how the center is mixed. Nailing the center in the center is crutial for the people listening off to the left or right. A full width center will blur pans and dialogue. Consider the distance between either front speaker and the center. It may be only a couple of feet if your center is a full width horizontal line array. It would be much like setting the fronts to "Large" and crossing over the center at, say, 120Hz with a single center speaker. Everything from 120 down would go to the left and right fronts, blurring the center and increasing its apparent width. That example assumes a bass management system that allows for that. I have line array front left and right with a single surround in the center. The front left and right should be out from the back wall and the side wall too. My surrounds and center are the same speaker, the fronts are line array.

Thanks for the input!
We are "tapering" the output of the center channel away from the center of the speaker.
This is a bit of an experiment, so we can even disable drivers if it seems appropriate. System should be complete late this fall sometime.

I suppose if you wanted to stick with the massive number of drivers, you could experiment with a highly convex enclosure and simulate a point source but I am not really sure how that would turn out acoustically.

a horizontal line array will produce one big vertical lobe in the middle of the room with wicked fast fall off as you go off axis. a steerable lobe (from left to right) based on DSP products used to be sure, but a nice thin vertical lobe.

Here are the woofers we are using in the front. 4 Exodus Audio 21" drivers.
2 woofers per 2' by 2' by 5' cabinet. We are also going to place 4 of the new BG in wall woofer design in the sides and rear of the room. See review for more info on those.

http://www.hemagazine.com/BG_Radia_BGX-4850_Review

In addition we tested the prototype custom amplifier design for the arrays. 2 Hypex UCD 400 HG HXR modules combined with a Marchand XM44 crossover in a single case. One of these for each speaker. So 7 for this system.
As an experiment we upgraded 4 op-amps in the Marchand to a more "audiophile" design.Early listening tests produced good results!

Interesting thread. I normally hang out in the DIY section but I'm going to post here so I can track this amazing build.

We are using a Minneapolis based driver supplier! Misco has been in business for something like 50 years.

Still working away on this project. Here is a quick photo of one of the front left and right speakers. 8.5 feet tall!
Should have them in a test mode this weekend.

What drivers are you going to be using for the arrays?

I would also like to know the drivers being used.

Absolutely insane, well done! :) I'd love to hear how they sound.

I've used lots of Misco speakers, but in a different application. They make great weatherproof speakers, and I used their 4" in 100s of drivethrough intercom systems at McDonald's.

I would also like to know the drivers being used.

I recall they are a special order from Misco. I did not place the order,but will see if I can find out what the model or part numbers are.

Everyone was anxious to hear the big arrays. We set them up very roughly with the custom Class D amplifier/crossovers at the office. Pretty outrageous sound! Did not even make any level adjustments on the woofer/tweeter controls. Seems pretty balanced. Listening to familiar recordings, it seems more like the instruments are "in the room".As big as the speakers are they "disappear" nicely.
Fine tuning to continue.

Tried the newly remastered Beatles recordings. It really sounded like John Lennon was alive and well between the speakers!
Lifelike imaging would be a major understatement.

Congrats I think I can imagine a phenomenal sound stage.

The project is in a bit of a hurry up mode.We are not going to have time to really tweak anything with the crossovers before we install them on site. Not a big deal it seems pretty close right now. There will be plenty of testing and adjustment after installation

Since I have the 2 front channel Arrays set up, I decided to experiment with Audyssey MultiEQ pro. We have a T785 NAD receiver with the latest Audyssey card installed. Brady quick installed one of the 21" woofers to go with the arrays. Set it up as a stereo with sub arrangement in the Audyssey 3.2 software. Used 12 positions with the pro microphone kit.

I like the NAD (Paul Barton from PSB designed ) curve. Quite a bit more musical than the Audyssey or Flat settings.

First impressions are EXTREMELY favorable. I am hearing things in extremely familiar recordings never noticed before. The dynamic range is unbelievable too. Classical music has never sounded better to me. The William Tell Overture (Telarc) Rocks ;)

I am sure there are better Eq systems than Audyssey,especially when at this price point,but I could EASILY live with the results I am getting.

I have not picked a processor yet,but the NAD M15 HD Master Series is a prime candidate.Add the separate extra resolution Audyssey EQ for woofers and it might put us where we want to be with this system.

More listening this weekend. I keep my Audio Control RTA in the room reading the max decibels. It is easy to get out of hand.

So better than the Cinepro? (Inside joke).

The Cinepros sounded great! I know we were warned at the CEDIA demo,but used earplugs for most of it. I might be showing my age :)

As this post is in the high end forum I would suggest the McIntosh Labs new MX150 pre/pro as your processor. The MX150 has 12 channels of outputs and each channel has a separate "RoomPerfect" processor. The “RoomPerfect” processors are designed by Lyngdorf and in my experience the RoomPerfect processing works great. I have the Lyngdorf TDAI-2200 integrated amplifier driving a line source speaker I built that has the Bohlender Graebener RD75 75” planer magnetic and 4 Dynaudio 6.5” midbass drivers per cabinet. I have used a number of electronic x-overs, DSP devices and amplifiers to drive the system but the best the system has sounded is with the TDAI-2200 setup using the internal x-over set at 300Hz and the TDAI-2200 amp running the RD75s with a McIntosh MC402 driving the Dynaudio midbasses. The RoomPerfect processing out preformed any combination I could come up with x-overs and DSP and the setup was 15 minutes with RoomPerfect not 15 hours with DSP. I would imagine 12 channels of RoomPerfect would drive this system to its full potential and although the MX150 is very expensive the other option might be an 8 channel Audyssey Sound Equalizer and a couple of Audyssey Sub EQs in addition to a Pre/Pro.

Has anyone heard the MX150 yet? I recall Lyngdorf and Triad were going to distribute a multi channel correction system last year but decided it against it.

We are using a roughly 8 foot version of the line arrays for the theater side channels. Normally with a dedicated theater we place the side speakers facing the primary or "money" chairs. There are 2 rows of seating with the 2nd row being the primary.
It has been suggested with the super wide horizontal dispersion of the arrays we should place them exactly between the 2 rows. This would allow for both rows to receive maximum coverage.
Any thoughts on this? Not too many systems have lines in the sides.
Thanks

Thomas,

I sent you a PM

Probably a dumb question but how does a single 21 inch woofer "keep up with" a "gaggle" of mid-range drivers and tweeters. I'm thinking of cone movement/acceleration/speed. I know there are huge motors with these larger woofers but it still seems to me that you can't fool mother nature.

The reason I ask is that my only experience with large line arrays and HUGE subs that I heard in five different venues was highly rated by TAS (and others) but cannot remember the name. NO matter where I heard that system (two CES's/multiple rooms and a private home owner), the integration of the bass to the towers was just awful. The suckers were also incredibly expensive. Harry Pearson of the Absolute Sound thought they were amazing. I thought they were amazingly bad.

That said, there is a guy who posts on another forum who has a friend who has that speaker BUT with with (a) a Tact 2.2X room correction system and maybe more importantly (b) he is using JL Audio Fathom Subs (the manufacturer supplied subs were 18 inchers).

Comments?

We are using 4 of the 21" woofers in this system. 2 cabinets with 2 of the woofers in each cabinet.
In my testing so far a single 21" sounds quite integrated with the line arrays. Audyssey EQ in this situation helps for sure.

how does a bass drum keep up with a snare? a bass guitar with a flute...

the sound waves are inherently different, so their behavior is different

My point exactly. Most systems that I quickly recall with large woofers (e.g. the large Wilsons or Dunlavys) transition up through larger and larger drivers as opposed to going from a 6 inch midrange driver to 21 inch bass driver. I can't image how they would integrate correctly, no matter how many 21 inch drivers you use.

The Dunlavy VI which was a four way system with a 15 inch woofer had an 8 or 10 inch mid bass, then the midrange, then the tweeter. The Wilson X- Series takes a similar route.

Help me out here. (By the way. I talking about two channel audio and not home theater)

all i can really say is that a line array does not behave as a small driver. it acts much differently. since if you really do build a line array and not a long line of drivers (correct acoustic spacing) it behaves more like a fast responding large driver.

We found a way to put the side arrays just slightly behind the "primary" row of seats. Not quite 110 degrees specified for sides,but pretty close. The front row will still be exposed to these,but,the delay/timing will be off somewhat.
Seems like a good compromise.

The crossover to the woofers will be 80hz to 100hz. The arrays easily cover above that. I set it for 80hz during testing.No complaints! The mid drivers in this design are really good. 22 of them per channel allows for terrific power handling and lower bass extension.
Actually there have been several successful line array designs with 18" woofers.

I wonder what the frequency response is with all those drivers. It must get pretty low on its own, right?

I recall the generally maligned Bose 901 producing half way decent full range sound from nine 4.5" drivers.
So with 22 it could easily go lower than the 80hz I am crossing over at. I am not expert in this regard,but limiting the high pass to the arrays keeps intermodulation distortion to the midrange frequencies from occurring during bass passages.More of a concern than bass handling perhaps
Audyssey thought the crossover to the arrays should be 60hz as I recall.

I recall the generally maligned Bose 901 producing half way decent full range sound from nine 4.5" drivers.


Yes, but the high power midrange speakers were REALLY equalized. Figure a 'happy face' eq curve on a 10 band eq and then some. From what I remember, the bass and treble boost was in excess of 16 db at some frequencies.

Keep doing what you're doing.... I for one am fascinated. :)

All the speakers are now at the job site. Progress on the theater has been slow. Permits for a sprinkler change or something.I will post some more pictures later.

Never too late for a last minute PJ change.

Sorry Peter,but the DPI Titan Reference 700 3D is also on site. Won't be able to access first run movies available with the Barco.
Our client does own 1000s of DVDs and most every Bluray released so far. Plenty to watch.

I was just joking of course, but when I decided to do the CEDIA thing is based on the fact that the modded DCI projectors I consider as a better solution fro Blu Ray, no doubt. For DVD? well very few dvd's cut it, 5 in 100 are worthy of very large screen viewing.

So the reason for DCI PJ's is NOT DCI content, in my opinion.

A bit off topic,but I wonder if there will be a satellite or internet derived service providing Bluray quality downloads at some point. Not first run,but release dates similar to DVD/Bluray.
Vudu's better HD downloads are not bad,but not quite Bluray.It would be nice to have the Dolby HD too.
Just dreaming

This project is super slow. It seems like the contractors are stretching things out.Hoping the economy picks up before this project ends. In the mean time Brady built a set for himself. Similar to the LRs in the proposed theater.
Brady uses 4 18" woofers in an infinite baffle for the bass. Still tweaking,but the sound is addicting to say the least.

We have set up the LRs for the theater in another completed part of the house. We recently converted all our clients CDs to a Sooloos media server. 14700 cds!
He is having fun searching through the collection I did a quick Audyssey EQ on the temporary Line Array set up. I am really liking the results!
Hopefully it wont be long and I will have a few pics of the installation.

I love the fact that the kid gate is keeping them IN with the equipment and speakers! :D

We custom built similar Arrays in a 5 channel arrangement for another area in the home.Just have 2 channels up so far,but they really fill the room with sound!
Only could convince the designers to integrate 2 of the BG Radia in wall woofers,but my initial impression they should be adequate.
March is going to be the month for the theater!

Interesting design and well implemented... fantastic looking house btw... WOW

Acoustic treatment in there would certainly come to mind on first glance... Look like it would be quite an echo chamber with all the hard surfaces...

Thanks for posting pics - looks great...

Thanks! No chance for acoustic treatment in the pictured environment :(
Our speaker guru feels the Arrays have a advantage in a poor room like this.Their directional behavior will not "light" up the room quite as much as other designs.
Our initial impressions are confirming that to be the case.
The theater is another story. We will have plenty of treatment in there!
I just heard the deadline for completion of the theater is now April 18th
Looking forward to testing both areas out!

The theater is just starting to take shape. We installed the Stewart "Director's Choice" Frame and testing the fit of the amplifier racks behind the screen.
Green Glue City on all surfaces.
More pictures as we go forward next week.

Still Working on this forever project ;) Here are a couple of shots of the 21" woofers and side channels.
One picture is of the Isky star ceiling system getting started.
Taking a week off to let the contractors catch up with lighting etc.

Progress! Our client is watching movies and satellite in his new theater.Just starting to calibrate.The DPI Reference Projector is almost worth the money! Better than a movie theater comes to mind. The line arrays are barely installed and still give a worthy presentation.Going back in mid June for full calibration. Here are a few pics

Do the racks have the Sony Blu-Ray Disc changers in them?

P.S. Nice job. Keep posting pictures. :)

Thanks! The room is too dark for decent pictures. Next trip we will bring in lighting to get better results.
Yes those are Bluray changers! Since the Media server copyright issues have not been resolved we are going the changer route for the foreseeable future. AMX and Sony are working on a control for multiple changers. The changers can access Gracenote and organize the Blurays or DVDs into Genres etc.
Actually there is another small rack behind the screen with the theater amps.
The pictured rack is in the adjoining room. Also includes whole house equipment.

Nice, hey I notice the downlights have a shroud/extension on them, is this indeed a light can extension? I assume to travel the distance of the acoustical ceiling.

What make?

Keep up the good work.

Yep! This guy can fill rooms with movie/music software in short order. We still want to do something with his massive DVD collection,but since Kaleidescape cant effectively handle the size of this collection and everyone else seems to be using offshore software for ripping,we are holding off.
Sony had a nice setup for IP control (400 disc Bluray changers) with AMX systems,but they soon found out the update compromised their Gracenote access. We are waiting for a fix. The changers should be a good compromise for now. A bunch of them costs a tiny fraction of a decent sized K system.

Hi Peter! Thanks. I am not sure of the manufacturer.Nate my partner and lead project manager should know.As soon as I find out I will add it to this thread

I have known this client for many years. While installing an antenna at his home in the early 1980s, even back then we found stacks of Laserdiscs stored in closets,behind furnitureetc.
LPs as well. Probably not the largest collection of software in the world,but in the top 10 percent :)

Top 10%? I would venture it is more likely in the top 0.1% and might have several more leading zeros if you do not count business owners of rental shops (although it sounds like he owns more than most of them, too).

Found a couple of additional theater pictures. One of two IAC doors, Twins Game 1.78 image.Theater seating.
The IACs work! Really isolates both areas.

Continuing progress. No additional pictures at this time. I had success in equalizing the bass. Utilizing the Audyssey Sub EQ.
It seems the Hypex amp I am using for the 21" Woofers needs more input than average to produce the "reference" level Audyssey recommends. The in wall BGs were easy to match to the reference which is part of the Sub EQ initial set up.
I did about 15 measurements around the "primary" seating area with the Sub EQ.
Since the NAD M15HD has built in Audyssey processing as well, I tried the recommmended 7 channel procedure when using both a Sub EQ and a 7 channel Audyssey. Basically place the mic in the exact same places for both sets of measurements. I did not like the results with the 2 Audyssey processors in place together,so experimented with the Sub EQ only. Even with the woofer level maxxed out on the NAD, I felt the bass levels were low. So I lowered the other 7 channels by 4DB and left the woofer output at maximum. Bingo!! The Audyssey Dynamic EQ in the NAD was also fooled into a little more bass emphasis in general. The overall effect is pretty fantastic.After playing with audio equipment for several decades, I believe a first ever occurred.
Playing this recording

http://www.amazon.com/Pomp-Pipes-Dallas-Wind-Symphony/dp/B00000159M

My hair moved!! Below 20hz for sure on the Organ in this recording. Wow.
We have the projector mounted in a soffit at the back of the room. Some of the deeper bass seem to be moving the projector or the wall it is attached to!
Going to have to strengthen that in some way.
The Line Arrays sound great! Even without EQ.
Our client brought his pristine Sheffield Vinyl,these Direct to Disc recordings from the 70s sounded more like the instruments than anything in memory.
I calibrated the DPI and Lumagen together for the first time. Is there a better combination? Not sure,but the video is fabulous.
I'll get some additional lighting in the theater next time and take some decent photos.

Starting to have some fun!!

Not having much time to take decent pictures.Mostly working on getting things fine tuned. The Audyssey Sub EQ and NAD M15HD with Audyssey worked as advertised. I took measurements at different heights to get a better "picture" of the arrays. Overall the sound is flabbergasting! The Doors "Riders in the Storm" sounded better than I have ever heard it. The DPI looks unreal as well. This picture is about as good as I could get for now.

The client and the Architects agreed on exposing the Line Arrays without grills! The rear channels have GOM fabric over them and it was easily noticed as a loss of high frequency.Audyssey Equalization mostly corrected for the loss however.

It seems we are close to achieving audiophile detail and resolution for music with bone crushing high output capabilities for Movies. Yeah!

Imaging seems really good too,but I found that reclining all the chairs improved it.It is really a 2 "Money Chair" theater. You have to sit there to really get the results we were after.

When listening to music we tried Dolby Pro Logic 2x Music mode. Very effective. Panarama option from Dolby set to on.
Having all the speakers in play makes for very dynamic results. All our techs enjoyed surfing through our clients "Sooloos" server to listen to their favorite material. Everything sounds great!

The earlier discussed horizontally oriented Line Array center channel is pretty directional left to right,but not enough to effect the primary seating areas.The center image seems locked in the middle.The output is tapered lower from the center to either outside edge of the center speaker. When using the Dolby Prologic 2x Music mode the results sound like no speakers at all. Audyssey probably helps with the timbre match.


The detail from the center is pretty amazing too.It was easy to hear the difference in the acoustics when the Minnesota Twins announcers moved from Baltimore to Kansas City one night to the next.

Pans from left to right do move towards the top of the screen and then down again,but I had to use audio test patterns to notice it.

Joe Kane's Bluray test disc has a nice example of pink noise pans through all 7 channels
More testing and experimenting to go.Taking a break to let the client mess around and provide us more feedback as to his preferences.

A side note: The Sooloos Media Server can be controlled by an Ipad! Easy to use anywhere on the network. This proved fortunate since AMX has not completed a Module allowing their system to control the Sooloos.
15000 CDs on the server! You can add Hi Rez music on Sooloos too. Not cheap but seems worth it. Here is a picture with the Control 10 Sooloos in front of the Family Room in wall Line Arrays

15 Thousand CDs? Wow!!

15 Thousand CDs? Wow!!

Ok,14,700 and counting ;)
Having a very high level of reproduction mixed with a extremely wide selection of material makes for long fun hours of listening!
