JackO's Media Room

post #1 of 38

Thread Starter 
Completely sealed speaker configuration in a 6000 cu ft irregularly shaped enclosed room with 15' ceiling. 100% Home Theater use.

Equipment
Display: 60" LG Plasma 60PZ550
AVR: Yamaha RX-A3000
Amplifiers: Outlaw Monoblock 2200 x 3 (L/C/R)
Cable/SAT: DirecTV HR21-200
Blu-Ray Player: Panasonic DMP-BD45
Gaming: Xbox 360 w/ HD-DVD Player & Kinect

Speakers
Left/Right/Center: Elan Theaterpoint THP650LS
Surrounds (4): Elan Theaterpoint THP650SS
Subs: HSU ULS-15 DualDrive, Elan THP1200SW x 2

Memorabilia
Goodfellas poster signed by DeNiro, Pesci, Liotta and Scorsese
Tony Hawk signed skateboard
Fran Tarkenton signed jersey
Gilbert Arenas signed jersey
Cris Carter signed picture
Nolan Ryan signed picture (of him working Robin Ventura)

What's right about the room
Surround sounds great, Elan Theaterpoint speakers sound amazing pushed by the RX-A3000. Black out shades. Mini-bar. ULS-15 x 2 shakes HARD. Earthquake hard.

What's wrong with the room other than the dimensions
Rears are dipole speakers... not perfect, but I didn't want a speaker sitting 17" out of the wall at shoulder height. Rears are also so close to each other that it's really a 6.1 system.

What's on the horizon
I've got 2 more THP650LS's in boxes, but the front stage has little room for height presence speakers. Not sure how to get them wide of the L/R channels.

Hello JackOften, Welcome to the WYSC family.

I think we need to talk some more about your system and the room. So if you want, call me again sometime today. I have your AVR manual on my PC now.

Awkwardly shaped rooms are always hard. My current apartment has a really weird shape with several angled walls. Because of the arrangement my rear speakers are about 10-12 feet off the ground, my left and right speakers are under the screen cause I can't space anything out, and my seating arrangements are severely limited. You definitely have a decent setup giving the triangular room.

HTG put me on to a nearfield midbass subwoofer. Suddenly it doesn't look so bad. Time to find some cash...

When you get a chance could you post updated pictures with the new subwoofer placements?

I read your PM and wanted to let you know that I was glad to be of some help with tweaking your system. So have you had any of these or any of with the new setup?

Will do this weekend. Pete should look at employing you as tech support btw. Talk about passion meeting expertise.

Just gotta find a used ULS-15 and a MBM-12 to round this baby out!

That couch is a semi-disaster, but i'm not sure what else would have worked. The back supports are movable with rubber bottoms. Works for smaller people but at 240 lbs i find myself moving them back in to position half-a-dozen times during a movie or else they gradually fall off the back of the couch.

Yo HTG

I'm going to try the Elan sub in place of the Infinity IL120 this weekend. I think that change I was hearing was the 'fatness' of the IL120 that fell off (loose/ported is what i mean) vs. the cleaner sealed Hsu.

Quick Comparison Table:
Code:
Sub               Size     Amp    Cabinet Size  Weight  Freq Range  Type
-------------------------------------------------------------------------
Infinity IL120    12"     500w    5962 cu in    45 lbs   28-150     Ported
Elan THP1200SW    12"     300w    4752 cu in    37 lbs   22-150     Sealed
HSU MBM-12 Mk2    12"     350w    4788 cu in    47 lbs   50-150     Both
Through the MBM-12 in there for comparison, It's what really needs to go in there.

Elan THP1200SW

Just for an experiment place the ULS-15 right in front of the bar, where the trash can is, facing the same direction. You might get a couple more Dbs with corner loading the ULS-15.

I'll try that, good idea. Bonus: it exposes less of the wiring.

Yo HTG,

I'm going to hold off moving it. Got a 2nd ULS coming in. I've attached a location i'd like to throw it, any thoughts? Good spot? I'll measure it out to they are equidistant from the primary listening position.

Are you planing on keeping the Elan THP1200SW in the mix?

Right now i've got the Infinity IL120s in there .. I was going to experiment with taking it out and/or swapping it with the elan once the other ULS gets here. When i've used the Elan in the past 300 watts in a sealed enclosure doesn't seem to get much done. Any thoughts?

Well I do not believe you will need the Elan Sub. I would approach the intergration of the second ULS by leaving the first one where it is now presently located.

First, you would go through the process of gain matching the two ULS-15s. The first one has already be done, so place the new one in the same location you place the first one, when we did this process a couple of weeks ago, and adjust the gain on the new one, using your SPL meter at the same place you had it when you measured the first one so it also is playing the same dB as the first one.

Now using the wireless feature on the second new ULS, BTW congrats, I would place it first by the fireplace and play some heavy bass content, walk around the room and see how it sounds, again listening for the tightest smoothest bass. Then repostition the sub to the corner where the Elan is and again listen and see if there is an improvement. We also talked about co-locating both subs below the TV so this would be a third option to placement in your room. So bottom line you have some work to do next weekend, or sometimes, you can spread out this process over several weekends. IOW place the second one by the fireplace watch some movies and listen to some music. Then the second weekend move it to the right rear corner and so on.

But as you know everytime you repostition the subs you will need to run Audyssey, one pass so that you can check sub trim level in the AVR followed by the complete 8 pass calibration. So this can become time intensive because you also might have to adjust the gains on the subs volume knob when you combine the output from the DD system.

Once you have determined what sounds the best in your room you can then plan out how to hardwire the second one and remove the wireless sender.

I really do not anticipate you needing to mess with the phase switch on the ULS-15. Leave both at 0. Then what you would do is play with the distance setting for the subs in your AVR. If Audyssey sets the distance at say 10 feet, adjust the lenght so it reads farther away, say 12 feet, play an 80 hz test tone (if that is the crossover frequency you have chosen in the AVR) from your BD player using the supplied CD from HSU. What you are listening for is a greater output from the subs at the LP. You can even use your SPL meter for this process. Play the 80 hz note at the distance that Audyssey automatically had setup then lengthen the distance and replay the 80 hz note.

Am I making any sense to you about the phase? What we are trying to achieve is the subs cone movement is playing in sync with your main L/R speakers.

And as you know you can always call me for further help. Of course you really should pay the first invoice I sent you.

Got the 2nd ULS-15!!

Holy cow the room sounds like IMAX now. Exactly what I was shooting for.

Once i recieved the 2nd ULS-15, I gain-leveled the room (was using level-gain) and removed the IL120. Sounds amazing... right where I wanted it to be.

Thanks for the help HTG.

Pics have been updated!

I've only been able to listen to 'Clash of the Titans' and WOTW earthquake scene (5?) but the the WOTW scene just blows up the room. I can't imagine what quaddrive would sound like (never will... i'm satisfied) but with the two subs firing in seperately but equidistant to the primary listening position, it's impossible to localize the bass, even with the crossover in the AVR set to 100hz.

I'm hoping to get through more material, but the rooms officially too loud for my 8-month-old daughter to be in most of the house while the home theater is running hard. Looks like Terminator Salvation will be this weekend!
