Was waiting to see how long until someone mentioned that.

What happened is the wire going to that one enclosure was so short and tight that I had to rotate the enclosure around for it to reach the terminal. They were all offset diagonally on the back.

Love the work in progress. Though my back is in fear of that couch... always room for improvement I guess.
I need to read up on how your sub riser performs...

Scott, it was great talking with you at Brandon's GTG a couple of weeks ago. A few projects down my endless list is re-making my 4 Pi speakers into a three-way system with the midhorn (and possibly a second JBL 2226H driver just for fun). When I get to this project, will be hitting you up for advice.

Have you listened to Roger Waters new Wall blu ray? It would be epic on your system. May induce flashbacks so be careful.

Hey, you too! Hope we can catch each other again at the next big GTG. Yup. Hit me up. Sounds interesting. Will have to be a active/passive hybrid system it sounds like. Guaranteed to be killer though.

Nope. Don't have it. Probably won't get it unless I hear it somewhere and it impresses me.

Scott,

Out of curiosity, do you currently have your eye on anything new for the theater? Also, great job with the setup....looks intimidating, and crazy fun, at the same time.

Hey, Kevin! Where the hell do you keep going off to?

Yes and no. I've finally reached a point in a long, long time where my room feels "complete" with no nagging urge for the next item to upgrade or replace. Sure, given the money I'd like to get all sorts of thing changed but in it's current state it is very adequate. But .... I do have plans. That's half the fun of this hobby is the next change or upgrade.

I think the next thing I'll tackle is the side surrounds. As seen in the pictures, they are quite intrusive. I'm thinking about removing the acoustic treatment behind them and somehow mounting them in that area. Will push them closer to the side walls by half a foot which doesn't sound like much but will make a huge improvement in several ways. Haven't figured out how I want to do it yet so for now they stay. Another thing is I might go about "blacking out" the rest of the room. Will probably just get some material each month and work my way front to back. Actually do not need to do this much so I'm in no hurry. I'd love to upgrade all my surrounds and heights but if I do them all at once I'm looking at two grand or so in new speakers. Ugh. Rather not.

Realistically, I probably won't get much new hardware for some time. I see my next thing being a UHD Blu-ray player when they come out. Or not. First generation players always suck ass. Maybe I'll just wait for OPPO's first player. They said they won't have one the first year of the new format so it'll be a while which is fine with me.

So no... not much, Kev. I'm up to my eyeballs in bass and awesome dynamic sound. New projector is excellent and I'll have to quadruple the price I paid for it to get a worthy upgrade in PQ. No complaints about the OPPO 103d player. Atmos sound from my new Yamaha is also excellent. Any improvements in sound will come from different surrounds or better placement of which I have little room for change there.

Come on up sometime and check it out, Kevin.

Sweet manchego! That's quite a setup, well done. Just one question...when you add your front wides, will your right one be in front of or behind your grandma's shower curtain? If positioned behind, is it acoustically transparent?

Yes, yes, very well.... very well.

Notice I covered my granny curtains.

Probably will not do wides in this room. Don't need them.

Didn't post that.

It's roughly 18ft long x 10.5ft wide x 9.75ft tall.

How did you integrate the six Atmos speakers? I understand you have four channels matrixed into six using some version of Dolby Pro Logic II. Did you set the speaker distances on the Yamaha or on the Harman Kardons? Also at which stage in the setup process did you run the room corrction on the Yamaha, before or after enabling PLII?

I will most likely do the same approach for a 7.1.6 setup in my 12'x12' room once NAD get their act together and release Atmos MDCs for their AVRs.

I like this build, it is insane.

Hello, Mashie.

Yes, I extract a common center image from the two sets of overheads. Dolby Prologic 2 is the post decoder that extracts my two middle overhead speakers. Movie mode in particular but 'Music' mode is good for "center fill" of the overhead sound and then I can also use Stereo/Direct for a bypass of the whole thing if I want. The main receiver feeds the two auxiliary receivers by RCA cables. Front left and rear left to one and front right and rear right to the other. Here is a block diagram of the hookup:
Spoiler!


I run all my main calibrations first on the Yamaha with decoding bypassed on the two extra receivers. Assuming all as if 7.1.4 layout. After main calibration do I activate PL2 decoding and then tweak here and there til just right.

Thanks and good luck!

Hi Scott,

Thank you for the information, can't wait to implement it myself.

That room is sick!!

It's been 25 years since I was in car SPL competitions in my '88 Civic hatchback, so I sure wish current wife loved bass

Good thing she is a great cook

Congrats and enjoy

Scott, have you thought of using the miniDSP program for extracting center from stereo signal? May be a little more rack friendly than two extra receivers.

Or do it the old-fashioned way: run the positive lead from the left and right channels to the center. The disadvantage is that you have no separate control over the volume (unless, of course, you wire in a potentiometer).

Yes I have, actually. It sounds like a decent approach on paper but looking at the diagrams available it isn't clear if the MDSP solution not only "makes" a center output but also cancels that same information from the L&R as PL2 would. Would only be useful as a "center fill" if that information is left in those channels. Not the worst thing ever but it's an investment that will not net any additional versatility or performance over what I have now.

If I knew for sure then I would definitely do this. Or if I get bored sometime I'll try one. Idk.

I love the insanity of this. It's just pure overkill.

How far do you sit from the screen, and how do you like the Center Stage UF material? I'm thinking about going AT in my next setup...

Hey, thanks!

I sit roughly 10 feet away and the screen is 110" wide (126" diag). I really like the UF material. It's just as good quality as their regular XD material (I had that before the UF) just that the weave pattern is MUCH smaller. You really do have to put your face against the material to see the gaps. You can barely see the pattern at all even about a foot away. At the seat, I don't see the weave pattern at all which is what I was going for. The old XD material I could just make out in full, bright white backgrounds at the same distance.

I would highly recommend the UF material. Just note that it is lower gain than the standard XD material.

Above awesome! We have the same taste in crazy dynamics it seems. I bet it sounds awesome in such a well treated room. I'm working on adding more acoustic remedies to my own room. On the wall behind me I have 2 feet deep stack of insulation from floor to ceiling and it really helped clean up that waterfall and improve the reverb of the room.

What exactly are you using for the 10" horn loaded midrange and what is the passband for that driver, please?

Thanks! Haha, yes we do! You can tell when someone is serious about dynamics and uncompressed output because their system will look like yours or mine.


The hornloaded midrange is a kit from Wayne Parham of Pi Speakers. Here's a link: http://audioroundtable.com/forum/ind...t=msg&th=16581

The driver is an Eminence Delta10.

I use it between the JBL's and high frequency horn. The bandwidth is roughly 300hz to 1.2khz of which I can change as I'm fully active. I got the best response (at the time of installation) with these frequency bookends and stuck with it. I could very well run the HF lower and/or the JBL's higher... or whatever. Because it's a sealed rear chamber, I could run the midhorn full range but it will run out of throw below 100hz at high levels. In fact, once I messed up some settings and watched quite a few movies near reference with the JBL's effectively off and the midhorn doing all the work. I thought things sounded quite off til I found the problem and fixed it. But it held up!

Haha, yes! The danger of a system like this is it will sound good all the way to total deafness.

Thanks for sharing the details. That's a very interesting horn, and I think I understand why you are using it drawing from my own experience with 2226 crossed too high. We have the same pass band for the mid too. I found that the addition of a dedicated midrange driver elevated the perceived tightness and clarity vastly. Speaking to the choir here, but one part of the tactile feel is the actual punch, another thing is the sound of the punch. 2226 is a beast driver at producing the tactile punch, but the 10" driver makes sure that the punch sounds as tight as it's felt. It's not just in terms of punch though, voices etc are reproduced better. Less muffled sort of.

Haha, good thing it didn't break. I've had my fair share of mistakes too, sometimes even without noticing. Like forgetting to turn on the subs and thinking the bass is as awesome as ever

For music listening I bet that all of your sealed 2226's can do a very nice job even without subs. I high pass them whenever things are going to be pushed. Getting more drivers added has the benefit of avoiding that high pass. I recall seeing that was one of the design goals you had with all the drivers too, no?
