I went with the Erskine select plan based on advice on this forum. My room will only be 17.5' long by 13.25' wide before screen wall so I had to make some sacrifices. I had wanted 2 rows of seating but settled for one. Also I had wanted a bigger screen but was advised there wasn't a projector that would work with my short throw distance for my budget, still not 100% convinced on this one and would really like the screen bigger though.

Recommended Equipment List:
-Stewart StudioTek 130 Micorperf Screen
-Runco LS-5 projector
-Audyssey Capable Receiver/Preamp (Picked up a Denon 4520CI on Black Friday sale)
-7 channel amp
-Procella P6 for C and P6V for LR
-Triad inwall 6 subwoofer
-Triad Inwall Bronze surrounds (x4)
-QSC DSP 322ua
-I currently have a Rythmik FV15HP sub they incorporated into the design

I have been looking at the Noesis 212HT-LP for LCR but not sure if I have enough room or how it would affect the design??

Interesting. Exact same size as our room but I have asked Dennis/Shawn for 2 rows.....going to be interesting to see what they come back with.

Screen size looks about the same as what I came up with myself (width at any rate - I want a 16:9)

Coffered ceiling?

Not yet going to look at other options besides their recommendation as well. Haven't started developing the basement yet so I still have a while to figure that out.

Expect the Stewart 130 mp to be 60-70% more that same size Seymour-SE 4k screen. At 12 ft I could see perfs on the 130...........be very careful and check screen material yourself before purchasing.

I made many changes to my EG design and am glad I did.

Just a rough estimate of 3-4K.

Then use the same number.....ie. 60-70% more than 12ft Seymour-SE 4k screen.......about the same price, biggrin.gif



My room is is 25+ X 17 X 10 ft

Picked up some equipment and ordered some JTR 212HT-LP speakers for LCR.

Curious...What's the purpose of the QSC DSP 322ua?

Seems this is a minimum requirement for any DE design, but having only 2 side surrounds (per drawing above) and Audyssey Dynamic EQ + Audyssey Sub EQ HT built in to the 4520, I don't see the point in the added expense.

See the Supercharged 10second II here :

See the ConcreteBunker Build w/8x18" IB subs here:

I don't really need it but got a good deal on it used and I do plan on adding a 3rd sub at some time. According to Shawn it's still a more capable device than using Audyssey alone. I'm going to be getting a 3ch amp for the LCR and running those plus the subs through the QSC and the surrounds and rears off the 4520.

I understand it does a "better" job than what Audyssey alone, but factor in the cost of the unit and you have gone well beyond the point of diminished returns. I would say it is even beyond needing a 322ua for a 3rd sub. There are many devices out there which would allow you to incorporate a 3rd sub for thousands less than the DE recommended 322ua. I know it's plenty late to suggest this now since you already own the 322ua, but DE seems bent on not deviating from certain components regardless. Have you looked at the MiniDSP at all? It will do everything you need for many THOUSANDS less than the 322ua. I'm sure those thousands could be better used on something else which you would see/feel/hear a MUCH bigger difference from.

Is it too late to post that 322ua up on Craig's List or eBay ?

Also you would always need to pay a experienced calibrator to calibrate the 322 initially and subsequently to calibrate it if it ever malfunctions. I read somewhere qsc is going to discontinue the 322 for a newer product and so getting rid of the inventory.

I did look at the MiniDSP but I didn't pay anywhere near retail for the 322ua I figure I'd try it and if it doesn't workout sell it later.

Since you'll have amp channels left over in the 4520, I would add a pair of wide speakers in the front columns to bridge the gap between your front and side speakers.

I got a 3 channel amp because I went 11.x, and my 4520 (same as your's) only can handle 9 channels.
Curious: why spend coin on a 3 channel amp when your 4520 should be able to handle the LCR?

Also, have you considered going the Audyssey Pro route rather than the QSC DSP?

Only real reason is to have more power in reserve. I was thinking about getting 3 Crown XLS1500 amps each bridged for the LCR. I'll probably try it first without though. I thought with Audyssey Pro it treats two subs as one?

"No. XT32 pings each sub individually and then sets the level and distance independently for each sub. It then EQs both subs together, taking account of their interaction with the room and with each other. Because the Pro Kit uses the 'base' version of MultEQ in the AVR or AVP, using Pro will not give you the same result as an XT32-equipped unit. In other words, your dual subs will still be treated as one sub, with distances and levels NOT set independently; however, the subs will still be EQd together."

Looks like a reasonable plan overall for a size-constrained room. Being partial to 11.2 channel matrixes setup, that's what I would suggest from the outset. To get a great bass response curve, I prefer as many subwoofers as possible also but of course your room may not easily accommodate.
