I have been looking at all the posts and threads for a while now and just decided to sign up and get serious about my research and hobby. I just bought my first house and may finally be able to realize my dream of having a cinema/gaming room. I wanted to know if it were possible to build a system for a room that is 20'x20' with a 20' Vaulted ceiling for under $1500. I have looked at the Mirage Nanostats and Definitive Procinema 600 and then add the appropriate surrounds for 7.1. Are these powerful enough to fill a room that large? Any help would be greatly appreciated!!

Good question to ask. The speakers with small drivers like that would not be a good choice for your size room, and the subs with those packages would be virtually useless unless you sit on top of it (sub performance is related to room volume).

You might want to research and ask questions in the AVS speaker forum, where suggestions for speakers for this kind of budget get answered all the time. For a sub for that size space, look at the Premier Acoustics PA-150 (which can generally be had from Acoustic Sound Design for between $300-350 if you make them a bid). Also, don't put tons of money into a receiver. Better to buy and entry level receiver like the Denon 1612 and put the rest into speakers and sub.

First of all what all are you expecting/wanting to get for $1,500??? Is that just for 7 speakers? OR Sub included? OR Reveiver included?

You will probably have huge issues with room modes and nulls with standing waves making certain freqs very exaggerated and others canceling each other out, because your room is square.

!) Settle for 5.1 (or 5.2 maybe, with that room).

2) Watch out for specials on discontinued AVRs.

3) One idea for speakers:
Fronts: Infinity Primus P253
Center: Infinity Primus PC251
Rears: Infinity Primus P153
Sub: Infinity PS410

That will shoot about $1300 of your budget, so you'll have to find a real deal on the AVR.

The Infinity Primus speakers are a nice choice.

However, any 10" sub like the Infinity PS410 is completely inadequate for your room size. Plus, Infinity subs are known to be plagued by amplifier problems.

im thinking that with the budget a better quality 5.1 would make more sense after all the recommendations. i have pieced this system together and think it may do the trick

Fronts: KEF C5 floorstanding
Center: KEF C6c
Rear: KEF C3
AVR: Denon AVR-791
Sub: PA-150 from above recommendation

i can always add surrounds later to complete the 7.1 if that is a better route to go.

What problems? (I'm not challenging you, just seeking clarification.)

Just remember that in 5.1 rear surrounds DO NOT exist (side) surrounds do. So you add rears if you want 7.1.

Quite a few people on AVS have reported long term reliability issues with the amps on Infinity subs.

If you look at the model Infinity speakers involved, they are mostly legacy designs dating back to when Arnie Nudell was running the place. Some of them used the Watkins woofer design that had a very atypical impedance curve.

Get real. With your budget you can only cover 10x10 area in your room, and do not expect any real bass too. If 10x10 listening zone is Ok for you, then follow recommendations above. But bass will always be a problem - do not expect any decent "explosion" sound unless all your current budget goes into subwoofers only. You can't overcome law of physics regardless of what you was told by sales guys.

+1 to the infinity Primus setup.

Also reccomend an Accoustech sub as an affordable option.

I did the following about 6 months ago:

1 Denon 2112
2 x Infinity Primus P 363 (fronts)
2 x Infinity Primus P 163 (surrounds)
1x Infinity P351 (center)

1 x Acoustech PL-200 sub.

If I remember right, I did all of this for less than $1500, which is close to your budget.

DEFINATELY skip 7.1 for now on that budget. Buy a 7.1 capable receiver, and add the other two channels later. Most source material is native 5.1 anyways IMO.

Beauty is in the eye of the beholder, but a decent sub can be had within this budget. Like the Acoustech PL-200.
