Home Theater Power Amplifier Help


Audiogon Community;

I am leaning toward separates in my HT setup, and B&W in-walls.

Right now, I am researching the amplifier power requirements for the system. The room dimensions are 17' x 17' x 7'6". The room volume is ~2,200 cubic feet.

Based on the speaker sensitivity, room size and accoustics and power output relationship I come up with a power requirement of less than 60W per channel to drive the speakers.

Do you agree?

The two subwoofers will be driven off the controller.

Possible Power Amplifier choices include:

Rotel RMB-1066 60W x 6 into 8 Ohms!

Please comment!

Happy Holiday's,

Definitely agree with other responses. Get more power! I can only hope to discourage you from buying in-walls. Look at any reputable speaker company and you will never find a cabinet made of drywall and two by fours. You lose all flexabilty and possibility of accurate set-up and maximum sound focus. I encourage you to research ON-walls, example
Martin-Logan makes a scenario (I believe is the correct name) also Acoustic Research, Legacy, to name a few.
Good Luck

Thank you! Based on your comments, I am going back to the war department (my wife) to discuss this matter further! Sometimes it is not space, money or time that is the limiting factor!

Happy Holidays

Wheaton-IL, the above response are correct, but they are coming from a perfectionist orientation. Are you trying to put together a perfectionist system? If not, and I suspect you're not, your probably just want good quality performance at a fair price, then much of the above advice does not apply. For instance, you're looking at in-wall speakers. From a decor perspective they make perfect sense, they take up no space and the cables are hidden, but they don't sound as good as comparably priced freestanders. Only you and your family can judge if the trade off is worthwhile. You might want to consider Mirage's Omnisat speakers. $400/each including stands, plus they have a matching subwoofer. As far as power goes, remember that doubling the power output only results in a 3dB increase in headroom.

I assume you live in Wheaton. I hope you're taking advantage of the excellent music series offered each year at the College of Dupage. They have interesting artists and the hall offers very fine sonics. Best of luck!

Thank you Onhwy61 for your response!

COD is a first rate college, however, I have never taken advantage of their music productions. Based on your advice I subscribed to their mailing list this morning.

Thanks again.
