Using Professional Amps On Home Theater Speakers

.
Ckoffend, I used Carver Silver 9t monoblocs (900 wpc @ 4 ohms) to power them. One pair of monoblocs did a good job, but with two pair of monoblocs in a biamp config, the speakers take a quantum leap and becomes a totally different speaker in a whole 'nother league. I had five pairs of those monoblocs and sold all of them, they were 20 years old. I suspected things may start to go wrong with them in the near future, so I sold them before they started to fail. The fees Carver charges to fix them was more trouble than it was worth. I also used the Sunfire Signature (1200 wpc @ 4 ohms) stereo amp to power them. I also needed two of those also to get the most out of the speakers...the Carver monoblocs were better than the Sunfire amps. I don't know what they were designed for, but one pair of bi-amped Kappa 9 can fill this room with ear-splitting sound without breaking a sweat with no distortion.

I had considered getting rid of the speakers too because they are so hard to drive.

I'd hate to see your power bill.

I don't dispute the quality of the performance of these speakers, as you seem to be quite enthralled by them.

Perhaps you could consider using these for your fronts and finding alternative speakers for your sides and rears. These alternate speakers are really more support based anyway and perhaps the Kappa's are being "wasted" on the intended purpose and location in some regards?

I got into HT for a while, ended up with 5 Wilson W/P 5.1s, but in the end, I didn't think the rear ones were really being put to good use - especially more so since I am not a movie guy.

Just a thought and it sounds like it may address some of you issues between amplification, speakers, and room fill. Part of me thinks that you are being forced into sub quality amps in keeping your speakers and based on the budget, and if this is the case, I suspect you will be disappointed after spending the money and not getting what you want.

Again, I would start by going to Guitar Center and renting the amps for a weekend, tell them how much power you need - if its 2000+ watts per channel, they'll have it. It will end up being the cheapest way for you to determine if you can go "pro level" amps.

I totally forgot about Carver. 7 old Carver cubes will blow your roof off-sound like crap but wow will it be loud!

I have an original QSC PLX 2402 that's used to power a Bag End 2-10" and an ELF 18". I did use it my two channel system for a few weeks. The PLX series has a switching power supply (not to be confused with class D) that is mechanically noisy for home use. QSC offers a wide range of amplifiers with different power supplies some of which are used in theater applications.

They are physically bullet proof. In the two channel system it lacked a very slight last little bit of finesse with a slightly closed in sound stage. On the other hand the bass weight would compare to the very best in the audiophile world.

Their low cost and customer service is outstanding. Used often in Bass amplification their representative is a fixture on the BassTalk forum.
