AV Receiver Output 150W per Channel

[SAPSEC]

Hi folks,

I look for an AV receiver which could output 150 watts (for 8 ohm speakers) EACH channel in 5.1 set up. Does it exist ? If not must I consider using external 5.1 power amp ? Want to set up 2 front requiring 150W RMS, center requiring 120W RMS, and 2 rear requiring 100W RMS.

Thank you for your advice

My advice for that kinda power would be to go separates. An external amp and processor or receiver with pre outs for all channels. Some lower models just do 2 channel pre outs. Make sure it has pre outs for all channels. Just my opinion though.

I think Yahama RX-A1060 has all pre-outs for 2 fronts, 1 center, and 2 rear surround. I see in the back - but not sure .. do you know ? Thanks

Yup it's gotta them. Good choice too. Look at Denon though too if your gonna use it as the processor. From what I've read Denon receivers are very good as processors.

Do your speakers actually require that amount of power? Or are they just rated to it? Depending on their sensitivity and your listening habits, you do not need to send the max power they are rated for in order for them to sound good or get loud.

There are some higher end receivers that offer that kind of power. Yamaha - RX-A3060, Anthem MRX720, Denon AVR X6300 to name a few. But keep in mind 140 or 150 watts per channel is based on specs with 2 channels driven. You most likely won't need that type of power for surround speakers. For any of those amps you should be prepared to shell out around 2k though..

Yep. Midrange AVR with an external amp to get that kind of power IMO. AVRs are more likely to be surpassed feature wise so going with a flagship is not the best plan unless you must have specific features or you don't care about features at all and will keep it for 10+ years.

Along the same lines, how did you arrive at the 150W figure? what speakers are we talking about? A speaker wattage rating is a MAX rating before something fails, not how much is required to operate them.

The Denon 7200 can output 138W into 8 ohms @ 1% THD x 5Ch simultaneously.

My Denon 5308 can output 185W into 8 ohms @ 1% THD x 5Ch simultaneously.

The RX-A2060 can probably do the job for you without an external amp, and if you do need one then you can get one. For Yamaha, if you want to be sure you have high enough pre out voltage to drive most power amps, don't go for anything lower than the RX-A1060.

These speakers are all fairly efficient with a sensitivity of 90db. It will not take a lot of power to make them sing. In fact, the spec sheet (http://ca2.monitoraudiocdn.com/downloads/brochure/Bronze-Brochure-2015-LR.pdf?mtime=20150518164428) for the Bronze 6 (the largest speaker which needs the most power) recommends an amplifier of 40-150 watts. You do not need an AVR that outputs 150 watts per channel. Any manufacturer's AVR that outputs 100 watts should be more than ample to drive these to "loud" listening levels without clipping.

Those are peak numbers. Thats usually the point of meltdown. During normal playback only a few watts are used. Big peak numbers can be seen during large transients but don't be fixated on matching peak numbers with an amp. Fwiw, the older denon 4520 is rated at 150 and is a beast. Lovinthehd has one. He can probably shed some light on that.

Those numbers are more or less a melting point for the crossovers. I doubt your speakers would handle that that much power continuously for long. 120-130 watts should be plenty. What's the sensitivity of your speakers?

90 db.

90 db.

Assuming they're actually 90db, that's pretty easy to drive. They won't require as much power to reach higher spl's. Try playing with this spl calculator. Enter your speaker sensitivity, distance from them, etc, and you'll get an idea of how much power you might need.
