In all the A9 reviews, it says these open up beautifully if adequately powered. What is min recommended power to maximize the listening experience?

50 - 500 watts is the range provided by the manual. 50 watts per channel is what you need for a minimum. I have an Onkyo TX-NR818 with 135 watts per channel powering the units along with 7 other speakers for a 9:2 surround system.

I would say about 150 Watts RMS. You really need some nice clean power to drive these speakers. I would highly advise to Bi-amp your speakers: meaning get an external amp in addition to your Receiver's amp.

I would recommend at least 250 to 300 watts. Get a crown xls 1500, amazing amp and plenty of juice.

Most people say around 300 watts each, I went with 600 watts each and positively love them. The wattage is needed to get the mids and woofers to work properly. If you power them right and run them full range a sub is really not needed. Remember most recievers are rated two channels driven, so an external amp is a must. These speakers sound good with 90 watts, they sound like a completely different speaker with 300 watts, they go from good to great.

The truth is that at least I could not say ... I use it with "Emotiva" amplifier, and the truth, sound speakers, making experience the experience of being "there" the artist.

That will do fine, particularly if you bi-wire. However, you wont be able to drive the speakers up to (or near) full volume. I initially had a 100WPC amp driving mine, and the speaker would clip at high volumes. Only when I upped my power source could I open them up without blowing a fuse.But if you plan on moderate listening you will be fine. Any more and you might find the cops at your door anyways.

Blow them out of the water in every regard IMO, less bass in these though (not an issue for me as I would rather controlled bass than more bass) also depending on what you are used to they are relatively bright as far as lower mid range headphones go. They are unweildy to take out in public if you aren't using them at home though (the M50's do a good job outside) I would recommend going for the A900X's over the A700X's if you can afford the difference though, the Aluminum housing makes a rather large difference imo.

They are very efficient speakers and thus do not require a lot of power to drive them. However, they can handle higher power and perform excellent when you feed them 100 plus watts per channel. I have a denon 3313 which is rated as 125/ch.

Anything that can deliver at least half of the recommended power which is 110 watts rms per speaker. I currently give them 50 watts rms and they sound great and are loud enough for me. Make sure the amplifier is CEA 2006 compliant. All of the information can be found on Crutchfield or sonic electronix. I recommend Alpine Mrv-F300 or something similar as it will be slightly cheaper than the PDX-V9 if your on a budget. If you can splurge a little more go for it and get a PDX-V9. Both amplifiers are a great buy in my opinion

the problem with these are they need at least 300 to 500 watts. other wise there going to distort and blow tweeters and mid like crazy. if you got the power you can break them easy. hope this has helped you.

I'm running 6 speakers and 1 10 sub. I have plenty of power to go further. My 10 sounds amazing. I'd go to a 12 if you listen to hip hop. If not a 10 is fine.

I am running these off a good after market deck with no amp. all I can comment on is sound quality is pristine. I'm sure if you push enough power on any 6 by 9 it'll blow..

My advice would be not to drive these speakers to maximum wattage. However, these remarkable bookshelf speakers are the best I've heardover 40 yrs of trying to find a certain quality and would think that they would be very adequate in a multi-speaker array, ie 7.1.

At this point I have used them only for listening through my CPU and volume has not been an issue. Reasonably comfortable for long periods. I hope to get to the big stereo soon, but have to rearrange the furniture first:)

Depends on how efficient the speakers are. 50 watts per channel should be plenty for most home listening. It works for me just fine.

will power to max capacity of speakers. 15 watts clean with bigger power-supply. Not going to Rock a night club but more then enough for casual listening.

I have not a clue, any respectable amplifier with 20 watts RMS from 20-20KHz should do it. I use an Yamaha RX-V573, 70 watts @ 20-20K, 110 @ 1Khz (big whoop). The point is I never need a whole lot of power, read the specs, 96 db 1 Watt/1 meter, pretty efficient, up there in Klipsch RF territory and they sound better than Klipsch RF-62's. If you have a clean old two channel receiver with 50 watts x2 channels, it should be plenty for a good sized room. My listening room is 20' x 11' and along with the F12 these guys always sound great.

Depends on how much power you are putting into the system. I have two of these on an AQ1200. But they could take more. If you want more volume at lower rms, use two subs. Double cone volume-> 3db, double rms-> 3db. 6db I'd twice as loud to the human ear. As far as sound quality I think these aren't the most accurate subs but they definitely could be a lot worse. If you listen to lots of rap and boomy sounding bass, go with this sub, ported at 35hz in 1.5 to 2 cubic ft of box

Don't listen to these overrated "you need at least 100W". These are very efficient speakers at 93db/W, and they don't need that much power (which is the point of efficient speakers) - at 22W @ 93db efficicency produces about same amount of sound as 60W at 88db efficiency (most people don't even look at efficiency values). They were plenty loud in my miata with a 22WRMS/ch head unit. I've also had kappas in a different vehicle with 50Wrmsx4 amp. They'll benefit from more power (not so much volume, but clearness when cranked), but not as much as other's are trying to make you believe. Don't listen to these overrated "you need at least 100W".

I used them with this tube amp (http://www.amazon.com/GemTune-Class--Tube-Amplifier-EL34-B/dp/B00DRUY6EG/ref=sr_1_2?s=electronics&ie;=UTF8&qid;=1449284595&s;r=1-2-spons&keywords;=tube+amplifier&psc;=1) that only has 10 watts per channel, granted, a bit more power than you are asking about. It filled a medium sized room well. Say 15x20 feet. But as others said, it won't rattle he windows. You could also give this inexpensive amp a try (http://www.amazon.com/dp/B00F0H8TOC?psc=1), the sound is surprisingly good.

I have a pioneer vsx-1121K and have the A9's Bi-Amped, hitting these with 220W per channel. Even hitting these speakers with this amount of power they still aren't working hard. I'm looking into getting either a different receiver or a seperate amp to make these guys really shine...
