Bought these direct from Pinnacle, based in part on recommendations I read here.Good speakers overall, with astonishing bass for modestly priced bookshelf
speakers. They seem to be at their best with simpler musical textures in the
alto-to-baritone range, as well as anything with much percussion. I'm not
yet sure I like listening to sopranos or lush orchestral music on these; that
may change with break-in and better cabling. I'd give them a 4 for absolute
performance, and a 5 for performance-for-the-money. The bass and the low
price give them an edge over competitors such as the B&W 302, Tannoy M1, or
NHT SuperOne, at least to my ears.

Nice detail and imageing

I bought a set of definitive tech. speakers but couldnt bear to part with theese when I did. I use them in another room in a good old 2 channel set up an they sound very good.nothing else in their price range comes close.

Great range. Deep base, crisp highs.

Still thinking....

Great speakers. I went to every audio store within many miles of my house, listening to every bookshelf speaker i could with the same set of CD's. Pinnacle's performed the best in my book. I used them initially as stereo speakers. Now they serve as the fronts for my 5.1 system.

I have had a pair of AC650's for about a year now. I beleive I paid $215/pair via mailorder. Having listened to several other speakers in the $300-500 range, the AC650's were by far the best sounding. They excel in bass reproduction for a bookshelf model their size. The high freqeuncy spectrum is clear and smooth. They are an especially good choice for someone seeking a speaker that handles home theatre applications as well as a solid "audio only" application. They provide excellent imaging for audio, and a seamless soundstage in the HT appilcation. For those who are considering NHT SuperOnes,Titans or similar,listen to the AC650's....they perform better and arguably without a subwoofer
addition....not to mention about $100/pr less in price(ooops! I just mentioned it).A lot of $peaker for the $$'s

Big sound, low low price

I bought these speakers from onsale.com as CM-90. I email pinnacle presistantly asking what the deal was because I had never heard of them before. They finally informed me that they were indeed AC-650, and because of some deal with onsale they were called something else. I then went to box my speakers came in and tore off the white sticker on the side that said CM-90 and behold there it was AC-650. I was especially happy when I found the retail price of these speakers, becuase I only paid $99 for the pair. Due to the price and the outstanding quality I got from these unexpected wonders I must give the AC-650's the highest rating.

Great imaging, crisp highs, rich lows. Quality connectors and build

Rather plain looking

These are great speakers for the price. Bose can't even touch these speakers for sound quality and imaging. I compared these to a lot of higher priced speakers and would have to say that these are just as good if not better than most.

I bought these speakers about 2 years ago when I went to college. They replaced a pair of Mission's that were a hand me down from my father. I paid $260 for them. At 260 dollars these speakers have amazing sound. I have them hooked up to a yamaha rx-485 with a Marantz CD-48. The sound is wonderful. This ystem is not the type of system that will give the last word in detail, but it sure comes close. I have heard of people getting them for a little as 180 a pair being that they are discontinued. GIVE THEM A LISTEN. Pinnacle speakers, I think, are very underated. I never hear much about them. They are definately a well kept secret.

I had these for a year or so, they replaced an old pair of Polk 5jr monitors. I paid around $275 if I remember correctly - I think they list for $375. These were a definite improvement over the Polks, quite transparent, and surprisingly clean down to fairly low frequency. I ran them with a Onkyo 414 Pro. The finish and build is their weakest component, though even that is about what you'd expect from a $300-$400 speaker.

Bang for the buck, good support

I would have to be really picky to find something.

First the only bad thing to report: a bad 6.5 driver out of the box. I was shocked. Pinnacle's support was shocked. I assured them that I had swapped the drivers in the speakers and no matter what the driver failed to function properly. I received a replacement driver 2 days later, replaced the bad unit, put it in the PREPAID return box and shipped it from work. Time for replacement: 2 days Cost:$0

That's pretty good.

That aside these speakers have been outstanding. They play everything I have to listen to with at the very least acceptable sound quality. I picked them up almost a year ago for $199 (a pair) with the widescreen center for $179. I quite frankly love them. I am looking to get some of their Pinnacle Gold Rear channel speakers to finish out.

Other system components:
Harman Kardon AVR55
Infinity BU-8 Sub
Panasonic 110 DVD player (very unfairly maligned DVD player, 2 years with no problems and has never failed to play a disc)
JBL J520 bookshelf for rears

The panasonic is on deck to be replaced by a Toshiba SD1200 (for picture quality purposes), it was bad out of the box, apparently rare. I'm a magnet.

Beautiful sound,excellent price, quality construction

Can't think of any worth mentioning

I picked these speakers up for $175 open box, at Fry's Electronics.I have had these speakers for around 1 year now. Actually they have been lying around unused for almost 8 months. I had these speakers hooked up to my Sony shelf system. They sounded very flat so I never used them. I finally wised up and shelved the shelf system and purchased a Yamaha AX-592 integrated amp. What a difference! These speakers sound lovely when hooked up to my new amp. Jazz and vocal performances sound very natural and detailed. I wouldn't recommend them for rap, hip hop, or most modern pop music. These types of music seem to produce "wooly" sound. I think that these speakers shine when the music is not very complex. Put on some Sinatra, Sammy Davis Jr., etc. By the way, I have them standing on SoundDesign speaker stands. Definitely, get a decent pair of speaker stands, good speaker wire, a good amp, and you will get the maximum sound out of these speakers. The quality of construction is also very good. Just take a look at the binding posts and you'll understand what I mean. I have become a Pinnacle fan and hopefully within a few months I will be able to afford a pair of their Classic Gold Towers.
