Throwing a question like that out, you will get 20 different, all great, responses from 20 different people. There are also many variables to consider too that you don't mention....room size, room quality, average volume you listen at, type of music, price range, etc...

I have heard Emotiva with CM10s and 802 Diamonds and was not impressed at all. My friend who had the Emotiva stuff sent it back within the 30 day trial period and replaced it with Rotel and was much happier. I have no experience with Outlaw.

My vote would be the McIntosh MC452 stereo amp pumping out a rated 450 wpc of kick ass power.

I heard it with the 803s and 802s, using the 4 ohm binding posts with both, and it was outstanding.

Throw this guy out an offer of $4,800 or so and see what he says...

I also know a McIntosh dealer that has a demo model MC452 with very low hours on it, I can message you his contact info if you are interested.

If that is out of your price range, Rotel is excellent quality at a lower price point than McIntosh. They just came out with a new stereo amp, RB-1590 at 350 wpc, MSRP is very reasonable $3,000. You can probably find a dealer offering 10% off list and get it for around $2,700. It would be an excellent choice for the 803 or 802, and a hell of a bang for the buck.

At the end of the day, take what we say with a grain of salt and get out there and audition for yourself....or better yet...get dealers to loan you stuff to try in your environment.

I have a friend driving his 803D's with XPA-1 monoblocks and he's happy with them. He was using an XPA-2, and that was fine as well, but decided to upgrade when the XPA-1's went on sale shortly after he purchased the XPA-2. There are lots of good amplifiers around...

I have my 803's paired with a XPA-2 and it sounds great to my ears! Sure Mcintosh, Classe, or Rotel would probably sound better but for my budget Emotiva was a great option. I definitely don't feel like I am missing anything with the XPA-2.

Amplifiers referred to as "digital", such as the K3, are Class D amplifiers.

Here is a pretty detailed explanation....

This is a question for owners of the cm8, 9, and 10. I'm looking at upgrading from my 683 s2 to the cm10 s2. The question I have is, is the paper/Kevlar woofers fragile? It seems the phase plug or cap that on them would be so easy to dent in. Why would the 600 series use aluminum and the cm use paper/Kevlar? Is it better at producing lower frequencies?

I owned 600 series speakers, CM9s and CM10s and never found the bass or mid-range drivers to be "fragile".

The very first pair of B&W's (and the last as I've never had the $ or space to do larger than bookshelves justice) were (are) some DM600s3's.

Going on their 12th year with me I've never really had a problem listening without the ASW600. Would I like a larger bass presence? Definitely! These things are only 5½ inch woofers.

But the bass they give, they give in spades.

Came home one night to my Cambridge 640V2 amp cranked 11-an un listenable volume for me. But turning down there treble control on the Cambridge got rid of the piercing highs (but still too loud for me) revealed tight (plugs always inserted) and accurate bass, the woofers weren't even breaking a sweat.

Cranking the bass knob started to introduce some nasty at around 75%, but this was the amp I'm sure. While rated at 75 watts, and said to give the performance of higher power amps, when artificially raising the base it started to lose control.

This was all at max volume mind you. I can take a video tomorrow of me poking the cone's if you wish.

Regards, (for the vast majority of people :-p)

Whatever sounds best to you!

You'll want to check the manual as well. I think the lower bass port is ~30hz with the plug.

I'd probably go small with any HT type use, and large with music. But this really depends on your sub, your musical taste, your room, etc, etc.

With a 10 minute AVR calibration for both (if your AVR can use different profiles in a non rocket science manner), I'd just trust my ears.

Are you removing the built-in crossover? If not, adding another set of electronic filters is thorny.

Thought about this more. Are you talking about the phase plug itself, or the actual cone?

"When a dust cover isn't just a dust cover....." mushroom shaped plug does look to be a bit more fragile than any bullet shape, but you shouldn't be poking it with your finger. :d

As far as the paper/kevlar vs aluminum cone I'd say the kevlar is durable. It also has features like no surround, different voice coil/plug, etc, that the aluminum driver doesn't have.

Basically it isn't just material. The current kevlar drivers have newer/better technology than the aluminum drivers, which are basically conventional loudspeaker tech.

Dust covers are usually attached to the voice coil and inner diameter of the cone and, therefore, are part of the moving mass. The central plug, regardless of the shape, is usually mounted to the pole-piece of the magnet and is fixed in position. Its shape can play some role.

They are solid brass on mine (800D2, 804D) but I suggest you test it carefully by yourself to confirm yours are similar. BTW, the better protection is to keep the grilles on.

The bullet phase plug is plastic on the N800 and 800D series as the grill attaches to the center of it. To listen with the grill removed the N800 and 800D series came equipped with aluminum replacements for esthetic reasons (no hole in the center). This changed with the 800D2 (Diamond) series as the grill attaches magnetically to the surround negating the need for plastic phase plugs with mounting holes.

Learn new stuff everyday. Engineer looking at marketing material instead of actual assembly diagrams = wrong conclusions and bad advice.

And you guys are out of my realm!! Took a look at my cheapy 600s3 which revealed the aluminum plug look, bury the bullets are attached to the cones.
