Compression drivers have the hardest response to work with and can cause offensive sounds if they don't get filtered properly. But their huge efficiency provides insane dynamics. The dispersion is related to the chosen horn, but it's always much narrower than a dome (usually that's a good thing). They usually have bad response above 10khz.

Ribbons have high distortion at lower frequencies (below 3khz about). But have good sensitivity. Above the area of bad distortion they have very low distortion and extend well beyond 20khz. Their sensitive isn't like a CD but is still quite high and has good dynamics for the most part. The dispersion is wide like a dome horizontally but narrow vertically depending on the ribbon height mostly. Their dispersion and low end capability makes them a hard choice but if used properly are thought to have the highest reward.

I have reviews of 3 ribbons on my youtube channel if you want to see more about them. I plan on using a ribbon in a 3 way tower so I've been testing them a lot.
There are also the AMT air motion transformer diaphragm tweeters that are similar to ribbon designs. They can be crossed lower.

So I am currently looking for a center channel to go with my B&W 685 S2. I have a 6.5inch tall by 16.5inch wide by 19inch deep space that I would like to fit it in. I also have a ton of 3/4in MDF laying around that I would like to use for the build. I am wondering if any of these new kits might fit the bill? From what I have looked at the S2000 is the only one that would fit. I know dimensions are critical but could some modifications be made to fit my space and not negativly affect some of the other kits. Thanks in advance

It makes some sense if you have one of the more elaborate home theaters (group seating) where wide dispersion could be useful, or are attending a GTG.

For music listening, which is usually more intimate and has a midplane "sweet spot," it doesn't.

The waveguide/horn focuses the sound towards the listener and away from the reflection surfaces.
As do "oversized" mid-woofers putatively crossed too high.

I'm having problems connecting to the DIY Sound Group page. I haven't been on there in awhile, but now when I go to their page, it asks for a username and a password, but I can't access the page, and I can't find anywhere to create an account. Anyone out there have any info/ help?

Message was up past couple days that Erich will be switching over to new website design this weekend. I think this gap in availability is part of the switch.

I agree a "new website coming" note has been up for that long. I only recall the "it's happening this weekend" up for a couple of days.

I have an Yamaha RX-V781 AVR.
I would agree if we were talking about speakers a grand or more. But we are not talking exclusively about $1000 speakers.
I am interested in the S2000 MTMs which are $250 a pair and fall into the same budget conscious category as my mid range AVR. I'm sure there are lots of do-it-yourselfers in the same boat.
That being said, I think should be ok with the S2000s according to the Yamaha owners manual.
"When connecting 6-Ohm speakers, set the unit's speaker impedance to "6-Ohm min." In this case you can also use 4-Ohm speakers as the front speakers."
YMMV

For yamahas you shouldn't actually set the switch to low impedance. You end up with less power. It's there so Yamaha could meet an energy certification.

I do realize that but thank you for the advice. That is worth pointing out because if is an often misunderstood setting on Yamaha receivers.
My point was to show the 4 ohm reference but I left the full quote for context.
I guess I will take them at their word and try some 4 ohm
