Dayton PC105-4

What are the partners, tweeter and woofer?

On the PS95-8 is an anomaly from 1,5-2,5kHz with the resonance on 2k which is potentially difficult to handle. Both SB drivers got resonances at ~6k, which is pretty close to the target xo of 4k. The Dayton PC105-4 is the easiest to handle (if a poly membrane is okay for you).

The The 15MFC30 should probably play a bit lower than 4k.

I'd prefer the SB12MNRX25 or Dayton RS100P-8 which looks quite tame and easy to handle as well, I like the paper cones far more than the poly.
 
I've already got the PS95, WAW with a 5" Wavecor, xover still needs some tweaking. Agree about the looks. Think I'm looking for something a bit more efficient.

Parters are SEAS CA18RLY & 22TFF. This was in a 2.5 way I was very happy with until my last build based on a Beyma MC115 dome, which has me in raptures. Should have mentioned, I'm also considering the Dayton RS52 dome....

Agree about the efficiency. I was bi-amping with a MiniDSP so that really wasn't an issue. If you're looking at the RS52, check out the relatively new RS52FN. I like the top end response much better than the RS52AN. No nasty metal dome breakup.

Now, if you want to step outside the norm, here's what I settled on as a wide band driver for my O.B.'s: SB Acoustics SB20PFC30-4. It's unfortunately shaped but it sounds fantastic and the efficiency is there. Might be larger than you are looking for but you can literally run this without a filter on the top end. I am using these with a pair of Peerless SLS 12's and a Beston dipole magnetic planar per side. I've got a cap and coil on the tweeter and the aforementioned MiniDSP on the woofers and mids. The SB's roll off at 5.6Khz 3rd Butterworth without a crossover. That's it. There's nothing else to do. Just let 'em play. I know I'm breaking some rules with this setup but I've tried a bunch of X/overs and throwing complexity at them didn't net me anything. These SB drivers should be on everyone's 2-way 8 inch bucket list.
