Would love to know how the KEFs stack up against the HSU Research CCB-8s I use in my home theater. Really enjoy them.
Send one to Amir for testing.

I'm considering getting a couple more for surrounds in my home theater so that's a possibility. A single would be fairly inexpensive to ship.Send one to Amir for testing.
Some people call as "pseudocoax" loudspeakers where the individual drivers are placed one in front of the other creating usually unwanted edge diffraction and secondary sound sources, in the Sceptres the acoustic centre of the tweeter is actually behind like on a "real coax", but on the other hand its horn is in front of the mid bass driver.Yeah, the best (smoothest response) coaxials currently use smaller drivers. But why do you think the Sceptres are "pseudocoax" in their design? Because it uses a horn-loaded compression tweeter?
How about MEG's RL901K, where the woofer crosses low enough that diffraction is probably inexistent? Genelec seems to call this approximately coaxial.Some people call as "pseudocoax" loudspeakers where the individual drivers are placed one in front of the other creating usually unwanted edge diffraction and secondary sound sources, in the Sceptres the acoustic centre is actually behind like on a "real coax", but on the other hand its horn is in front of the mid bass driver.
Yes and as said all these kind of namings and definitions are just names and not necessarily qualitative descriptor.How about MEG's RL901K, where the woofer crosses low enough that diffraction is probably inexistent? Genelec seems to call this approximately coaxial.

From measurement point of view there is the one I write above, although on the bigger 3-way models like 901/921 only the woofer is partially covered which isn't as big problem due to the only large wavelengths transmitted from it compared to a mid(-woofer) and an the other hand the audibility of those problems is important and to be determined which is almost impossible though as you would be comparing 2 different designs which have also other system differences.Like Me Geithain? I've always wondered if there is a disadvantage to doing the coaxial like that with smaller drivers simply placed in front of bigger ones.

Thank you! Yes I was surprised with the EVO not having anything on that front … I guess the design brief was more around simplicity … matches the target market requirements I would imagine.@Slash86 Your setup is not wrong on paper at all. Think of it this way: for the LS50WII and KC62 combination, KEF recommends a 45hz LPF for the KC62, 5hz lower than yours, and they expect that to be in tandem with a HPF to the LS50s set at 70hz. In that setup the mains are producing less bass than your Metas, and even then KEF suggests setting the KC62 to 45hz. The difference there is small, so it says something positive about your instincts that 50hz sounds about right.
Since you don’t have measurements and you don’t have control over both a HPF and LPF, then trusting your ears is the way to go. If yours tell you to stick to 50hz then don’t change it because it seems like a low number.
As for the plugs, I say give them a try. I would keep it symmetrical so that the phase behavior of the two speakers stays as similar as possible. I’ve tried them asymmetrically in my setup and it didn’t work well for channel balance and optimizing phase with the sub. Others smarter than me will know if they introduce other unwanted problems (distortions, port resonances, etc.).
I’m a little surprised that for the price the Evo 150 doesn’t have even rudimentary crossover settings. As long as they have that advanced display and a sub out, they should be offering the ability to control a HPF and LPF.
you should try to invert sub, not main speakers( mains are in stereo and bass goes over 100Hz).The other thing I was thinking was to invert the cables on one speaker to get some low level frequency cancellation.. but without the ability to make measurement, I thing I’m just opening the door to messing around with everything !
Adding a high pass filter ( around 120 hz) to small speakers with a sub increases the dynamic range of the system dramatically. It also requires 2 subs located next to the mains. That's how my original LS50's are set up.
