anyone here work up a good crossover for new Beta 10CX?

[freddi]

the newer version of Beta10cx looks like it could sound better than the first version - has anyone here gone beyond a generic crossover for Beta 10CX?

thanks ZilchLab - so the following circuit with 10cx & 220HF is "it" (?) - in a Karlson the high frequency lobe is tilted up by baffle angle so hotness on axis can be a good thing - also I don't believe there's much baffle step compensation needed - if I can dig out a coax I'll try to wire one up - if it goes in a box then L2= like 2-3.5mH depending upon cabinet width (?) -oh did anyone try the little titanium Eminence compression driver?

We used the EconoWave driver on the EconoWave crossover, yes.

It's your job to try any drivers other than the half-dozen we tested....

despite the two dips, APT50 sounds "good" on C12cx cast frame Eminence and its cousins with their funky ol' rectangular horn (that Eminence {and P_Audio} horn reminds me of EV's ancient CDP HF horn). I measured the two dips 8 or more years ago and IIRC (?), showed on every horn and on Karlson -tube.

High Efficiency Speaker Asylum: anyone see dips on APT50? by freddyi

I eq-ed Beta10cx's HF with a cap across a series pad resistor - probably not as good as your setup. EM's first Beta10cx and B102 had lackluster mids poked back into a Karlson-type coupler - first B102 made an ok fake Druid - -Qts spec on both went up when they introduced the improved surround.

-oh-- need to buy some of your xover boards - re:220 - if one wants to share between threaded coax and bolt-on QSC waveguide - is it best to get the bolt-on version? Ti205 came with a nice cast metal adaptor for thread-on.

have any affordable waveguide popped up suitable to do Econowave with 15" woofer? - DDS has a 24" waveguide but its too large for Gedde's style application with 15"

thanks for your time and help
