"I have a "poor man's version" of those, which means the standard (non-modified) BMS 4592 in a large 200 Hz horn. I many respects mine are good too, but I have trouble getting rid of some harshness in the treble, which I am sure you do not have. I really regret that I didn't wait and saved up for the Orphean..."Bert did a lot of good work developing the Orpheans. He has a phase plug in there for starters. He also has a carefully designed crossover. To help you there you might want to get the tweeter crossover capacitor changed to an oil type. That might help.

Hi Kurt,Thanks for the answer and for the tip regarding paper/oil caps. Happy listening, I am sure the Orpheans do sound great!
of the passive one developed by Bert ?
The passive crossover is of very high quality, and you can even opt for silver foil caps at a $1K or so premium. The crossover is a first order type designed with all the equalization, etc. built in. An active crossover and bi-amping (or tri-amping even with bass bins) is there as a possibility if you throw out all the passive crossover components yourself, and then you have to engineer a crossover yourself.Maybe Bert can sell you one without the built-in crossover. I just don't see the advantage myself. Even the high end cap choice is cheaper than adding another high quality amp and passive crossover. One good amp with one voice from 220 Hz - 20 KHz seems right for this speaker, and another SS amp for the bass bins. That's just my opinion, of course.
