Hello,

for normal levels, "10 a clock", there is no need for crossover,

but for the bass you need a active modul, to get the SPL,
if you take a sub modul, why not with a sat crossover,
than you get the highest SPL.

this is one of my best solutions, for B200.

sorry what you mean by a "sat crossover" ?

I was wondering about this solution to get good bass with a lowther unit I have.

In this regard, I noticed your system SCHALMEI + ALPHORN.

Does I need a crossover to integrate the schalmei with the alphorn ?

Thanks !

sat crossover of better Submoduls are cancled the power for the sat at 80-140 Hz, min. 6 better 12 dB, you get more SPL because the driver must not move for the lowest oktave.

if you use no B200 the best solution is the SAXOPHON,
bass soundstage dynamik, no submodul

Hm, what kind of enclosure is that in the lower b200 image? How does the above SAT horn achieve a consistent spl down to 100hz? Now that I have ordered parts for a filter I'm having second (third) thoughts. A more mechanical solution would be so much more satisfying. I work on electromechanical equipment for a "living" and I always find good, sound mechanical engineering at the heart of the best designs

Hello,
i didnīt get what you want?
look my HP, you see measurements, plans, feedback,

do you ask for the ALPHORN?
look bass horns,
and double horns.

I have been playing with a completed line level filter that was posted by Geoff H. The end result is a 6db reduction in output above ~1200hz with a small bypass cap that helps to restore the upper octave. The sound is much mellower as a result, the downside is you forfeit the b200's efficiency (as expected) and some of the nuances and air seem to diminish. Next step for me is to work out a LL filter that only attenuates the B200's response by 3db.
