   Hi

My recent project with Beyma 12P80Fe in about 50L reflex + Faital HF144 + LTH 142 would otherwise fit the bill, but active crossover (900Hz fir) only atm.

Only 4dB's of boost was required below 100Hz for decent bass sound in full range mode. Also tried 'em as tops >100Hz with 37Hz tuned 18" TH's.

Have thought making passive crossover option, but the highish power capabilities of beyma bass-mid  sum up to expensive and heavy coils. And lowish xo point leads to more expensive, larger capacitor values.
