ok, im opening up this can o worms again. feel free to add your 2 cents, but please explain your 2 cents too. music and HT are getting closer to 50/50 from mostly HT. my room is about(from memory) 12x20x7. im using BB6pro and here what i have so far:
Vb=10 ft3
Fb=16 Hz
1 6" vent @ 21"
modeled input power @ 500 W seperate coils
F3=~25.5 Hz
F6=~16 Hz
GD=< 19 msec @ 20 Hz
VV=< 20 m/sec from 14 Hz and up
its got about a 2dB/oct slope in a BW from ~16 to ~50 Hz
i also tried Fb @ 17-18 Hz that resulted in the slight expected changes in GD and output. btw, BB6 suggests 18 Hz
now to the questions i have:
1.what are the pros and cons of seperating the coils?
2.is group delay really noticable
