(a guess at taste in the 21st century from car audio subs = "whats a cello?"8 cubic foot seems like a good size for 50Hz and reasonably high sensivity and potential to lift and ship -?
I have a CH250 10" on cardboard open baffle - its gets into trouble on drum tracks with my almost-dead ears at 7 inches - not even a headphone - It should play cello by low-end specs but can't.
long live good horn art (az if I practiced that...)
Follow Ups:
floor and wall 100 watts is all the 6 can take
COOL-----can a LAB12 be clamped to K-slot BLH and work well at high input power to make a nice little sub?
I think it may be too big...try a simulation
this was a guestimate wiht red = Lab12 - does the entry look ballpark?
yes except for the spl. notice how excursion goes down with rear chamber
drivers input set at 20v - your BLH as FLH makes a pretty graph with LAB12. Does the 88 sq.cm. entry into expansion present any problem at high power?btw -why did AJ show a Bose cannon type to look better with driver 1/3 way down pipe than 1/4 down?
