Step 470Hz-800Hz: JBL 2225H Woofers in Bass Reflex Boxes
I used some of the salvage money to buy a pair of JBL 2225H woofers salvaged from a closed-down movie theater.
I used WinISD to design some 3ft3 bass-reflex boxes tuned to 40Hz, and then manipulated the cabinet dimensions (keeping the volume constant) so the boxes would fit inside the built-in cabinets in my office (if I un-mounted the cabinet doors).
The 2225 data sheet specifies a "highest recommended crossover point" of 1,200Hz, so these should cover my 70-800Hz range:
30-70Hz: Subwoofer
80Hz-800Hz: JBL 2225H Bass Reflex
800-8,000Hz: Altecs/Azuras
8,000-20,000Hz: FT17H's
I'll detail the cabinet build in the next few slides.
