I have been considering building a single cabinet using the plan for a 130a bass, 175DLH and N1200 crossover in a 16 ohm system in my garage. I have an old Fisher 90X tuner, a Heath mono preamp and E-bay (where I expect to find a tube Mono power amp).

I have a pair of 130a JBLs in excellent condition but hate sending them to exile in the garage. I do, however have a 16 ohm 2220b bass speaker.

Looking over specs for the 130a, 16ohm, and the 2220b, I cannot see any difference except for the number. The 2220 being the "Pro" equivalent to the 130a.

Am I correct in my reasoning?
