In my other hobby I'm a bass player. I do usually at least one gig a week. Enclosure design is a big deal and the subject of all sorts of voodoo and science, especially for bass frequencies. There's a tradeoff between efficiency and low end response, between volume and efficiency. The usual argument bass players get is "you can have any two of the following--small size, volume and low frequency responseâ€"but you can never have all three at once." Cbinets designed for good bass response are often vented or ported; the ports are often tuned.
I thought a lot about the enclosure when I stuck a sall scale railways soundcard in an LGB mogul, and then I thoguht "probably there's some guy out there who has redesigned a cr to be the perfect speaker enclosure, except it wouldnt be perfect because different people want different things...
I just closed it up and ran it!
