Thanks for the nice comments, guys.
These are excellent sounding speakers. They don’t have the deepest bass in the world, but they go deep enough for most music. Those woofers (they’re actually mid-woofers), or their descendants, can be found in very expensive commercial designs.
When I built my
other set of speakers, I intended for them to replace these. The new ones do have better-defined, deeper bass, but they don’t convey the emotional nuances of vocals and other instruments as well as these.
RCCinNC, you should just do it. There’s nothing like listening to speakers you’ve built yourself. I’ve had aspirations of learning how to design my own, but I’ve never actually tried. It can be an expensive hobby.
