Thanks for the suggestions!
I hadn't considered replacing just the foam....but my next round of questions would have been along the lines of "Now how do you pick a replacement driver that won't be 3dB less efficient (and therefore "quieter") than the original", etc... I guess if I just replace the foam, I don't have to worry about driver specs!
The Design Acoustics "Point Source" series sounded pretty good. They were relatively deep cabinets with a comparitively small front baffle with the idea of providing needed internal volume with a "near" placement of woofer to tweeter so as to be closer to a "point source" design. I'm impressed with the internals now that I took a driver out.
I'm looking for something for my workshop and I was thinking....don't laugh.... about these
simply because the two overriding factors are "inexpensive" and "louder than a woodshop".
OK, ok. I asked
you not to laugh!
