Astoundingly, the bass on my new speakers is opening up. The two 7" woofers don't have a great deal of linear excursion and I thought that this was limiting the low end (< 80Hz). However, today for some reason the base is as clear as a bell; perhaps a little too 'in your face'. What surprised me (but on reflection shouldn't have) is that with playing, the rubber suspension will soften a little and the impose slightly less damping. Perhaps running a 20Hz sine though them at fairly high power yesterday had something to do with it. It may not be an accurate sound, but as a bass player, hearing the bass lines so well defined is nice.
So now I'll have to repeat all my measurements for the empirically-based crossovers (the ones I'm using at the moment were cobbled together from some components I bought based on the published performance of the drivers). The good news is that I didn't spend $80 mainly on coils I may not need. Coils are really pricey. I'm probably going to buy some enamel coated wire and wind my own.
