Really a guitar amp question, but... I figure guitar forum people are useless at caring at this level anyway. So in my recent love for all things Class D, I've converted to Class D on guitar as well, and bought a Quilter MicroPro 12 HD, which is basically a 100W amp connected to a closed back 12" with a Celestion BN12-300S bass driver in it. I really liked it. Then I bought a MicroPro 10" to kind of complement it, which normally has a guitar speaker. Didn't like the sound. So I bought a Celestion TN1020 pressed steel neodymium bass/midrange driver on a whim and stuck it in that combo. I think I struck gold or something because this sounds really good! In fact, it is sounding better than the 12" speaker for me. So what do I do now? Going back and forth, it seems like the TN1020 sounds bigger, more balanced, less boxy, than the BN12-300S loaded box, which, until I tried the TN1020, sounded completely fine but now sounds strident and boxy. Both cabinets are exactly the same size (yeah, I know, but it's a guitar amp), and I've measured the internal dimensions: 15 7/8" wide, 12 3/4" tall, 5 1/8" deep. It's a completely sealed cabinet. Celestion TN1020: TN1020 Celestion BN12-300S: BN12-300S (8) I think it's too cramped in there for a baffle converter (front loaded cabinet) so my only options are to ditch the 12" combo, have it modified, or find another 12" speaker (preferably neodymium). Is it possible for me to try to get what I'm getting from one 10" speaker in a 12" speaker without trying a million drivers out? ORRRR... do I just live with the 12"? I mean, it was perfectly usable before, gigged with it plenty. It didn't just become crap overnight. (Lastly, do you think it's safe to play keyboards or the occasional bass through this amp when loaded with these speakers?) Thanks.
