This isn't a tube amp question since i use an H&H IC100S solid state head with and H&H 212DC 2x12" dual concentric PA cab.
firstly, ever since i've had the cab one of the cones has had an annoying buzz, practically a rattle that occurs when the cab is anywhere near a bass-heavy signal, either played through it directly or even through vibration from a nearby bass amp. The cone has no visible faults and delivers a high volume but it just rattles all the time, so recently i picked up a replacement cone (of the same kind, taken from the same model of cab) and swapped it in for the rattly one. Rattle problem solved. However, the speaker is definitely quieter now (such that i now have to crank the amp nearly half-way to match the volume i used to get at about a quarter/third-ish way) and is definitely shyer on the low-end than it was. Just to make sure i wasn't imagining it i swapped the old one back in, definitely louder and more bassy, but also very rattly. So i decided to stick with the new cone, but as my amp now has to be cranked harder it's actually starting to distort at a volume at which it was previously crystal clear.
So here are my questions...
1) Could it be that there are some components in the amp head i could replace (without knowing a hell of a lot on the subject i'm thinking capacitors) that would allow it to provide enough power to this new speaker without the sound breaking up?
2) currently the 2 speakers in the cab are wired in series, the cab has 2 inputs on the back and the head has 2 outputs on the back. i'm wondering what would happen if i re-wired the cab so each speaker was separate with its own input and i connected it to the amp with 2 cables. would it make a blind bit of difference?
thanks.
