Recently i have been busting my cones in my speakers.
In about Feburary i joined a band that requires distortion (also 5 string heavy distortion) and found after i a little while with them my speaker was distorting when playing 'normal' bass.
I assumed it was just because i've had the speaker for about 4 years - time to die....

So i went to my spare 15" & used that.
Just the other day i realised the EXACT same thing. (Changed over period, maybe a month.....)

My rig is:
Gallien-Krueger 800RB
EV 15" 4 OHM

* I don't 'push it', only playing at about 4-5 on the volume
* Haven't had any power surges or big pops etc..
* I never bi-amp it, only ever use the 4ohm 15"

So now i'm wondering, could it be the distortion? Are 15"s 'not meant for distortion'?

I notice Trevor Dunn uses (in Fantomas) 8 x 10" & Fred Frith used 4 x 10" (Naked City)
(seeing i'm playing similar stuff to what they play)
i've also seen in other metal bands, the guys using 10"s.....

Anyway, so i will get this fixed & when i get it all back, maybe try splitting it,
adding a 2 x 10" 8ohm cabinet on that i have.

Should i get all 10"s? like 4x10 or something?

Recommendations, advice, anything would be great! thanks.

Is your bass active (active pre-amp)? Try changing your battery and see what happens.

Try lowering the level on your distortion effect- you might be overdriving your preamp and in turn overdriving the poweramp.
