ive got a hartke 2500 combo and want to get a extension cab for it not sure what ohms it is??i used to have a 400w calsbro 8ohm cab i used to use on it and it blasted out a good un,i was thinking of a vx210 cab which is 200w 8ohms or peavey tvx210 175@8ohms,or might go for a small 15" mag/laney ritcher 15"just im not giging much now and need to downsize on a budget! :-(

According to the manual the minimum impedance is 4 ohms, which the internal speakers are already running at. You shouldn't add another cab to that set up.

??why would there be a 2nd speaker exstention jack output port in the back of the amp if you can't add?

I found that a little odd as well, but the manual is pretty unequivocal.

[quote]"The VX2510 & VX2515 combos feature the HA2500 amplifier providing 250 watts of power to the built-in 2-way bass speaker system.

...

Rated power - 250 watts @ 4 ohms
Vx2510 Speaker System Impedance (Ohms) - 4 Ohms Impedance"[/quote]


They probably found it cheaper to put the 2500 head in to the combo as is rather than modify the speaker outputs for combo use,
