Head+cabin question

Mr M · #1 06-23-2010, 02:36 PM

Short question.
Yes you are right, I know nothing about amplifiers.
I have a MarkBass Little Mark II head (500W @ 4 Ohm). I've bought SWR Goliath Jr III cabin, 4 ohm (it is 350W RMS).
If I connect the head to the cabin, is there a risk that I damage the cabin?

Goliath Jr III is a 2x10", if I add a 1x15", how the new 15" should be (to be used with LMII)? 4 ohm 200W for example?

Can you use it. Yes, but you will not want to crank it. The amp can and will damage your speakers. If you crank it, it will put all 500 watts into a cabinet rated at 350 watts. If you add another 15" cabinet rated at 4 ohms, then you need an amp rated at 2 ohms. Best scenario would be two 8 ohm cabinets which would take the load to 4 ohms for both. Looks in the Faqs, there is sticky for amps.

Thanks for the reply and not killing me with such stupid question.

I'd like to ask also, is there any way to connect an additional cab to this combo (as the head is 4 Ohm and not 2 ohm) or not.

cant. the head is 4 ohms... your options are

1. 2 8 ohm cabs
2.1 8 ohm cab
3.1 4 ohm cab
