simon1964 Posted February 1, 2008 Share Posted February 1, 2008 (edited) I confess to be completely ignorant on these matters, so could do with some advice! I mainly use a Mark Bass 1x15 combo for gigging. I have an old Ashdown MAG 2x10 cab sitting around never getting used, and was wondering whether I could use that as an extension cab? Problem is, the combo is rated 500w @ 4 ohms, and 300w @ 8 ohms (and according to the Mark Bass website has an impedence of 8 ohms). The Ashdown cab is 200w, 8ohms. Can I safely use the Ashdown cab, or am I going to cause damage to the cab, amp, or both?! I'm sure its a bloody stupid question, but as I say, I am completely ignorant in these matters, so thanks in advance!

DirkThrust Posted February 1, 2008 Share Posted February 1, 2008 Don't worry it's not a stupid question. So if the internal speaker of the MB is 8 ohms the amp will put out a maximum of 300 watts into just the internal speaker. Add the Ashdown then the combo amp is connected to two 8 ohm speakers in parallel, so it will see a nominal load of 4 ohms and deliver a maximum of 250 watts to each. Even though the Ashdown is only rated at 200 watts it should be fine. Quote Link to comment Share on other sites More sharing options...
