Sorry, my last comment about slaving into a combo was meant to be tongue-in-cheek.... Thanks for your advice guys. If nothing else, you've saved me cooking my amp!!!

Thanks both.... Now I understand the importance of matching up the impedance. Should have remembered ohm's law from physics class at school, but that we 20 years ago What put me off going for a 6 x 10 or 8 x 10 is the physical size... My band is displaced across Aberdeenshire, so we all usually have to drive ourselves to gigs. Trying to get an Ampeg wardrobe into a 2-door Ford Focus is not fun - but I think I could have managed the 4 x 10 plus an extra cabinet.... Anyway at least I know that I need to think of something else. Perhaps a crude idea would be to buy an Ampeg BA300, and slave into it. But I have no idea how (bad) that would sound.

Assuming that your current cab is 8 ohms and the minimum load for the SVT is 4 ohms then you can add any cab providing it's 8 ohms. If you like the sound you get at the moment then add another the same. A lot of people would add a 15 under it but it won't necesarily go any lower than your 4x10 and the end result may sound considerably different to the sound you get now. Only you can decide if you like it or not[/quote] Hi Andy. Thanks for the quick reply. My cab is 4 ohms. Since you assumed its 8 ohms, does this change what you are suggesting? For info, the SVT450 head delivers 450W RMS @ 4 ohms , and 275W RMS @ 8 ohms

Hi everyone. I'm newon this forum, and looking for some advice.... I'm currently using an Ampeg SVT450H head with a SVT410HLF cab. It's perfectly adequate for most of the smaller gigs, but now and again we play some slightly bigger places and I push it to the limits. It would be really good if I could have another cabinet which I could add-in for the bigger gigs, to move some more air... However I have no idea if this is possible as I know very little about matching up impedances, power ratings etc. The cabinet has 2 speakons, but does this mean I can add another cab? And if so, what can I add? Grateful for any advice you guys can provide. Thanks in advance....
