tommania Posted December 9, 2014 Share Posted December 9, 2014 Hi guys, I recently picked up this 1981 Marshall 2x15" 200w cab at 16ohms. The reason I bought it was because I got it at a steal of £35! It sounds gnarly, got a really nice tone for what I'm going for and it's loud as hell. However my problem is I think my head will probably blow it. I am using the Ashdown ABM 900 Evo III which is 575w+575w at 4ohms. I notice that if I have my input and output knobs any higher than both at 12oclock my dial goes insane. That seems loud enough for me though, but is this likely to damage the cab? If I was to hook up another cab using the same side as the head would this ease the amount of power going into the cab? Thanks, Tom Quote Link to comment Share on other sites More sharing options...
cheddatom Posted December 9, 2014 Share Posted December 9, 2014 Are you the Tom I think you are? The minimum load your amp wants to see is 4 ohms. Running at 16ohms will certainly compromise it's ability to go loud, but shouldn't damage it. Quote Link to comment Share on other sites More sharing options...

Me and Ant are sharing it! Just worried about pushing it and damaging it 'cause my head is a bit of a monster! I'll bring it to the studio and you'll have to try it out![/font] Quote Link to comment Share on other sites More sharing options...
cheddatom Posted December 9, 2014 Share Posted December 9, 2014 just don't have it deafeningly loud and it'll be fine, I'm sure! But yeh, if you like the cab, your head is overkill. Let me know when you'll be down there next, let's give it a thrash Quote Link to comment Share on other sites More sharing options...
3below Posted December 9, 2014 Share Posted December 9, 2014 16 Ohms cab will help reduce power delivered by head, thus lessening chances of destruction. Take a look at most solid state specifications - max power usually at 4 or 2 ohms, significantly less power at 16 ohms. Speakers at 200W thermal power rating is not a lot in this day and age in comparison to the potential output of your head at 16 ohns. If it starts 'farting' or making other bad noises adjust the loud knob downwards. Quote Link to comment Share on other sites More sharing options...
