ohms cabinet question

[suprstar]

A higher impedance cab is fine, but the higher it is, the quieter it is as well. The lower it is, the louder it'll be, but it will also make your amp run harder and hotter. If you go too low you'll fry your amp. The most common way to lower impedance is to hook up multiple speaker cab's in parallel. Theoretically you could push 4 8ohm cab's with that amp.

If you are only going to use 1 cab, you might be able to rewire the speakers in your cab to 4 or 2 ohms, depending on what speakers are in it and how it's wired now. If the powered mixer is from a reputable company, and it claims to be 2 ohm stable, it probably is.

ok thanks its a peavey powered mixer from 1980.it says one output 2 and both 4 ohms.so it should be fine going to a marshall stereo cabinet.the marshall is confusing because im only using one speaker in a 212.it says in stereo 4 ohms

i have a p.a powered mixer i am using for a amp when i do not want to run my other amps.how can i match the ohms to my 8ohm cabinet.it says minimum load 2 ohms on the p.a.

Its fine, just plug it in.

You can lower the impedance by connecting more speakers in parallel, but there isn't any need to 'match' them.

I wouldn't recommend going as low as 2 ohms though - some amps claim to be able to handle this 'easily' (*cough* Behringer *cough*) but really you wouldn't want to be running it this low for a very long period of time. I've had problems with Behringer EP2500 amps running under 4 ohms load for a few hours, so I hate to think what 2 ohms would do to them!
