Peavey 12" stage monitor used as a cabinet?

Im looking at using a spare 12" stage monitor we have at the church for a cabinet but, can that be done? I am putting it to a micro terror and the speaker itself is going to be in an isolation box under the stage.

No reason not to try it as long as the impedance matches ... might respond well enough with an EQ tweak to the head as indicated ...let us know how it goes

It'll work. As to whether it sounds good or not, impossible to tell. I'm curious to know how it sounds.

Guitar amps usually don't sound very good pushing a fill-range cab. I suspect the controls on the Micro won't be able to compensate enough but it's worth a try. The thing about extreme tone control settings is that they'll affect the character of your gain too.

Do you have access to a graphic EQ? If the Micro has an effects loop, that's likely to be a better option.

I'd seriously consider disconnecting the horn driver.
 
Re: Peavey 12" stage monitor used as a cabinet?

Just think of the horn (well it's most likely a horn) as a tweeter. It handles frequencies from about 2000-15,000 hertz in a basic two way stage speaker. The highest fundamental electric guitar frequency is about 1300 hz ...that would be high E. Now guitar does have harmonics that extend several octaves higher than that but the nature of your standard 10-12 inch guitar speaker is such that the sounds above 2000 hz are naturally attenuated and that's a good thing. Too many highs will sound shrill and unpleasant especially if you're using a distorted tone.

Now if you're going to stick it in an iso cab and mic the woofer really close so that the mic doesn't hear much of the horn you might be alright. But if it seems to work OK but just sounds shrill...lose the horn.

Hadn't realized modding the cab was an option. In that case, disconnecting the horn and crossover would be the best way to go. If you simply disconnect the horn, you'll lose all of the highs, and even though speakers do naturally roll off a lot of the high end, I don't think the sound would be great if you were hearing only tones below the crossover frequency. However, with the amp hooked directly to the speaker the sound might be pretty good- depending on the quality of the 12". Years ago I had a floor wedge loaded with an EVM 12" to use instead of my 4x12 when the stages were very small. It sounded quite nice actually, not too much of a sacrifice in terms of tone.

If modding the monitor is not an option, see if there's a knob for controlling the horn level- this used to be pretty common but I don't know whether it still is. Some speakers may still have it. If there is one and you can spend some time with it, you could experiment with rolling off the horn until your tone sounds more natural to your ear, then put the monitor out of the way once you've found a decent balance.

Not much to add, but I would disconnect the horn. It could be a compression driver or a piezoelectric tweeter, but it will add enough top end that for electric guitar, it won't sound natural.

But leave it wired in for an acoustic guitar...you want that top-end to give you a natural tone. And, if you are using a pedal rig with speaker emulation, you might find that it will work best with the tweeter connected.

Sounds like a cool idea. Let us know how it works out. Btw, my 2-cents worth is leave the tweeter connected if you're mainly going to do low volume. Maybe disconnect if you go full balls-to-the-wall. Maybe. :dunno:
 
Re: Peavey 12" stage monitor used as a cabinet?

would disconnecting the tweeter and / or crossover mess with the total impedance of the cab?
