Paralleled outs on an amp

[PeaveyPippin]

I have a Peavey Nitrobass 450 2ohm, 300 4ohm, and 170 8ohm head that I use with a Peavey 2x10 tvx that can handle 175 rms @ 4ohm. I'm wondering if it's possible to add a 15 under it to give it a bit more bottom, but the Peavey 1X15 tvx is 250 @ 8ohm. Is that even possible or would I blow something up and waste a bunch of money in the process?

So the 2 X 10 is a 4 ohm enclosure and the 1 X 15 is an 8 ohm cab? Should be listed on the back of each. Let us know.

Yes the 2x10 is 4ohm and the 1x15 is 8ohm.

Not a problem

[PeaveyPippin]

Sweet, thanks. I've never understood ohms and watts. They will ever allude me.

Yes, you can do it since your amp is 2ohm stable. 4ohm + 8ohm = 2.67ohms. Close enough to get most of the 450w split evenly between each individual speaker.

Somebody refresh my memory....what would be the power distribution betweenst the two?.

2/3 to the 4ohm & 1/3 to the 8ohm? or would it be 50/50?

[PeaveyPippin]

Even if it is 50/50 that still seems like it's be decent power to each yes? 225 watts to each is pretty near the butter zone for both cabs yeah?

It's 2/3 to 1/3 distribution, and I would guess the amp would make around 400 watts at a 2.67 ohm load. You'll be be fine.

Sorry to dredge this up again, but I'm still pretty much an idiot when it comes to this stuff.

I found out that the 115BVX comes in a 4ohm version. Would it be better to push a 2ohm (that is what I get from 2 4ohm cabs right?) load with more watts to my 15?

[RickenBoogie]

I would, since a 2x10 and a 1x15 are fairly equal in the ampunt of sound they produce. A matched pair, (2 4 ohm cabs) would divide the amp's power equally between both cabs. Yup, that's what I'd do.
