i have an ampeg b2re head rated at 450W @ 4 ohms, 250W @ 8 ohms and a gk 1x15 cab rated for 200W. i have a very basic knowledge of amps and was wondering what would be a good match for another cab. ive been looking on craigslist for a 4x10 but im not sure what wattage i would need to have it fit this rig.

I use an Ampeg SVT-410HLF which is a 4x10 rated at 500w, 4ohms, and have been pretty happy with it (except for lugging the thing around). I don't think you'd be able to use the 1x15 with it, though (not 100% sure on that).

If it's not cranked all the way up, you should be fine with the 1x15.

It would still be safe to get a higher rated cab.

I use a 2x10 and 1x15 handmade by a company called Dr Bass. They are great cabs. They are both 8 ohm cabs so together they are 4 ohms and I get the maximum output from my amp. What is the ohmage of your GK?

The 1x15 should probably go.

ill check on the 1x15

the person who owned it before me used it with a hartke 1x15 and 4x10 so i thought it would be ok. i found an ampeg 4x10 rated at 500W on craigslist, would this be the best match?

this is all my gear, I wanted to make sure I wasn't over powering/under powering my cabs

cabs-4x10 cab handles 400 watts and my 1x15 handles 200 watts

head-ampeg br2e head is rated at 450W at 4 ohms, 250W at 8 ohms

What are the impedances on the cabs? Me thinks you need higher power/matched cabs.

the 4x10 is at 8 ohms and the 1x15 is at 4 ohms

I'd pick up a 1x15 that runs at 8 ohms and can handle around the same wattage as the 4x10. That way you'll be running the head at full power into cabs that can handle it.

ill look around for one, thanks for the advice!

Oh yeah? Well I use an ampeg b2-5 X 23 /2re Ultra head rated at 350W of 50 mega tons @ 4 ohms, 250W = MC 2 @ the outer rim at 88 ohms and an EMP of 56.0025 megahetrz compliant with 56-D/5 OMGZ and 54 LULZ with a gk 16x1,000 cab rated for level 355 warp speed over Quadrant: Alpha Omega.

I have that but with a cupholder.

Is it the Strike force ultra cup holder or the series 1 Deathstrike soda sipper?
