I will be getting my modded peavey rockmaster tomorrow in the mail and i am planning on biamping using a stereo power amp with a 2x12 and 1x15 cab.
More specifically it would be like this:

Guitar > Peavey Rockmaster w/ parametric EQ in loop > BBE X3 crossover > Rocktron Velocity 300 > cabs

I have never done this before so i want to know what frequency would be a good starting point for the crossover. Speakers are a 2x12 earcandy buzzbomb cab and an ampeg 115 SVT classic cab. Thanks in advance for the help

i´d say about 350 Hz, just for a good starting point :P

If you cut mids at all, as most folks do, from a little bit to extreme scooping. I would put the crossover point at the lowest mid Freq. so as to have minimal crosstalk/phase cancellation. I've noticed in PA mains certain sounds close to the Xover point (usually 2.5k) don't sound as good as freq.'s 150Hz to either side of this point. I would center the Xover point at 600-800Hz and tune the Eq to cut this same freq.

Just out of curiosity, why are you going with a bi-amped setup?

I've considered this more than a few times, but the practicality of doing this in a live situation isn't great, unless you're planning on running your guitar signal direct and using the bi-amped rig for stage monitoring only. (Bass players that use bi-amped rigs are usually sending their signal direct to the PA, and their rigs are for stage monitoring only.)

Otherwise, you'd potentially have to mic one of your 12s AND your 15 in order to get the full spectrum of sound.

I think a bi-amped setup would sound awesome, but it's just the process of getting that sound out to a PA that might be a challenge. You'd sound awesome onstage, but not necessarily so hot out front.

actually I want the biamped setup for our reharsal room and also for recording.....since i play in a very athmospheric/dark sounding death metal band i wanted the 15 speaker to add to the ambience...our sound is sometimes doomy... not necesarily punchy fast sound ......since we are only 3 guys(bass/vocals,guitar and drummer) i guess it helps in sounding fuller...we'll see once i have the setup ready .....

For live i will just use my head and my baritone and ask the audio guys to make the bass sound really big and some reverb also for vocals. Also about cutting mids.....i usually boost them..no cut for me...at least not in this band

Most clubs that are willing to do death metal around my neck of the woods don't line in or mic up shit except for the vocals and the kick. The very few clubs that do mic up guitars would have no problem slappin' another 57 in front of the 15". These clubs have subs so getting the tone to the crowd would work just fine.

As for boosting the mids, find the lowest Db. freq. point and cut that. 350 would be, like the other dude said, a good place to start.
