    Looking for some knowledge on this one,

    I like the sound of 12s,
    I like the sound of my sealed 8x10, guitar cabs are usually sealed right? Besides open back ones of course.

    Could I buy lets say a empty guitar 4x12 cab, and 4 Carvin 12 Bass Speakers...I don't know anything about crossovers and that junk...need some help on this one..

    It might be possible under a couple of conditions. First, the box needs to have enough volume to work with the drivers. Second, it will probably be necessary to add a port in order to use off-the-shelf drivers.

    Before ordering stuff, I strongly recommend playing around with WinISD, and learning a bit about speaker design. What you are up against is a design project, albeit working within the constraints of available drivers and boxes.

    Some research and modeling might save you the annoyance of a speaker that doesn't give you what you want.

    A half-stack 4x12 guitar cab is probably too small for four bass 12s.

    I stuffed four EVM-12L in a Kustom guitar cabinet... sounded killer with my old Ric 4003

    This might sound crazy but I like the sound of Marshall 4x12 cabs for bass.
    Deep Purple Machine Head - that's great Ric/marshall/4x12 tone.

    Ampeg V4 (4x12) are guitar cabs and they sound great for bass. I have three of them, one loaded with four neo 2512's, one with original heavy duty (50 watt) Eminence speakers and one with original medium duty (30 watt) speakers. ALL of them sound awesome, but i don't like to push the cab with the 30w speakers too hard. so, yes, i think 4x12 guitar cabs can make great bass cabs. i always liked playing bass thru marshall cabs too (as long as they didn't have greenbacks in them.

    Also a speaker noob, but if he leaves it sealed he can get away with a smaller internal volume, no?

    Might still be small, though

    No. For equal output a sealed cab must be larger than vented. That's why vented cabs dominate the market.
    The best help I can offer is to tell you to go listen to some 4x12s and if you find one you like, buy it. Rolling your own is a bad idea, until and unless you can read this and it actually makes sense to you:
