Replacing 2 12in Speakers

Discussion in 'Amps and Cabs [BG]' started by deadinameadow, May 27, 2018.

  1. How's it going my fellow bassists? So I'm currently using a vintage Kasino Concert Con-B amp and 212 cabinet that matches. 1 of my 12s is blown so my cab isn't running as great as I'd like it to.
    I'm planning on replacing both speakers with 2 Eminence Legend BP122 speakers.
    My question is, will pairing these 2 speakers (8 ohms each, 250w rms each) work well with my head? (which says it operates at 125w at 4 ohms) This won't be enough power to ruin the speakers I'm assuming, is that right? Do both of these speakers combined equal 500w rms @ 4ohms? Is this what they mean by headroom?
    **note I play a 5 string bass in a fast metal band and drop A is our lowest tuning so far, does anybody have experience with these speakers and do you think they would perform well under my brutal sounding circumstances? Thanks everyone! \m/
  2. Also my cabinet is ported, a somewhat oval shaped air hole along the bottom of the cab. This thing is a beast for a 212.
    I'm not sure what speaker would be best for low tunings and picking up the low frequencies but also allowing my highs to cut thru. This Eminence speaker is in my price range and seems good but I don't have the technical expertise or resources to test it out before ordering. Thanks again!
  3. @AstroSonic I heard you're good a selecting replacement speakers if you could offer some advice? Thank you

    That Eminence speaker is geared more towards sealed boxes, so there may be better choices.

    If you could measure and post the internal dimensions of the box and the port dimensions (including depth or if it’s just the baffle, then the baffle thickness), I or someone else could run the numbers to see what would work best in that price range. If you’re so inclined, some modification of the port could open up other options, too.

    Be careful using the cab with just one speaker. Because it’s now in a larger (relatively) air space, it’ll bottom out much sooner.
