4x10/1x15 stack: ohms question

    I've noticed that many brands have 4x10s with power ratings almost double that of their 1x15 cabs. For example, aguilar, with a 700 watt 4x10 and a 400 watt 1x15. For situations like these, what's the best solution? If a DB750 was hooked up to these cabs, 2 8 ohm cabs would receive 375 watts each, underpowering the 4x10. 2 4 ohm cabs would receive about 487.5 watts each, possibly overpowering the 1x15. a 4 ohm 4x10 and 8 ohm 1x15 would receive some where in the vicinity of 525-550 watts and 325-350 watts, respectively, but the 1x15 would be underpowered compared to the 4x10 (right?) Or maybe not. Hit me back with opinions.

    get the 2 cabs in the same impedance. a 1x15 is already moving just a little more than 1/2 the air as a 4x10, and they often have a lower sensitivity. but not so much that you want a 4 ohm 1x15. however, getting an 8 ohm 1x15 and 4 ohm 4x10 would probably result in almost no "noticable sound" coming from the 1x15. contrary to popular opinion, you can't "underpower" a cab. i suggest going with 2 8 ohm cabs.
    however, lots of cats who have used aggie cabs say they get better low end out of two 4x10 cabs. in that case i'd get two 4 ohm 4x10's to use with a 750. and earplugs.

    I'm one of those cats. Let's clarify that its MORE low end with two 410s instead of the 15, but its a DIFFERENT kind of low end that the 15 offers. Quieter for sure, less low end for sure, but the 15 is a different character of low end that some might be searching for.
