Combining 410 (4ohm) with a 115 (8ohm)

    All,

    a 410 + 115 is a combination that I think would suit me pretty well, I'm trying to test it (haven't so far) with some friend's rig.

    Putting in parallel a 4 Ohm 410 with a 8 Ohm 115 will make a load of 2.7 Ohm if I'm not mistaken which will be fine with my DB750. Nevertheless if you look at how the power will be distributed, much will go to 410 vs. 115 (because the latter has higher impedance), right?

    If so, and considering that usually 115s have lower sensitivity than a 410s, will the resulting combination of speakers play fine considering just the Ohm and sensitivity factor or it's more reccomendable to equal the Ohms of the speakers combined (most of 410s are available also at 8Ohm, or I think at least the EBS neo 115 is available at 4 Ohms).

    Thanks for shedding a light on this!

    Should work out pretty well, I'd think.

    My 1x15 is 8 ohm and 103 db@1w/1m.
    My 2x12 is 4 ohm and 101 db@1w/1m.

    Pretty good matchup. Sounds great. And the head has been working for years @ 2.67 ohms. No issues whatsoever. If you like the overall sound, you are good to go!

    Right, the 4x10 will get twice the power that the 1x15 will. That's not a bad thing, as the average 1x15 has less power handling and output capability than the average 4x10. OTOH, that being the case, you might want to rethink why you'd want to add a 1x15 to a 4x10. Another 4 ohm 4x10 will work better, and an 8 ohm 2x10 probably just as good.
