Using cabs with different efficiency?

    Anyone doing this?
    How does it sound/work?
    Is it better to use a stereo poweramp when the cabs differ more than 3dB SPL?

    I do.
    I use BagEnds

    I have a 4ohm 210
    System Type:
    Full-range, rear vented
    2.9 cubic ft.
    4 Ohms
    Frequency Response:
    40 Hz to 6 kHz ± 6 dB
    (4 pi Steradians)
    100 dB SPL (1W @ 1m)
    Power Handling:
    400 W continuous sine wave
    800 W instantaneous peak

    and an 8ohm 115
    System Type:
    Full-range, front vented with
    removable vent cover 5.1 cubic ft.
    8 Ohms
    Frequency Response:
    40 Hz to 4 kHz ± 6 dB
    (4 pi Steradians)
    103 dB SPL (1W @ 1m)
    Power Handling:
    200 W continuous sine wave
    400 W instantaneous peak

    I always run them stereo. The 115 really does dominate the output though if I keep the channels balanced. I push up the 210 side a bit to get the sound I want.

    I have run them with another cab (8hom 112) paralled with the 115 for a 4ohm load. I just did it for an outdoor gig and the 112 ended up being a bass monitor for the drummer. I still kept it stereo.
