    I have a deltabass head which powers 160w at 4ohms and 110w at 8ohms. I have a 8ohm ampeg 2x10" bass cab. i was wondering if there was any way i can somehow pull the whole 160w out of the head without using another 8ohm cabinet

    There used to be some high power audio autotransformers available but I think your cheapest alternative is to recone the speakers in that cab with 8 ohm coils so that the two in parrallel will be 4 ohms. :)

    Reconing won't change the impedance, and I don't know if you can easily replace coils. I think you'd need new speakers.

    It's unlikely to be worth the effort. The difference between 110 and 160 W just isn't that great.

    If volume is your concern, getting another 8 ohm cab would probably be the best thing you could do without buying another amp. Not so much because of the extra 50 W, which as I said wouldn't make that huge a difference, but because the extra speaker would immediately bump up your acoustic output *even with the same power*. is pretty cheap. Haven't tried them myself, but a lot of folks here swear by them.

    Dude, the cones are attached to the coils. When you recone, you ALWAYS end up with new coils.:rolleyes:

    Now, while you're reconing you should make sure you get the square coils that won't blow instantly on clipping like the round ones do.;)

    I'm a bit confused by this picture from the avatar site. Towards the right side of the pic it shows two negatives and the two positives connecting to form one before you plug it back into the amp. Do you use a 1/4" y adapter for that? can a y adapter handle that much wattage?

    They're already wired that way internally. The diagrams are just showing the options you have for configuring 4, 8 or 16 ohm speakers to give the desired impeadance to the cabinet. You COULD wire 4 4 ohm speakers in parallel, but not many amps will drive a 1 ohm load at max power, and you'd lose a lot of power wiring 4 16 ohm speakers in series for 64 ohms.

    Just tell him you want an 8 ohm cabinet, or a 4 ohm cabinet.

    not usually, but it's possible if the speaker in question was also available in an 8 ohm version. You can request it be reconed using the 8 ohm recone kit.
