    Thats what i figured. Whats a good driver to use in a smaller size box with low tuning that doesnt take a lot of power to drive?

    12" should be OK, my spl requirement isnt high. Maybe 100-110 max.

    oh... medium size room with openings. Maybe 500 ft^2 + open rooms.

    I also thought about IB design but dont know that much about it. Could be a possibility.

    There's no such thing, that would defy the laws of physics.

    "Hoffman's Iron law", you can choose and control any 2 of the 3 following performance parameters, the 3rd one you can't control.

    1)Fs
    2)box size
    3)efficiency

    I have enough power for most drivers, but Im talking about a driver that doesnt require 1000-2000 Watts. I can give it 450W. Right now I have a tempest in a 175 liter tube and its more than enough for me, however I would love to get similar results from 1/2 the size if possible.
