Due to circumstances way out of my control (wife changed her mind), I don't think I'll get to fill in the area around my fireplace and go with the dual Tempest IB project I had been longing for. But, I'm still going to make a new sub in the next couple of months. I'm toying with the idea of a noisy coffee table. I should be able to go 8 ft3 or so I would think. Has anyone done this, and do you have pictures? I think a single ported Tempest design would be good. Maybe a bottom firing driver with ports on each end? What do the experts think?
