I've enjoyed the little box for over a year, but been bothered by the overly middy nature. The EQ always had the bass bumped, mids at 9:00 and that sounded pretty good, but it still never sounded smooth to me. About three years ago, I built one of these little puppies and am now using it exclusively. I've used two for louder slab gigs with great success. They weigh about 20 pounds and are a couple inches larger around than the wizzy, but will go louder and sound much smoother. I can now run the Focus dead flat as well. Containing an Eminence Deltalite 2512, they are based on Fdeck's design which is tuned to 80hz with a rapid drop below that. However, they seem to have more low end than the wizzy. For anyone with some power tools and $150 this is a very nice little cabinet. I will miss the schlep factor of the wizzy, and my box doesn't look quite as nice, but the sound is worth the tradeoff.
