    I tried to look through the past threads about this specific project, but couldn't find much. Has anyone modeled the 1803 in a small (relatively) sealed enclosure? I have an 1803 on order, and a Mackie 1400 planned for driving it. Obviously I would need something like a BFD. My modeling program (Bass Box Pro) isn't helping very much. Thanks for any input.

    Jim,

    You could get by with around 4-5ft^3 and use the BFD to boost the low end as well as eq out any humps in the response. This is probably what I will do instead of the LT circuit. Just using the BFD allows you to tailor the response specifically to your room. You can do the same thing with the LT circuit but would be much more time consuming. You'd have to build the circuit, measure the response, then alter the circuit if you wanted to change the response.

    If you download the LT spreadsheet and input the numbers for the 1803, you can get an idea of what it takes to achieve a given SPL at a given frequency, and how this requirement goes up as the box size goes down.
