Flockhart flat? Damn that must be flat! \:D Thanks for the suggestion on the 15. I have about 9cu ft. I can use. Now I just need to figure out how to use WINISD.

Just to follow up here.

It turns out that the shipping charges for the SDX15 were not as cheap as I thought. $80 just for the driver is a little steep for me. The amp would be another $50 or so.

Luckily, Kevin Haskins from DIYCable offered up $43 shipping for the Exodus Tempest X2 (15 incher) and I got an OAudio BASH 500 coming for just $19 shipped.

So, the plan now is to make a sealed 6^ft (net after stuffing) enclosure with a Q of .675 for the Tempest and let the low end boost features of the OAudio amp get me to a 32hz F3. I should be 7db's down at 20hz. Hopefully my room gain can make up for the dropoff and get me closer to flat through 20hz.

May just be my imagination,but I've always liked sealed subs better, but if this design doesn't work out, I have a ported design as backup.

Got all the mdf cut and am starting to put the box together. The driver should be in this week, and the backordered amp should be here in two weeks.

The Tempest-x2 is a nice driver too. You know, ported would get you down to 15Hz quite nicely. ;\)

Let us know how the build goes.

I have most of the box together, but am still waiting on the driver to drill out the mounting holes. I decided to glue strips of plywood on the back of the mdf so that the screws will have something to bite into. I just don't see t-nuts or hurricane nuts as a better alternative to a simple wood screw.

I've been told that the OAudio amp won't be available until mid January due to a parts shortage. I'm considering going with the Parts Express amp, which would give me greater flexibility with ported designs down the road, but I already cutout the mounting hole for the OAudio. Also, the box was designed for the OAudio as it is a little smaller than I would have liked if I went with a more conventional amp with minimal or no boost at the subsonic cutoff frequencies. With no guarantees for the January timeframe, I may have to find a creative way to patch up the hole and mount the PE amp on the other side.

If anyone has a suggestion for an 500W+ amp/single band eq combo for under $300, I'm open to suggestions.

Tapco Juice J800 + BFD 1124. Much better than a plate amp. 800w bridged into 4 ohms.
