The Sigma Pro 18 seems to suck in this box. I'd recommend the 40Hz tuning with a steep high pass. It's just not going to be able to do much low end.

The graphs tell the story here. The Delta Pro 18As offer the best response in the box tuned at 50Hz. With the 50Hz tuning, the box will be about 10dB down at 40Hz, which is usual for many subs.

The Sigma will win in outright output from a power standpoint, but the Delta will win from the sound quality standpoint. Neither goes really that low.

I'm plotting the Definimax now...
