I just ordered one of the last Atlas 15's for Ascendent Audio. If you have been tettering, call now! I ordered the two 4" precision ports as well to do the 24" cube vented design. I am going to build this into an equipment rack, with the sub disguised as a lower cabinet with a false door. Should turn out ok. I am excited to say the least. I am also building GR Research AV1's for my temp fronts. They will be relegated to rears when I do the AV3's. Wish me luck!
