I am building 4 single 18" cabinets, 8 ft3 internal with a 23.7hz tune.
They will be loaded with 1ea FaitalPRO 18HP1060 neodymium subwoofers.http://www.faitalpro.com/products/schede/hps.php?id=201070125
Each driver is 4ohm, and pairs will be running parallel creating a 2ohm stereo load on an Ashly KLR-3200 delivering 1600w per pair and 800w per driver. As such, all simulations are done at 800w.

Fun build stuff!!
Getting the wood, I <3 my Blazer. 11 sheets .5 and one sheet of .75 Birch, some scrap .75 ply from the tapered pipe experiment for bracing:
Birch cut up:
Everything rough cut:
Glue and clamp the finish cut portions:
Bracing installed, and driver holes cut, with a very dusty Wi:
From head to toe:
I'll be finishing them up with shop time tomorrow. A pair of drivers is coming tomorrow, another pair on Thursday. All the speakons, dishes, and feet will be arriving Thursday as well. I hope to measure the cabinets Friday weather depending. There will be more pics tomorrow evening, I hope to have all 4 running by Thursday night. Friday is the big Gridlok show, I'm not completely sure what configuration I'll be using yet. All depends on what these do.
I was originally going to build these around the Ciare 18.00SW, but this happened:
With a perfectly clean coil:
Needless to say, I don't like a 14mm Xmax claim with no stated Xmech. The rubber surround looks cool, but you clank it WAY too easily.
I have had my eye on the Faital product for a while, and have one of the mid line drivers in the tapered pipe outdoors and it humps. We'll shortly see what the HP line has to offer. If they don't work out, I'll probably just put Zv3 18s in there or do a LF/ULF split.
