Just a heads up. There's a new woofer coming on the market from Mach5audio called the IXL-18.4. The specs are:
Fs = 15.4Hz
Re = 3.2Ohm
Qms = 4.87
Qes = 0.39
Qts = 0.36
Vas = 556L
Sd = 1029.2cm
BL = 15.1
Mms = 228g
Cms = 0.37mm
SPL = 89.2
Xmax = 22mm
Pricing has yet to be set, but I'm willing to bet it'll be affordable considering the other Mach 5 drivers. Personally, I can't wait to build a couple of HT subs with these!!! You can read about it here.

Hi,
This woofer looks also promising for a sono-tube application.
As I don’t like the normal vented variant with the driver at one end and port at the opposite, I tested a TL variant I don’t remember the design origin of.
The tube was 225 cm and seems to work well for this new driver but - 10" less = 2 m even better and more optimal.
Driver sag is within rec. limits and for Usd 175 it looks like a bargain.

The new subs have arrived. The production T/S parameters have changed from the prototype. The VAS is now half of what it used to be. The new T/S parameters are:
Fs = 17.7 Hz
Re = 3.4 Ohms
Qt = 0.37
Qes = 0.39
Qms = 5.59
Mms = 434.3 grams
Cms = 0.184 mm/N
Vas = 274 liters
Sd= 1029.2 cm2
Xmax = 22 mm
Diameter = 36.2 cm
Notice the FS and sensitivity are also slightly up. Here's a few pics of the subs.

At under 200 U.S. for these subs, it has to be one of the best values out there. I'll be building 12 cubic feet tuned to 16 hz for these subs. Can't wait to see what they put out in my home theater!!
