Ohh.... and if your interested in bass. The nex SX-12, SX-15, SX-18 series of subwoofer drivers are going to deliver.
The SX-12 models well in a 3 ft^3 ported box (Rava size) and gives output similiar to the Sadhara. The two model really close so they are almost the same in terms of output and distortion. Power requirements are a humble 300W in the 3ft^3 to reach full potential. Our ADA-300 will provide ample power and a couple bands of parametric EQ to provide unmatched output/flexibility to tame room modes.
Home Theater Magazine reviewed the Sadhara along with a number of other bone crunchers.
"Sadhara provided the most output down deep, with 110 dB at 25 Hz at only 7.5% THD. In fact, reviewer Keith Yates noted that "Only when I compared it with the nearly $8,000 coffin-sized Genelec HTS6 subwoofer did the Sadhara seem to lack an authentically "ocean deep" quality".

http://www.hometheatermag.com/The SX-12 will retail around $300 so it should provide plenty of output for the dollar in a reasonable sized enclosure. We are looking at a couple low-priced amplifier solutions so that a DIYer could build this sub for less than $500 including amp, driver and enclosure.
SX-15 is the same XBL^2 motor with 26.5mm excursion. It works well in a 6 ft^3 box and provides substantial output down to the 15HZ range. In addition it will supply well over reference levels of output with vanishingly low distortion. It also works well in sealed alignments. Expect a retail price around $350 and it works well with the same 300W as the SX-12.
The SX-18 will be the real bone crusher with the same 26mm of excursion and works in 6 ft^3 sealed or 10 ft^3 ported. The Vd of this beast is higher than that of the Tumult 15" (@more than $100 less) Retail price should land around the $390 area.
Of course we will also have the Tumult 18" with 34mm of excursion. This is the REAL beast and it is pretty much without competition. Price should land in the $575 range.
