Mach 5

I know what you mean. I was trying to find their website the other day to get the t/s of a spl15 that i have. This is what i found, but all the pages where under construction. iST Ltd.

Edit- Looks like a few of the pages are working now. Too bad you want a 12, that 18 sounds pretty impressive.

 
Yeah, for some reason they've kinda disappeared over the last year...at least in the forums I frequent. I'm sure Mark is still working on stuff, I just think he needs to keep us internet people updated since these forums are the main lines of communication between the "underground" companies and their customers.

 
They just re-did the website. Mach 5 is still up and going.

This is off the front page too, sounds very fun.

" 21 Inch Subwoofer Coming

Sufficient interest has been garnered for IST to

invest in parts to make a 21 inch subwoofer. The

new unit will utilize the same motor, low distortion

voice coil and shorting ring as the upcoming 18 inch

high excursion sub.

Also on the horizon for serious car audio enthusiasts

is a 18 inch monster which simply won't take no for

an answer. We are talking a motor in excess of

100 pounds, 4.5 inch voice coil and a special layered

carbon fiber cone - not for the faint of heart!"
