I'm with you on that; 8ft^3 is a seriously large cabinet. For $200 they look like amazing drivers though.

We're talking about 18" woofers here.... 8 cu ft for a vented sub is par for the course. If you want smaller, don't use a vent (20mm is pretty useful excursion for sealed). You can't get a 20hz tune without the internal air volume to meaningfully excite the port at the frequency!!
The 8 ft^3 enclosure was for the 15". We have two different surrounds coming in that have different chemical compositions which make them more compliant than the surrounds used on these prototypes. We also have two different compliance's of spiders coming in as well - both much softer than the spiders (single spider per woofer) listed here.

AKA: We are continuing to tailor these drivers to suit you guys the best way possible so that when production starts they will be very pleasing to you guys.

I still think it's on the large side, but I understand your point. I'm just hoping us acoustic suspension guys will be served by this driver too. Those spec's, at that price, make for a very enticing package.
As promised we got a better hold on the pricing that is going to be offered. We will be able to offer the 15" at $170 and the 18" at $190. Both prices are plus shipping. We will also do discounts on multiples of four or more.

Right at 4 ft^3 for the 15" and between 5-6 ft^3 for the 18".

How come I'm noticing two different style baskets on the prototype drivers ?

Because the twelve spoke 18" frame is owned by a private company and the six spoke 18" frame is open tooled and allows just as much clearance in all areas as the twelve spoke does.

Looking very promising. I've been wanting to build a pair of sealed 15s or 18s. Would love to give these a shot. I got tired of waiting for the SDX15IIs.

When are these going to be available??
