Prototypes arrived today... working on doing full break-in to measure official specs. Honestly I am super happy with the prototypes -- I do plan to tool a magnet boot and put our logo on the cap but I don't think any other changes are needed at all. SD-2 12" Measured Mounting Depth = 5.25" SD-2 10" Measured Mounting Depth = 4.75" ----- Early price estimates -- MAP price (actual price paid from dealer) (SA cost for comparison) SA-10 v.1 : $185 SA-12 v.1 : $195 SD-2 10 : $150 SD-2 12 : $160 Pre-ordering would be something like : SD-2 10 : $115 SD-2 12 : $125 That would be shipped in the continental 48 states. Once I do some testing we'll have an ETA and a time when pre-ordering will begin. ----- * Quite a bit less depth than the SA series for depth restricted applications.
