Prototype motor paired with new 12" frame, 9.25" spider (what we use on Z v.3 18s now), and the new cone / surround. I literally JUST finished it so I cannot play it until tomorrow. That being said... it won't QUITE be able to use ALL of the clearance we have -- and that is great -- should be INCREDIBLY rugged and hard to damage
For those not current on all of these parts -- they are ALL prototype parts. They are not in production yet. Production parts will start appearing 1Q 2013.
