    with a surround that big, how much effective cone area are you loosing out on? i kno the extra Xmax probobly makes up for it, but for some reason it looks like the surround is too big. lol

    On the 10" model there is equal and/or slightly greater SD than most 10s depending on the calculation method as the 10" frame is slightly over-sized.

    On the other sizes there is a ~10% difference.

    gotcha. thats what i thought after looking at the Sd spec. too bad you cant do a surround like the W7. ive always loved that look, and you gain piston area with that method. doesnt JL have that patented tho?

    Matt

    edit: also whats the Xmax on these suckers?

    JL does have a patent on their surround method; it is cool but I've always thought it opens up too much possibility of end-user error. Knowledgeable folks would have no problem at all but I'd worry about beginners.

    Linear x-max by 70% BL is in the high 20s (I will be getting Klippel done on a Z v.4 to verify FEA predictions) -- we can get the coil to 47.5mm in the physical gap -- and I've moved it up to ~60mm into the fringe field (not a good idea). We are using alot of the excess suspension capacity as a safety zone in the current driver / coil setups being displayed -- I will have a "super excursion" coil option available for the Z v.4 and NS v.3 that will get you into the mid to high 30s linear but does eat away at the safety net and, naturally, has a higher MMS and inductance. This coil would be capable of 55mm in the physical gap and would also bottom out at 55mm (longer coil leaves less room in the motor).
