XMAX?

Efficiency is a useless spec for determining output in a box in a vehicle. It is very possible that the low efficiency JL would womp yours in SPL with 50 watts of power.
As for anyone actually answering his question Xmax is just a measurement of how far a sub will move. I would say 12-13 mm is about average nowadays, 7-9 mm is what most budget subs do. High end subs can be up to 30 mm nowadays.

True dat, Xmax is just a spec that CAN give an indication of performance, but does nothing to tell you how something sounds. Some of the worst spec drivers sound incredible. Just check out a CA&E mag and they rag all over drivers for bad specs (like suspensions glued up off center) then Eric Holdaway raves about it's sound.

well the reason i asked is because the subs i have seem to be in the low class as far as Xmax is concerned. on my subs they are only a 7mm. i dont consider it to be a budget sub even for a pioneer. especially being a premier series and the rms rating is like 400. plus the are fairly pricey. i hope it can perform to the expectations as what i paid for it. actually im hoping xmax has little to do with its performance since of its low rating. any thought?
