Blown DC XL 18

[tubatimmy]

Popped one of my Xl 18s last week and trying to see about a recone, not sure about the model of the sub itself. it looks fine but does not play and is very stiff, will not budge at all.  Does anyone know a way of telling which Model it is, Either M1, M2, or M4? and should i get the other reconed so they are the same? any help would be greatly appreciated

"The XLm4 has aN added pole vent," according to the website among some other additions. http//www.dcsoundlab.com/xl

Also found this here: 

 

Differences between the m1 and m2 XL.

m1- triple stiff spiders/ m2- quad stiff spiders

m1- 1500w rms/ m2- 2200w rms

m1- vented pole in motor/ m2- vented motor gap, machined air channels in pole and top plate.

Hopefully that answers your question better than "everything is different".
