just for information.....i've had this driver from new....it is an all purpose speaker and was loaded in ev 606 design box and always sounded good....(not too much bottom end,but
punchy).....i surpose in sound it had elements of a 12......cab was mdf and too heavy....will probably go for compact bag end design....easy build(got all hardware)
with reference to the size of voice-coil....i believe it is 2.5 inches.
never heard speaker farting on bottom end....and its had some punishment over the years!!
well there you are me dears.....i'm off to buy some 5mm plywood ,grill cloth and some six inch nails!
