Do the kits come with adequate instructions for setting the voice coil height?
-seems- like the bottom of the 2235 VC should drop in about 1.9mm lower than the 2225 (.6" vs .75" coil), but I'm no reconer!
I'd want it done right, and I have never built up a recone kit from scratch. Seems a path fraught with peril (or much learning) without the proper tools/jigs/experience.
Official JBL kits came with the spider and VC pre-attached.
