i'd still like to know what GLITCH made the site keep deleting EVERYTHING after the 92dB rating in specs, even the last time it happened when i "successfully" re-added the rest of the specs and never touched the edit button after that.i just do a lot of edits. things occur to me after the fact that i need to add.

i'm still waiting for feedback on the actual topic of this thread
1. will the VB woofer be significantly better sounding DESPITE the 3dB resonant peak and 1.35Q? (which i should be able to compensate for to some degree with my amp's continuously variable crossover, and an EQ down the road if need be.) i've tried to look the topic of "what Q is too high?" online to no avail. i've ALSO tried to find 2.5 cubic foot boxes to no avail other than super heavy internally MDF lenovo knockdowns with flush mount routing for dayton woofers that's 3/8" too big for the VB
2. if upgrading to the VB is the better choice, then which wiring option is best?

Ok.
bear in mind, the MCM was originally intended to be just a temporary sub while i saved up for a pair of 2 x 12 boxes, but now, i've stumbled across really cool "LED sunflower" effects, like this:
https://www.youtube.com/watch?v=ao_Cj7wivdQ
and have decided, that if they look half way decent in real life, i will keep the JBL to save space and build a white nylon shell around the system and put one sunflower inside each side and top panel with shields along all of the edges to block light spillage and turn the whole thing into a mobile light show.
sunflowers are smaller, lighter, and cheaper than disco projectors which would require building wonky looking towers to get them high enough to project a decent sized pattern whereas, with sunflowers, i can turn the nylon into a seamless extra bright light show. i like simplicity. an illuminated monolithic slab is much more my style.
with everything hidden, i'll drop the sub a few inches and point it down for both a lower center of gravity and to couple with the pavement. until then though, i'll put it on display.
i doubt i'll find another sub that hits as hard as the JBL without spending more money.
