Before I get rolling on the stuffing stuff, some (maybe?) good news. Those 6.5" dustcaps I picked up from PSI (fixmyspeaker.com) earlier? Well they look great but at ~$8.50 per (plus shipping) it can add up with many woofers (6 of them was $54.75 shipped). While I think the JBL is still a good value, it's less of a good value paying that. Robot Underground is near me (they're in Mesa AZ) and going out of business, I happened by and he has the exact same dustcaps. I picked up a bunch of them at a good discount for my projects figuring I could either use them all or turn a few over to any of you guys who might be interested if any of you are turned off by the ugliness of the stock cap. If enough of you want them I'll just swing by again this coming week and grab more of them for you.
I guess post here or PM me and we'll work it out? If you're at all interested it's as good of a deal as I think you're going to find for $4 plus whatever shipping is. They're polypropylene, plain black, 6.5". Patrick recommended a slight scuff to both the glue area on the cone as well as the bonding area of the dustcap before gluing and leaving overnight.
100% guaranteed to have been inspected by Walter, who assures me he is an expert in all things inspectable.
Edit: Priority mail is about $8.00 to ship. Also, the dustcaps weigh ~29g. 10 of them were 286g on my scale, I wouldn't bet the farm on the scale accuracy but it's going to be close to that for anyone that wants to model the impact of increasing mms. No clue what the stock JBL cap weighs, I wasn't planning on removing them, I like a little extra mms for my purposes.
