Yeah, I bought that Crown just for the 250ti, but I use it on everything in the basement. It doesn't care what I ask it to drive—or how many!!
Aleene's makes a full line of glues, most of which are available at any Michael's store, or other craft stores. Not much more than a couple of bucks. I had to order one which is a heat-activated fabric glue I'm going to try on grille cloth that's worked loose on the L112 and 240 before it gets worse. I just need my wife to find her old iron that she'll allow me to use.
No, that mid-bass driver didn't need to come out, I just figured it was easy to do and any weight I could take off would make it that much easier to move them. Glad I did now that I know how badly they F'd up the T-nuts! All fine now.
