Howdy all.
The back panel on one of my Klipsch KG 4.5s is somewhat loose and rattles/buzzes during loud, bass-heavy sounds. The color of this speaker's sound is somewhat darker than its twin also, I presume also caused by the loose panel.
I can't really remove the panel to do a proper gluing job, so my only option is to either screw it to the cabinet and/or put some glue in the tiny gap between the panel and the side of the speaker cabinet.
I think it probably makes sense to do both screws and glue, but I'm not sure. I also don't know what glue to use for this purpose.
What do you suggest? Thanks for the help!

Are you able to get sufficiently inside the cabinet with the drivers and crossover removed? While the quick and nasty solution would be to use yellow cabinetmakers glue and screw from the outside, what you're hearing could be from something else going on inside the box - such as a loose cleat / bracing strut, or even loosened joint on mitre jointed side/top panels.
I'm not familiar with this particular model, but recently built a new pair of vintage Heresy's in plywood for a customer. The originals were from his dad's system - they had seen some rough trade and were beyond easy salvage. In disassembling them to use the front baffle as pattern for new hand routed panels, I can't remember seeing anything more than standard V-Groove folded mitre joints on 4 perimeter panels, and fronts and backs were dadoed with minimal glue block battens. This type of construction has been standard in the industry for many decades, and is more than sufficient, unless the cabinets are subject to mishandling / dropping, etc - then all bets are off as to maintaining their structural integrity.

Loctite PL premium, a polyurethane glue, it expands slightly forcing itself into the crack, dries hard but doesn't become brittle, even retains some flexibility.
I use local equivalent here for pretty much any sort of gluing, wood, metal, plastic (other than the non sticky ones), especially loves porous moist surfaces, it is seriously amazing.
