Hi everyone,
I am building speakers cabinets and have heard that some glues/fillers are not safe and they may damage the drivers.
To glue the cabinets together I plan to use standard wood glue. I assume that this is safe.
But, what can I use to:
1) glue the polyester sound absorption sheets to the inside? I have some Wilsonart 600 Contact Adhesive used for wood cabinetry. Is this safe?
The trick with glue is to allow the solvents to cure fully so that they will not attack any other materials in or around the enclosure. 3M makes any number of spray adhesives that will allow you to mount those sheets on irregular surfaces. They are "art safe", and so pretty benign when cured. Allow them to cure for 48 hours before sealing anything.
2) what about filling the inside joints to stop air leaks?
There are any number of electronics-rated silicon sealants (no acetic acid), there are neoprene-based rope-caulks, and butyl-based sealing tapes that remain soft pretty much forever, and there is always non-acidic hot-melt glue.
Do not use standard RTV silicon sealants or caulk - the acetic acid will attack anything brass, copper or bronze based.
If you are laminating the exterior (veneer), make sure that you use either a paper laminate or some other sealing material on the inside as well. This prevents cupping and swelling of the substrate, especially if it is MDF.
Try to find cabinet-grade substrate, after all, the cost of the 'wood' is a mere fraction of the cost of the drivers and your time in putting it all together.
