Hello All:

Want to know best way to seal a driver's frame to the cabinet.(lipped recess for flush mount) Parts Express gasket material, silicone caulk, perhaps mortite? Also cabinet has removable back panel, appreciate best method for this situation as well. I have an old Wharfdale W-70 cab which used gray felt around back panel frame. Is this still a good option?(felt source?)
All opinions welcome. Thank you.

Mark

  I've used all of these and have gone back to traditional foam gasket or tape as you would buy on a roll from a Home Depot or Lowe's. It it available in enough widths and thicknesses that you can surely find one suitable for your particular driver. When you use a sealent that is more like an adhesive you'll often find that when you want to remove the driver you'll take a bit of whatever is behind the sealent along with the driver. Especially true if the cabinet is MDF or some sort of particleboard, fiberboard. These other options are just a mess to work with, too. YMMV.

  I like Mortite, because it seals well, but remains soft in case you ever need to remove the driver again. The silicone bond is too hard to break, especially with a recessed driver.
  
  The old felt gasket on your Wharfedale cabinet has probably compressed/hardened a bit over the years. Replace it with comparable felt weather stripping from local hardware store.

    Silicone outgassing as it cures can cause the adhesives holding the surround to the cone or frame to fail (been there, done that, got the shirt).

      Good thing most of us have the sense to not glue our drivers in place :)
      
      
      
      
      
      Bass is supposed to sound big. 6.5" is not a woofer size.
