Hello all!
I am building three JBL B460 Subwoofers. Now I've come to insulating them. I use fiberglass wool (the yellow glass wool) It is 30 mm. thick, about one and 1/4 Inch thick. From the pictures I've found online I have not been able to determine if the insulation shall be everywhere inside of them. In the JBL Professional Enclosure guide I read that five or six of the interior sides should be insulated. But I have seen pictures online with insulation in the bottom.
Should the insulation be in the ceiling, bottom and on all sides?
Also, should I attach the insulation with staples even though the staples may make a "dent" or make the insulation more compressed at the place where it is attached with a staple?
I am on the lookout for long staples and such a staple gun but considers some glue perhaps but it does not feel right if the owner wants to change the insulation in the future.
(The bottom in one of them is 20 mm. or about 3/4 of an Inch higher and one of them is turned as per customer request)
Thank you all for the forum and all knowledge you contribute!
Kind Regards Johan in Sweden
