REPLACING THE SPEAKER
Some people like to swap out the speaker in their cabinets from time to time, and for various reasons
– usually because they destroyed the original speaker, or they obtained a special or vintage speaker
and they are dying to try it out. We recommend you service your speaker from the rear, by removing
the top port and loosening the machine screws from the t-nuts in the baffle board.
You could loosen the baffle board from the front, but we recommend rear-service because we do not
want you to run the baffle screws in and out of the cleats more than necessary. It is important for this
connection to remain structurally sound, since these are the screws that hold in the vibrating baffle board.
If you must replace the speaker from the front, and you feel the wood screws are not holding well when
you replace the baffle, you can replace the screws with #8x1-1/4 or even #8x1-1/2 screws. If you
use longer screws, re-drill the pilot holes with a 3/32 bit, and go all the way through the cleats. If you
don’t like how a #8 screw looks when seated in the #8 countersink washers, you can use #10 washers.
