    I was wondering if stuffing a JBL PB-10 will help in the boomy bass in my room. Due to the design of my apartment, the only place I can put this is in fromt of a wall (max distance) of 10". I was wondering if I stuff the sub, it will reduce and tighten the bass.

    Questions or comments please post here

    Thank you

    If you stuff the sub it shoud certainly tighten the bass. It's a cheap experiment anyways and the outcome can be well worth it, especially if you're looking to tighten the sound.

    OK if so, how much do I pad/stuff it. Tightly packed or loosly?

    Mark,

    This is a ported sub, correct? One thing you want to make sure of is to not to block off the area between the driver and the port. Start out with lining the walls and add or remove stuffing "to taste". When you like the sound or don't notice any more improvement stop.

    Also, what are the dimensions of the enclosure?

    Mark,

    Assuming the enclosure is made of 3/4" material that would give you roughly a 12.5x12.5x14.5 enclosure internally. This is equivalent to a 1.3ft^3 before taking into accout for the driver displacement and any bracing (which is doubtful).

    I'd start out with around 1/2 lb. of fiberfil and see how it sounds. If possible, glue or staple it to the side walls to keep it from interfering with the driver and port.
