    Would it be acceptable to use a spray bedliner material to damp the inside of an sonosub, instead of the traditional batting. Is it absolutely neccesary to damp the inside of the tube or is this critical only with the taller versions.
    Thanks,
    Jason Pannell

    The bedliner material won't be of any significant benefit for a tube sub.
    Adding dacron batting or fibreglass batts will abosorb the higher frequencies that aren't filtered by the crossover, and they can be helpful with potential standing waves.
    My experience is that all subs benefit from the addition of damping materials.

    I sprayed some bedliner in mine and wish I hadn't. It was goey with an asphalt smell that took a long time to dry. Since the unit is sealed, i worry about trapped fumes from the bedliner harming the rubber portions of the driver.
