    Inside Boxes...

    HI, i heard somewhere, correct me if im wrong, that when you make a sb box with MDF, that by applying some minwax or some kinda sealer or something i dont know exactly, that it may help. it read that since the MDF is porous it smoothes and fills the pores. not sure if this is true or not. anyway, if you laugh, i didnt make this up, its hearsay! haha

    help what? what are you trying to accomplish? wax will do you no good in a sealed.... polyfill wont necesarily help you in a bandpass...

    Explain what it is that you're doing.

    Ahhh okay. You're prolly looking for Polyfill. It can help bring down the Q of a small sealed enclosure.

    Re: Inside Boxes...

    I think what they're trying to say is don't bother doing anything to the inside surfaces of an MDF sealed enclosure. Screw it, glue it, and run away. If she's pissed about the extra glue give her some soap.

    Re: Inside Boxes...

    I too have read somewhere that people use one of the products used in fiberglassing to coat all the walls. It was mainly just to ensure a perfect seal and no air getting through. But I just use good sealant/caulk to do the job. Seems to work just fine.

    Re: Inside Boxes...

    The February 2005 issue of CarAudio and Electronics addressed this issue when relating it to SPL. Spraying on something on the inside will not help SPL at an audible level, but in some cases might raise SPL a couple of tenths of a dB. But in your case, as long as you do a good job making the box, there should be no need to spray on anything, especially with MDF.
