helo its me again.(I think may probably be the most stupid person around in this forum I dont know a damn abt this stuff ofcourse in comparison to all of u experts out there) (just incase ur curious I am 17 yrs old and i am lookiin forward to pioneer a subwoofer company in the future)

ok so my question is that wut exactly are the bass radiators and wut fuction do they do or wut do they enhance?
and can i use a sub woofer driver it self (which is not connected ofcourse) as a bass radiator in a sealed sub?
and also that what thick of mdf will be the best 4 a sealed sub?

and should i use any glue or silicon sealant on a papercone to make it rigid?

A bass radiator performs the same function as a vent and is used when the vent is too long to implement practically. Usually you need a radiator bigger in diameter than your actual drive unit and at least as much excursion. The weight of the radiator determines its resonant frequency. You can use an old speaker for it, just knock off the magnet to stop it producing any voltage.

The thickness of the box depends on how big it is and how much air is being displaced by the driver(s) and how good quality you want. Generally, you should be able to rap your knuckles on a box and it will sound dead and well damped/solid, not hollow.

If you've never designed a box before, I'd advise to stay away from passive radiators. the drivers you'll be using for your first few projects won't need passive radiators anyway.
