These speakers have a unique and convenient mounting system. Simply screw on the nut from behind to fasten it to the mounting surface. No hardware required! The 360 degree rubber gasket seals it so water won't leak behind.
This is an exact replacement for speakers that come installed in many new hot tubs. They also work great in marine applications and for ATVs, UTVs, and motorcycles. These are tiny speakers that can fit in tight places where other speakers can't. Great when used in conjunction with a subwoofer for excellent full range sound.

They are very good products but should not be over evaluated. Considering their size and power, they are very good quality speakers. Especially the installation method is very good for everywhere.
I installed them to my motorcycle, and I rode under heavy rain on the way to Vegas. They are still working fine.
