This little driver was impressive. It did not distort at volumes I'd never listen at. It sounded clean and even airy at times. Great little driver for an inexpensive full range DIY project. It looks cool too!

Replaced a Polk blown speaker . Sounds so much better now I'm considering changing out the other with the other Dayton, the one with slightly less bass and a bit more treble for a good balance (center speaker for 5.0)
