These speakers work extremely well when driven properly. Im running a 300 watt 2 channel amp, and they perform as well as speakers that are twice as expensive. They respond well down to 50 Hz. They dont fall on their face when you turn up the volume. The highs are clear without being irritating.

For the money...None

They sounded as good as the Kicker plates that are 3 times as expensive. If you want a clean full sound in a 5x7 door or rear panel, these are a super way to go for about 60 bucks.

Tried a couple of similarly priced plate combos i.e. Clarion, Planet Audio, the Lanzars blew em out of the water.
