 Average Rating : 
Rating : - Best tight bass response for those not trying to show off with annoying noise Quality tight bass with endless capability for almost any realistic application. Sounds extremely clear, and when run at a normal volume sounds clean like a factory, yet will still provide all the thump you need. Used with alpine 400 watt amp, running about half on the amp and it is plenty.
