What users around the web are saying:
From Amazon.com
"I was expecting a little more bass, not that they lack, but you get what you pay for when it comes to the bass. However, having 4 tweeters really opens up the music spectrum and releases all the instrumental you need. Paired with a nice set of 6.5" Component Speakers that more than make up for the bass, these things are awesome! GREAT COMBINATION! I have yet to wire these to an amp, so the bass may get better with an amplifier..."

"insane sound for the price...they sound amazing and the mids and highs are crazy clear. for bass you will need subs but these are great for everything else"
