Very Fast

I ordered these speakers by telephone, as my computer was down. Sonic only had one set in stock at the closest warehouse, so they had to send them from the southern states to upstate New York. They expedited shipping at no extra charge and were at my place in about a week. I was impressed, as this was just before Christmas.

Great Sound!!

After a short break-in period these speakers sound great. Drums sound like they are in the car with me. I matched these with primus components and have terrific full range sound. I recommend them to anyone looking for great midrange, a surprising low end, and crisp but not shrill highs. I love them! A steal in my opinion.

Wasn't very pleased

I bought the speakers maybe 3 weeks ago and the right speaker has already gone out on me. With these being infinity speakers, I figured they would last some time with me rather than just 3 weeks.

Incredible!

Bought these as a set to upgrade my entire Jeep speaker set...for under $200! They were installed in the rollbar and really boosted the mids and the highs rain down like a summer rain. Totally worth the money.
