HUGE SOUND!

These little things punch out huge sound w/out distortion. They test my 5-chan amp to be honest. Go with these, you won't regret it.

Don't be discouraged by the size

These may be small but they pack a lot of power. I needed some small speakers for my jeep and with two of these they really made it loud. They provide really clear and crisp sound and the rotating tweeter for the extra boost is awesome and easy to access. I paid list price but Sonix really has a good deal here. Wish I would have seen it earlier. I would recommend this product to anyone. Infinity is all I buy.
