I got these speakers from a friend after trade for an old MTX competition subwoofer because I needed new 4's for my dash. They are a little deeper in design so fitting in my dash was a challenge, but they have incredible clarity and sound good just off of RMS power. They are definitely worth the price if you need 4" speakers.

These speakers are incredibly accurate for mid-highs and highs. With a good set of mid ranges and a sub these speakers are the perfect add-on. The highs are very crisp, and the mids are very good too. Do not buy these speakers if you are looking for bass in the least. Don't buy ANY 4" speaker looking for bass.

Overall, a great speaker for highs in the front.

This current speaker i just purchased because my two front 4" speakers blew in my dash and i purchased these and they arent much of anything to spectacular. besides they play pretty clear but i guess you have to keep in my you cant recieve much out of a 4" speaker versus a 6 x 9 KAPPA series infinity speaker, those are nuts!

Customer Testimonial

I wanted to write and give thanks for Ricky's efforts. He looked up options while I was busy at work and gave good advice and was knowledgeable when I wasn't.
