Excellent SQ in 1 cf sealed box - using 125 watts- Good tight bass

  • Summary: I am old school. I competed back in the late 80's with Lanzar, Orion, MB Quart, and Autotek but am going back to college and had a friendly school comp. coming up. I bought this and a 1 cf sealed box. These are not as efficient as the old Lanzars. (86 vs 94db ) but the bass is tight and quick. I hit 120db in a 4 door car with the 1 sub in the truck and a rated 44 watts ( 2 x22 ) amp running mono. Actual output is 120-135 watts at 2 ohms. The bass is great.

  • Summary: i have just one in a bassworks ported box i was worried it wouldn't be enough but i was wrong, sounds great and more then enough bass with out being over powering that you cant hear any of your other speakers, still shakes the mirrors no problem, dynamat in the trunk is a must stops the rattle and sounds even better , great buy for the price just make sure you get the proper box for its specs and proper amp to power it, and enjoy
