    Just WoW!

    Posted by Daytona Jeeper on Apr 08, 2024

    Exceeded expectations across the board. Just one of these with 120 watts sounded cleaner and way louder than the other three infinity kappas that were in the car as I was upgrading. This one speaker literally out sung three. SQ was incredible and the aesthetics are just awesome. What really sold me was the range the things have. I have 4 if these running in a jp95 on only 2 channels @ 2 ohm backed by a set of kicker comp r's @ 1 ohm, and a set of polk 1" silk domes @ 4 ohm on the remaining two channels all in a scion tc . Music is now an experience for daughter and anyone within 300 feet of her. Don't bother rolling your windows up, you will only provoke her. I am ordering 8 of these for my boat and can't wait to put them in.

    The lows

    Posted by James on Sep 28, 2023

    Best pro audios out there. What makes these different is that they will play down lower than any other pro audio out there but will also scream like you expect from a pro audio speaker. They dip down in the midbass rang but play just like a mud range speaker. Very versatile. Love these speakers.

    The lows

    Posted by James on Sep 28, 2023

    These are the best pri audio speakers on the market. They can still scream like you expect from pro audios but these will hit lows that no other pro audio speakers can. Great from someone that is needing alittle more range. They will dip down in the midbass speaker range but will still play like a mid range speaker. I love them.
