Music Comes to Life with MTX Audio RTL Series Subwoofers

Out with the old and in with the new. This is the motto for MTX Audio's new Road Thunder RTLS series subwoofers, like the RTL12-44. The new Road Thunder RTL series subwoofers all have a power handling rating of 400 watts peak and 200 watts RMS, making them the perfect entry-level subwoofer. These new woofers feature a polypropylene cone for durability and longer extension from high excursion, while the stitched rubber surround reinforces the woofer cone, so you can play louder and longer. In order to keep the subwoofer at safe temperature levels, the RTL subwoofer incorporate a Spider Plateau Venting that cools the voice coil directly for increased performance and power handling. The use of an Asymmetrical Linear Driver System (ALDS) allows the RTL subwoofers to have high output with minimal distortion by creating a constant linear movement that creates optimum sound waves and thus increases performance for the highest music reproduction possible. MTX Audio's new RTL series subwoofers will provide the right amount of bass at the right price with features not found in other subwoofers in the same class.

great subs

I own 4 of these bad boys and man they hit hard!!! I installed them on my 2002 grand marquis wired to a MB Quart ONX1.1000D and my rear view mirror keeps falling off, ha!! 9.3 cf ported box.

They R aight

I have these in my 2011 reg cab ram in a dual box with 1.25 c/ft each. I have a RE 1000.1 amp so they're wired at 4 ohms at about 150 watts each so I know they aren't getting what they can but they still sound pretty darn good. Not very loud and im sure you are not gonna be waking neighbors even with the recommended watts but I can tell you I had kicker comps, kenwoods and pioneers and they sound better than all of them combined. Very unique and very tight bass. So buy it if you care about quality not loudness and if you're on a budget on both money and space =) OH one of them started making a noise so I had to replace it but the box was in bad shape so I blame it on ups.
