The RTS15-04 is one of MTX Audio's new 2011 Road Thunder RTS series subwoofers. The woofer has a power handling of 600 watts peak and 300 watts RMS and has been specifically design to withstand extreme amounts of power without failure or damage to the woofer. The woofer features a polypropylene woofer cone and high-roll rubber surround for increase durability, strength, performance, and greater volume displacement. For increased power handling an 8-layer 2" aluminum coil is used which enables the woofer to perform consistently at higher volume levels. The use of Spider Plateau Venting cools the voice coil directly for increased performance and power handling. The RTS subwoofer also features an Asymmetrical Linear Driver System (ALDS) that allows higher output with less distortion by creating constant linear movement that increases performance and sound quality. This RTS subwoofer was designed to be perfectly paired with an RTS amplifier and will deliver quality, rich and responsive bass that is often not seen by other woofers of its class.

Boom for your Buck
I Purchased 3x on sale $80- each & got a free sealed Belva box with each..... (Using 2 kept 1 for "back up") Over the 15-20 years I have had many subwoofers probably 200+ (JL W0 to W7, Solobaric, Kappa, IDQ, TC, Hex, etc.) so I must admit I didn't have real high expectations, with that said I was very surprised & would Highly recommended these for those on a budget. After Broken in for 48-60hrs and added a little bracing to the Belva boxes I Gave them a test run. Short Version They are a well balanced 15 with decent efficiency and great accuracy even below 35hz. Considering the drivers price point it's a solid a performer & it would be hard to find a better deal that can TRULY reproduce these lower frequencies.
