Active reflex box with triple 20cm subwoofers, 360W RMS Class-D amplifier, active filter and remote control

The MTX RTP8x3 20cm triple amplified reflex subwoofer (Class-D 360W RMS) continues the legend of the triplets dating back to the 90s. This configuration is fast and very powerful. It allows for "live & loud" listening without the risk of overheating. The highly efficient integrated Class-D amplifier delivers very high power, perfectly suited to the needs of the three subwoofers. The very rigid 15mm MDF cabinet and the high-performance RT8 subwoofers allow you to listen for a very long time at high volume, without the slightest distortion. The RTP8x3 is built like a big boy. It also has astonishing acoustic performance. The German magazine Car&Hifi voted it the best subwoofer and gave it the highest possible rating...

The RTP8x3 active subwoofer transforms your cabin into a battlefield. Its power and dynamics pin you to the windshield. It's loud, powerful, and physical... It's really good...
To cope, we recommend TX2 TX4 or TX6 speakers at the front with TX2275 TX2450 or TX480D amplifier.
