Triple 20cm 3x8" Vented Powered Enclosure with 360W RMS Class-D amplifier and EBC remote control


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

Recommended efficient associations

The RTP8x3 powered enclosure is the perfect bass complement in an original installation with 4 speakers connected to the head-unit.
Same story if you replace the original speakers with better quality ones like MTX TX2, TX4, TX6. The RTP8x3 will give a new dimension to your sound system, and add what any speaker is not able to provide: deep and loud bass…
