MTX RFL5300 picture


Flagship class-AB 800W RMS 5-channel Hi-Fi amplifier with ultra-complete variable active x-over


The MTX RFL5300 5-channel amplifier is a daydream. With only one amp, and all that implies in terms of size and ease of assembly, it is possible to make a very high-end installation complete with state-of-the-art filtering. The build quality and the quality of the components used make this an exceptional amp. It's a slightly deflated RFL4120 but with a class-AB sub channel that hits. Hi-fi Sanken transistors, three separate power supplies, racing capacitors, we spent lavishly...


  • Exceptional sound quality thanks to class-AB topology.
  • High quality components (Sanken hi-fi grade transistors).
  • All aluminum construction with backlit window to admire the components.
  • Triple power supply converter (One per amp) to better manage current and power.
  • A whole installation in a single amplifier: simplicity and efficiency (3 amps + an active filter).
  • Flexibility of the active filter capable of doing everything (3 active channels or front-rear-sub).
  • EBC remote level control included.
  • Ø50mm² power terminal block


  • 5-channel Class-AB amplifier
  • CEA2006 certified power:
    • 4 channels: 4x120W RMS @ 2Ω THD + N ≤1%
    • 4 channels: 4x80W RMS @ 4Ω THD + N ≤1%
    • 4 channels: 2x240W RMS @ 4Ω THD + N ≤1%
    • Mono channel: 1x370W RMS @ 2Ω THD + N ≤1%
    • Mono channel: 1x250W RMS @ 4Ω THD + N ≤1%
  • Active filter channels 1 and 2:
    • High Pass (HPF) 12dB / oct variable from 40Hz to 5KHz

Recommended performance associations

TX6 TX8 Speakers - TX612 TX615 Subwoofers


Recommended effective combinations:

  • In five active channels (tweeters + midrange + sub) with TX8, TX6 speakers and TX612 TX615 subwoofer
  • In five active channels (2-way + bass + sub kit)
  • Recommended power pack: MTX StreetWires ZNX50K


The power of the amplifier must not exceed that of the loudspeaker. We must compare RMS powers with RMS powers. The amplifiers should not be exposed to moisture, excessive vibration, or high temperatures.
