The MTX TX650S (4" 2-way separate 4Ω 80W RMS 555W Peak) are high-end coaxial speakers. They can handle a huge power and you can't imagine the sound quality they can produce. They are equipped with all the best: MTX aluminum chassis for optimal rigidity, aluminum phasing warhead to neutralize standing waves, pressed paper membrane for more musicality, detail and warmth, magnet giant for incredible power handling, extra-large 30mm diameter TSV TIL coil for detail at all levels and power handling thanks to better cooling, neodymium magnet tweeter and 22mm silk dome diameter for a soft and dynamic sound, rubber suspension to withstand large deflections while remaining reliable.
The TX650C shines with exceptional construction. Its sound quality is breathtaking (It is at the level of TX8). Its price remained at the TX6 level.

Recommended efficient associations

RFL4120 RFL5300 TX480D TX2275 TX2450 amplifiers


  • Best results with RFL4120 or RFL5300 class-AB amplifiers (those using Sanken grade Hifi transistors).
  • Best used at the front. For the rear, the TX669C will be perfect.
  • Very good results with the passive x-over. The tweeter 6dB/Oct soft slope opens up the stagin and make an easy connexion with the woofer.
  • Its clarity and power handling allow it to be combined with one or two 30cm 12" or 38cm 15" subwoofers.


MTX wants you to enjoy your hearing for a long time. Excessive exposure to loud volumes can damage your hearing. The United States Department of Labor recommends not exceeding the following recommendations:

  • 90dB: maximum 8 hours / day
  • 92dB: maximum 6 hours / day
  • 95dB: maximum 4 hours / day
  • 97dB: maximum 3 hours / day
  • 100dB: maximum 2 hours / day
  • 102dB: maximum 90 minutes / day
  • 105dB: maximum 60 minutes / day
  • 110dB: maximum 30 minutes / day
  • 115dB: maximum less than 15 minutes / day
  • 120dB: immediate danger, 0 minutes / day





It is essential to use the passive x-overs to obtain the best sound quality and to protect the speakers. Be careful, without a x-over, the tweeters burn.
