The MTX TX665S (6.5" 2-way separate 4Ω 90W RMS 620W Peak) are high-end component 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, phenomenal neodymium magnet tweeter and 28mm silk dome in diameter for a soft and dynamic sound, external passive filter with esoteric components (ultra musical polypropylene capacitors, unsaturated air coils), rubber suspension to handle large deflections while remaining reliable.
The TX665S shines with exceptional construction. Its sound quality is breathtaking (It is at the level of TX8). Its price remained at the T6/TX6 level.
