TR Terminator Coaxial Speakers Ø10cm 4" 2-way 45W RMS 310W Peak 4Ω with Ø25mm Aluminum Voice Coil and Ø13mm Mylar Tweeter


The MTX TR40C coaxial speakers shine with their sound quality, very high power handling and exceptional finish. It is advisable to use the TR40C with a small amplified subwoofer such as the MTX TRT8p, RTT8P, TRP8, RTP8 or RTF10P to reinforce the low frequencies.
The quality of a loudspeaker depends 2/3 on the quality of the assembly. It is necessary to perfectly seal and stiffen the support with the speaker and the door.
To enjoy all the sound quality, it is strongly recommended to use an external amplifier such as the TR275, TX2275 or the TR450, TX2450 whose power and musicality transfigure the music.
