The MTX TX465S speakers shine with their exceptional construction, sound quality, efficiency, including the size of their magnet. They do an incredible job in the original locations of most vehicles. The softness and force with which they reproduce the best recordings is exceptional. The semi-pressed paper membrane covered with crystals and silver is musical and clear. The oversized magnetic structure ensures an astounding dynamic and power handling. The 25mm soft dome tweeter in silk and neodymium magnet is a delight. This last characteristic is rare at this price point. It is more often found on models twice as expensive. They work perfectly on a factory or after market car audio system, but they are sublime if connected to an external amplifier like the MTX TX2450, Thunder75.4 or TX480D.
