GAS ALPHA 6K is a 6.5” kit system with high quality. Wonderful mids, with good pressure and speed, complemented by a surprisingly good treble for this price category. The kit system is easy to use and works well even with the built-in effect of the stereo. The treble with a dispersing lens provides a more detailed reproduction at higher frequencies. Powerful magnets provide good pressure at high loads without producing bad sound. The GAS ALPHA is and remains one of the most affordable speakers on the market.
