The AX-408C line features a two-way system comprising four 8-inch woofers and four 1-inch tweeters. The woofers incorporate MMSS technology (Mirror-Image Mechanical Suspension System), which ensures consistent positive and negative excursion of the moving components, thereby achieving significantly lower harmonic distortion. The tweeters utilize PM4 diaphragm technology—a system employing advanced polymer materials never before used in the audio industry—to establish a stronger bond between the dome and the voice coil former. This design enhances the driver's performance during prolonged, high-power operation, delivering a more natural and authentic sound.
