The same principle that makes our 7.7 in marine speakers dominate over conventional 6-1/2 in designs is delivered in a more powerful dose in our M6-880X 8.8 in coaxials, with the added visual impact of our patent-pending, Transflective™ RGB LED lighting. These 8.8 in dia monsters offer significant performance advantages over our 7.7 in models and a huge advantage over conventional 6-1/2 in marine coaxials. Thanks to 36% more cone area and almost double the excursion capability, the M6-880X are capable of plus 6 dB greater low frequency output than our M6-770X 7.7 in coaxial systems. The bass is so impressive that the M6-880X can be used without a subwoofer while still packing a very serious low frequency punch. Used with a subwoofer, they offer vastly better dynamics and mid-bass impact than smaller speakers, making them the best choice when ultimate performance is desired. To make sure that the high-frequencies sound just as good as the bass, our engineers have designed an oversized, 1-1/4 in, silk dome tweeter for this model. This new tweeter plays louder, cleaner and extends lower in frequency to better mate with the 8.8 in woofer. A high quality, true 2-way crossover network precisely filters and balances the coaxial system for outstanding fidelity. Although M6-880X coaxial systems can be used with as little as 50 W per channel, but for best audio performance we recommend amplifiers capable of between 50 – 250 W of continuous power per channel. The patent-pending Transflective™ RGB LED technology emits a smooth lighting effect through the woofer cone, with a choice of several lighting colors. Add an optional RGB controller to create thousands of color variations. Professional installation is strongly recommended.
