JL Audio M6-770X-S-GmTi 7.7" 250W Marine Coaxial Speakers-Gloss White Sports Grills (Pair)

JL Audio M6-770X-S-GmTi JL Audio 7.7-Inch M6 Marine Coaxial Speaker System, Gunmetal & Titanium, Sport Grille - SKU: M6-770X-S-GmTi M6 Loudspeakers fulfill JL Audio’s commitment to raise the bar with each product generation. The JL Audio engineering team has completely reinvented the premium marine loudspeaker, with major improvements in performance, precision and durability. Offered in multiple sizes and cosmetic options, most models are also available with a brilliant, new lighting technology. Coaxial Speaker Technology Every M6 coaxial loudspeaker starts with a long-excursion woofer designed with JL Audio’s proprietary motor, suspension and cone modeling systems to yield superior frequency response, smooth mid-range dispersion and linear performance at all listening levels. JL Audio’s acoustics laboratory in Miramar, Florida performs extensive testing on multiple generations of prototypes to refine every design and extract maximum performance. Matching Silk-Dome Tweeters Since the different size woofers in the M6 coaxials have different upper frequency response limits, each size pairs with its own specially designed, matching silk dome tweeter (0.8, 1.0, or 1.25-inch diameter). Each of these tweeters is precisely tuned via a rear cavity that optimizes its mid-range extension to seamlessly transition with its matching woofer. The result is smooth, evenly dispersed sound throughout the critical crossover region, making the overall sonic presentation clean and clear. Advanced Built-In Crossover Networks Crossover networks are a critical part of the M6 coaxial speakers’ acoustic design and are considerably more sophisticated than those used in most marine coaxial speakers. The M6-650X employs a 1st order low-pass and 2nd order high-pass filter, while the M6-770X and M6-880X apply a 2nd order low-pass and 3rd order high-pass filter. Each crossover network also employs an electronic tweeter protection circuitto minimize the possibility of tweeter failure. The multiple components required inthese crossovers are laid out on a ring-shaped circuit board that is built into each speaker’s terminal assembly, ensuring that the crossover is secure and protected from the elements.
