Description

JL Audio M3-770X-C-GW – 7.7″ Marine Coaxial Speakers

Specially designed and built for real marine use.

Description

The oversized 7.7″ design of the M3-770X results in increased efficiency (more power for a given wattage). This gives them the ability to play louder and cleaner at higher volumes than smaller speakers.

The woofer design is optimized to operate with a large volume of air behind it (at least 2 cu ft / 57 l). Using this coaxial system in less space will compromise its low frequency performance.

A 0.75-inch pure silk dome tweeter, specially treated to withstand the marine environment, handles high-frequency duties. Silk was chosen for its lightness, excellent damping properties and smooth response characteristics.

Although M3-770X coaxial systems can be operated with as little as 20W per channel, for best audio performance we recommend amplifiers capable of between 75 and 100W continuous power per channel.
