15" Down-Firing Marine Subwoofer

Technology header click

One of many available options in the EMB II Subwoofer series features a very contemporary down-firing cabinet design and a size that isn’t obtrusive. Built from solid aluminum and powder coated to a fine finish, the exquisite craftsmanship of this powerful subwoofer exudes luxury and performance. The EMB15-4-M is built tough to withstand extreme weather, protecting components with sealed aircraft aluminum enclosures, powder coating, aluminum constructed domes, rubber surrounds and marine grade hardware.

Internally, the EMB15-4-M utilizes a sealed design with a James 15” high excursion woofer with a patented dual gap magnet motor for high output and low distortion. An aluminum cone, Santoprene™ half-roll surround and cast aluminum frame ensure the system is ready for outdoor and marine applications. The EMB15-4-M subwoofer has been tuned to perform beyond 35Hz, (which is predominantly where most recorded bass frequencies tend to occur) all the way down to 18Hz! Because it is a high power handling passive subwoofer, we recommend pairing it with our M1000 class D amplifier which provides 1000W of clean power and features a full DSP digital processor. You can power one EMB15-4-M subwoofer with a single M1000 amplifier.
