The Vector is a truly weather-resistant coincident axis two-way speaker. It's capable of prodigious output to cut through the engine and wake noise. Specially designed compression driver and horn are able to direct the loudest sounds in a very tightly controlled pattern of dispersion for maximum musical output. Engineered for the long throw from the boat to the wakeboarder, the horn concentrates the mid and high frequency energy necessary to cut above the noise and deliver music to your exact location without wasting the acoustical energy in areas where it's not needed. 8" driver combines a mica-filled polypropylene cone and Santoprene surround for durability under extreme weather. UV-resistant DuraTech enclosure. Two 1" coaxially mounted compression horn drivers. 360° rotating clamp fits 1.75" to 2.875" tubing. Tower wire harness sold separately.
