Product Research
Features
Tower Speakers: The SoundExtreme Extreme 8" Tower Speakers (SEI-ET7708) feature an 8" 2-way driver mounted in a sealed enclosure that's designed for the marine environment. The passive tower speakers feature built-in RGB LED lighting that can illuminate the woofer cones on both speakers (controller sold separately).
Two-Way Design: The SoundExtreme tower speakers come loaded with a 1.5" titanium dome tweeter that features a double Neodymium magnet design, bridge-mounted over an 8" all-weather woofer. The 8" woofer features a UV-protected cone made with a polypropylene/carbon fiber blend and a Santoprene rubber surround. The combination provides full mid-bass sound and clear, detailed highs.
Speaker Connection: The SoundExtreme ET7708 passive 8" tower speakers include two types of connection cables for connecting into your sound system. Both 8' cables feature bare-ended speaker wire and a 3-pin LED connector on one end and a Deutsch or Aviation connector on the other end.
- Deutsch Connector: The 6-pin Deutsch connector cables provide a quick and easy connection method where the wire will be run on the outside of the tower/roll cage tubing.
- Aviation Connector: The 6-pin Aviation connector cables let you run the wire through the mounting clamps and the tower/roll cage tubing, with no visible wire.
RGB LEDs: The SoundExtreme speakers feature RGB LED lighting integrated into the enclosure, allowing the speaker cone to be illuminated via a SoundExtreme LEDCast controller or LEDCast media receiver (both sold separately). 3-Pin LED cables integrated into the 8' Deutsch and Aviation cables can be extended using the included 10' LED extension cables and Y-cable.
Mounting: The SoundExtreme speakers are designed to be mounted to wake tower or roll cage tubing ranging from 1.5" to 3.0" in diameter, and include rubber shims for a secure fit. Quick-release mounting clamps are included that provide up to 360° of rotation for optimal speaker aiming with no tools required.
