ECOXGEAR ExtremeTower ETB08 8" Amplified Tower Speakers + Battery Pack (Pair) – White

The ECOXGEAR ExtremeTower ETB08 is a two-speaker 8" marine tower set: one battery-powered Bluetooth-amplified speaker and one passive speaker. The amplified speaker runs from a removable, rechargeable 12V 13.4Ah lithium-ion battery pack, so the set keeps playing with the engine off and can be fitted without running 12V wiring – an optional 12V connection to the boat or vehicle (cabling included) charges the pack while the engine is running, and the included mains charger recharges it at home. The passive speaker wires to the amplified one, which carries the amplifier, Bluetooth 5.0, FM tuner and a built-in LEDCast lighting controller for the addressable RGB LEDs on both speakers, and links to up to 100 other ECOXGEAR SoundExtreme products through EcoCast. Sealed IP66 ASA enclosures and 360° rotating quick-release clamps for 38–76mm (1.5–3") bars complete the set. This is the white version; a black version is also available.

Key Features

• One battery-powered amplified speaker, one passive: the amplified speaker’s built-in amplifier drives both; the passive speaker must be wired to it (through-tower and outside-cage cables included)
• Runs on battery – 12V optional: a removable, rechargeable 12V 13.4Ah lithium-ion pack keeps the music going with the engine off; an optional 12V DC (25A) connection charges the pack while the engine runs, and a mains charger is included for charging at home
• Bluetooth 5.0 and FM tuner: long-range Bluetooth streaming from your phone, plus an FM tuner with internal antenna and a jack for an optional external FM antenna (sold separately)
• Built-in LEDCast lighting controller: addressable RGB LEDs on both speakers with no separate controller needed; control them from the speaker buttons, the included RF remotes or the SoundExtreme app for iOS and Android
• EcoCast wireless linking: pairs with up to 100 EcoCast-enabled ECOXGEAR SoundExtreme soundbars, subwoofers and speakers
• Mono or stereo: set the output to mono or left/right stereo to suit the layout
• 8" 2-way marine drivers: UV-protected polypropylene and carbon-fibre blend woofer with Santoprene rubber surround and a 1.5" titanium tweeter with double neodymium magnet; handles up to 100W RMS (250W peak)
• White LED dome light: on the amplified speaker
• IP66 waterproof and dustproof: sealed ASA enclosures for UV resistance, with water- and sand-proof Aviator and Deutsch connectors for audio and LED
• 360° rotating quick-release mount: Allen key and no-tool quick-release knob included; clamp fits 38–76mm (1.5–3") diameter bars, with salt-corrosion-resistant 316 stainless steel screws and aluminium alloy mounts
