The LS608 incorporates efficient quasi-horn loading on its 1400-Watt 18″ driver to combine the best of both worlds – smooth, deep, powerful bass and remarkable compactness. Suitable for touring or fixed installations, the cabinet is constructed of 15mm 11-ply Baltic Birch with heavy internal bracing for reduced resonance and better durability, all covered in rugged black carpeting. An optional finish of black ultrathane paint (LS608B) is also available. Hardware includes metal corner protectors and a heavy-gauge metal grille. Amp hook-ups and sub inter-connections are made simple with parallel pairs of 1/4″ and Speakon™.connectors. Additionally, the Speakons™ are regulated by a configuration switch which allows instant reversal of the pinouts for easy single-wire hook-up using optional four-wire Speakon™ cables.
