Martin-audio C6.8T 天花喇叭

Featuring a 6.5" (165mm) bass driver and a 0.8" (19mm) dome tweeter, The C6.8T is ideal for flush mounted applications where full frequency performance and wide dispersion are required from a compact, ported enclosure. The side-by-side arrangement of the drive units maintains smooth response up to 75° off-axis and makes the C6.8T perfectly suited for use in low ceilings, where its broad coverage means that fewer units will be required to deliver premium sound over the required listening area. The C6.8T features a 4-point mounting system for ease of installation and a rising clamp plug and socket permit easy pre-wiring with up to 2.5mm2 conductors.
