Product Details
Description
The L75 is the entry into the Sage line sources and the most flexible of them — a 48-inch planar magnetic driver with four 6-inch high operating pressure woofers, available free-standing, in-wall or on-wall, and mixable across a single installation.
The specification worth reading is the off-axis figure. Response holds 40 Hz to 20 kHz within 2 dB on axis, and 40 Hz to 18 kHz within the same 2 dB at thirty degrees off horizontal axis. Very few loudspeakers publish that number, and it is the one that determines whether the seats either side of the middle hear the same tonal balance as the middle does.
It needs an outboard active crossover with DSP and two channels of amplification per loudspeaker. Custom colours are available on the free-standing and on-wall versions, custom-length grilles on the in-wall, and anodized trim bezels on both visible variants.
