High excursion 18 inch LF

The 18 inch LF transducer with its 5 inch voice coil is a high excursion design. SONODYNE customises the SLX transducers to meet the frequency, SPL and high power handling needs of the series; on the SLX 2180 the range reaches down to 30 Hz (-10 dB).

Rigid, braced plywood cabinet

The enclosure is made from 18 mm plywood with heavy internal bracing. SONODYNE finishes the SLX enclosures in multiple coats of durable stipple paint, and a powder coated perforated grille provides optimal transducer protection: roadworthy and great sounding.

System set-up

The SLX 2180 is passive and is driven from an external power amplifier through its twist-lock input; the twist-lock link connector passes the signal on to a further cabinet. SONODYNE recommends a crossover at 80 Hz - 120 Hz with an 18 - 12 dB/octave low-pass slope and a subsonic filter at 35 Hz, 24 dB/octave.
