QSB118

The Quested QSB118 is a passive 18″ subwoofer that extends the low-frequency response of a monitoring system down to the very lowest frequencies – as low as 17 Hz, depending on the room. It is ideal wherever extended or high levels of low-frequency performance are needed, such as music mixing, film recording and effects channels.

The 18″ (457 mm) bass driver, with its 4″ four-layer voice coil and triple rear suspension, allows an exceptionally large peak-to-peak cone movement of up to 50 mm. An external radial chassis and vented magnet provide highly efficient cooling of the voice coil, resulting in less power compression, increased output and improved reliability. The bass-reflex cabinet is built from 22 mm MDF with a 40 mm front baffle and is cross-braced for maximum rigidity. The QSB118 works with a wide range of full-range monitors and is an ideal partner for the Quested HQ210, Q210 and Q212. It can also be used with the Q412 where exceptional levels of low bass or a dedicated effects channel are required. An adapted version of the QSB118 forms the sub-bass section of the free-standing Q212FS and Q412FS systems.
