The Q412D Monitoring System from Quested includes a four-way active speaker plus QSB118 Sub Cabinet
Designed to be soffit-mounted main monitors for large control rooms. The system comprises four 12" low frequency drivers, one 3" mid frequency driver, and one 1.5" high frequency driver that combine to provide effortless and articulate performance with sound pressure levels of 130 dB.
The Q412 was Quested's first studio monitor to utilize four 12" bass drivers in place of the standard two 15" configuration, offering faster bass transients, less distortion, and an extended low frequency response. The monitor is supplied with a separate electronics package containing two AP1550-2 amplifier, two AP950-2 amplifiers, and the SM748 electronic crossover/loudspeaker management system. The Q412 ships with five IEC power cables.The Quested QSB118 offers extended low frequency performance. Ideal in applications where extended or high levels of LF performance are required such as music mixes, film recording and effects channels.The cabinet is constructed from 22 mm MDF with a 40 mm front baffle and cross braced for additional rigidity. The bass driver is a 457 mm (18”) unit with a 100 mm (4”), four-layer voice coil, triple rear suspension which allows an exceptionally large peak to peak movement of 50 mm.The driver has an external radial chassis and vented magnet which results in far more efficient cooling of the voice coil. The benefits of this are less power compression, increased output and improved reliability.The Q412FS Systems design is based on one of our most popular and iconic soffit mounted systems. The system has been adapted to allow for the 4212 element to sit on top of the QSB118 sub-bass and be at a perfect height for most work stations with the acoustic center at approximately 1.4m. The 4212 element is a three-way monitor utilizing dual twelve-inch radial chassis drivers.
