The Quested SB18PR is a large subwoofer from the SB range, designed for film production. It covers 20 – 200 Hz at 8 Ω and, with dimensions of 785 × 1070 × 510 mm and a weight of 90 kg, it is the largest model of the range. Like the other SB subwoofers it can be driven by the Quested SBC800 or by stand-alone amplifiers.
These extraordinary Quested subwoofers are revered by film production professionals worldwide, delivering everything from exquisite delicacy to the extreme explosive power of modern film soundtracks. They have been designed hand-in-hand with our SBC800 powerhouse amplifier, but can easily work with our stand-alone amplifiers too.
Custom 12″ and 15″ drive units, both with peak power handling of 2,000 W, 4″ voice coils and 3.5 kg magnet assemblies, deliver ground-shaking impact with incredible precision and accuracy all the way down to 20 Hz. The cage-style cabinets are super-rigid – the SB12 using 25 mm MDF and the SB15 30 mm plywood – to handle the incredible impulse energy of these superlative drive units. Our intelligent cabinet design minimises the size of the SB12 and SB15 to help discreet placement in all environments where the finest possible bass performance is required.
