Quested QSB118 Active Subwoofer System – No Longer Available

Active stereo subwoofer system

Product Description

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 sub-woofer can be used with a variety of full range cabinets but is an ideal partner to the Quested HQ210, Q210 and Q212 and can also be used with the Q412 when exceptional levels of low bass or an effects channel is required.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
