Product Description

Q Acoustics Qi SUB 80SP Install Performance Subwoofer has been designed to be used in conjunction with other Q Acoustics install speakers to bring your sound system to the next level. Made for home cinema use, the Qi SUB 80SP features Nano Particle technology, an 8” woofer and swivel capable tweeters.


The Qi SUB 80SP is an 8” install subwoofer that features Q Acoustics original Nano Particle mass damped polypropylene low-frequency drive units that have elevated powered coil and magnet assemblies for low distortion and high transit power potential. Swivel capable silk dome mesh tweeter that protects the tweeters for fine system tuning has been combined with additional high frequency level adjustments to make this full range speaker.

High Order Crossover

A smooth frequency transition on the two and three way units has been ensured by a high order crossover, and particular attention has also been made to the mid-range frequency response and a reduction in sources of coloration of the sound.


The Q Acoustic’s Qi Sub 80SP comes with a low profile magnetic grille with optimised whole geometrics that is designed to make installation as easy as possible. The units require the minimum depth for installation, with the maximum rear depth required being 99mm.
