M&K IW28S Subwoofer
More than four decades of experience and insight have been applied to the design of this truly invisible subwoofer, based on high-performance 8” woofers specially developed for the M&K Sound V Series subwoofers and ingeniously adapted to meet the extreme demands of shallow, flush-mount installation while delivering the quantity and quality of deep bass that consumers and professionals expect from M&K Sound.
The specially tuned, ultra-fast, mass-loaded dual drivers employ aluminum shorting rings for minimal voice coil distortion at long excursion. Highly rigid paper pulp cones with high inner damping ensure stability at extreme levels and low resonance. The ultra-linear solid ferrite magnet system provides effective dissipation of heat from the voice coil to prevent power compression from limiting the acoustic output of the system.
The drivers are installed in full contact with the front baffle and the rear of the box for ideal mechanical stability to minimise driver resonances that can occur due to the limited volume of an In-Wall enclosure.
