The first of its THX Certified releases, the Danish company says the IW500 is designed for the largest and most exclusive home cinema installations - with room volumes of up to 6,500 cu ft or 185 cu m.

As the most powerful reference loudspeaker produced by the company to date, it can be used for Left, Right, or Centre channels and placed into a behind-screen baffle wall or masonry surrounding a flat-panel display. The company says the performance characteristics are identical, leveraging increased flexibility for residential or professional installations.

Per Becher, Chief Executive Officer, M&K Sound told StereoNET:

With premium large-scale home cinemas becoming a more common phenomenon, we knew it was time to offer an in-wall loudspeaker which could accommodate the most stringent room volume requirements. We are proud to unveil the IW500 which enables our global installer network to provide unrivalled audio performance for their customers in large or exceptionally large environments.

The IW500 is a three-way loudspeaker sporting a true 92 dB of sensitivity with all its drivers mounted in a vertical line to achieve precise on- and off-axis audio performance requirements for superb imaging. THX engineers perform hundreds of scientifically formulated tests to ensure the highest possible audio with products designed for a variety of home theatre sizes. These include tests for axial frequency response, vertical and horizontal dispersion, output vs. distortion, and many more.

Steven P. Martz, Vice President of global technology partnerships, THX Ltd, added:

We are pleased to verify that the incredibly detailed audio design from M&K Sound has ensured that their IW500 met these high standards of excellence. This is a spectacular accomplishment of which they should be very proud.

The M&K IW500 offers an 80 Hz – 20 kHz (+/-1.5 dB) frequency response, pairs ideally with one or more subwoofers (such as M&K Sound's own THX Certified Dominus X15+ subwoofer), and measures a maximum SPL of greater than 117 dB and a power amplifier handling of 100 – 500 watts.

The M&K Sound IW500 release forms part of the brand's celebrations for its 50th anniversary in 2024. The IW500 in-wall loudspeaker is available now with an MSRP of $4,999 (USD). We are awaiting confirmed UK/Euro pricing.
