The newly launched IAS Beaulieu 40R loudspeaker system is touted as redefining state-of-the-art transducer design whilst “offering the lowest frequency extension of any stand-mount loudspeaker system available to date”, as defined by the original 1980 Integrated Audio Systems' Beaulieu design, created by David Hall and the late Alan Willis in Southampton.

Deploying Volt's specially recreated first-generation 10-inch low fs bass/midrange unit, SEAS midrange and Accuton ceramic treble, the new loudspeaker spares no expense by utilising the pinnacle in crossover componentry with a minimalist series-wired Duelund crossover that, combined with rigid bracing and minimal critical damping, affords the system a dynamic range that, so we are told, is largely unmatched elsewhere.

We are also informed that the system nominal impedance load is 8 Ohms, with a system efficiency rated at 90dB @ 1 Watt/1 metre. Finally, useful frequency response is listed as 13 Hz – 32,000 Hz.

Set on isolation pods with a separate crossover stand and “the highest grade copper” connection posts with cotton-in-oil Duelund wiring, the signal transfer is given maximum integrity throughout the system, leading to “electrostatic-like transparency”, but with maximum, full-range bandwidth of uncompromising reach and dynamic impact.

We have a feeling that these should be on your must-hear list.

You will find IAS Beaulieu loudspeakers in the Leicester Suite on the first floor of the UK Audio Show 2023.
