Stirling Broadcast LS3/5Av3
Latest V3 version of the LS3 / 5A speakers with ultra-low distortion and improved crossover and tygan grills
It started as a personal project. Doug Stirling wanted the very best pair of LS3 / 5As that could be made. So he challenged Derek Hughes to draw on his decades of experience as a speaker designer to rethink the design. Like the Blue Skies work done at BBC Kingswood Warren in the 1970s, cost was not a consideration. But it had to be LS3 / 5As that not only met the BBC specification but also significantly improved it.
Derek started with the Stirling Broadcast LS3 / 5A V2. The V2 is a proven design that has been licensed by the BBC and has received excellent reviews. Derek had complete faith in the speaker units and the thin-walled plywood enclosure and did not believe they could be improved at this point. So he focused on his many years of experience in speaker design on the crossover. Accurately matched air core coils were introduced to avoid the saturation experienced with ferrite or iron cores. After all, the costs were not an object. Finally, Derek moved the crossover away from the vibrations associated with mounting the crossover on the front bulkhead.
The result is the Stirling Broadcast LS3 / 5A V3. Everyone who heard them told Doug he couldn't keep them to himself. We think the V3 is indeed something very special. But don't take our word for it, listen and decide for yourself.
The legendary tone of the original LS3 / 5a speakers is preserved with design modifications that keep distortion to an absolute minimum. The nominal 8 Ω impedance is lower than the 15 Ω of the original, but it is optimized for use with typical high-performance amplifiers widely available today and helps to achieve true control with a low 83 decibel sensitivity for better bass.
