The V30 guitar speaker features complex overtones,

Back in 1986 a new breed of hard rock player was on the rise. To meet the demands of the players and their increasingly ‘hot-rodded’ amplifiers we set out to develop a modern guitar speaker capable of handling much more power and overdrive. To achieve this we coupled our ‘H’ magnet (the closest in performance to Alnico) with a new cone and voice coil employing contemporary materials.
 Our most revealing speaker the Vintage 30 features enormously detailed and complex overtones a warm low-end a famously rich vocal mid-range and a beautifully detailed top-end. Used singly to reveal the complexities in hand- wired boutique amps or in quartets for a wonderfully intricate vintage 3D crunch the Vintage 30 sound has been captured on thousands of recordings from a diverse range of notable players including Slash Steve Stevens and Peter Frampton.
