The PSB Alpha T20 uses a ¾ inch (19mm) black anodized aluminium dome tweeter to extend the high-frequency response further than any Alpha before while lowering distortion to deliver a lush soundstage full of details. Unlike lesser designs at this price, all of the new Alpha Series tweeters employ ferrofluid cooling to prevent dynamic compression and a neodymium magnet for high sensitivity.
