That version, the 20Tv2 ($32,000/pair) made its debut at the 2009 CES. It retains the earlier version's ribbon tweeter and midrange unit, but features two new 7" woofers, these using a cone constructed from layers of carbon-fiber, Rohacell, and glass-fiber, and said to offer a huge linear excursion. The crossover had to be redesigned around the new woofers, of course. The new speaker sounded pretty damn good at CES, driven by Boulder amplification and the impressive new Boulder 1021 CD player, and, as Wes Phillips reported earlier in this report, it also worked surprisingly well with the inexpensive Peachtree Nova amplifier.
