Polk SurroundBars Innovate

Of the four soundbars in Polk Audio's line, two are new, and one is quite remarkable. We're talking about the SurroundBar 9000 IHT ($799). This 5.1-channel bar has three tweeters for the front channels and dedicated woofers for each of the five channels, with each driver powered by 45 watts, plus external eight-inch sub. What fascinates us is that bass frequencies from 80-200Hz are routed to all woofers in the bar. In other words, if there's significant bass content in any one of the five channels, it's routed to the other channels as well. This allows better bass handling than you'd expect in a bar. It also allows a lower crossover to the sub, an audiophile-approved 80Hz, which keeps voices from booming out of the sub. Connectivity is optical and analog, both times two, with Dolby Digital and DTS decoding. Guess what? The 9000 worked wonders with a James Taylor concert track, with realistic acoustic guitar harmonics and a vocal presentation that was crisp but not fatiguing. The other new guy is SurroundBar 5000 IHT ($399), a 2.1-channel Bluetooth bar with a pair of full-range drivers backed up by a 6.5-inch sub. Both shipping this month.
