We live in the Age of Retro. Chrysler's Hemi engine has roared back with a vengeance, Peter Jackson is busily working on his souped-up King Kong, and Polk Audio is reintroducing its legendary Monitor line. The original mid-'70s-era Monitor Series set a high standard for performance and put Polk on the map, helping turn it into one of the largest speaker companies in the United States. The Monitor 30, the new lineup's entry-level bookshelf model ($239 per pair), may not have the same impact, but it's certainly a solid value in the compact class. Standing 11 inches high and 7 inches wide and prefitted with a metal bracket for easy wall mounting, the styling of the 9-pound Polk Audio Monitor 30 doesn't stray too far from the classic box-speaker form, but the bright titanium baffle and curved grille add 21st-century flair. After you remove the grilles, you'll notice the engineers have inverted the typical tweeter-on-top-woofer-on-the-bottom alignment. The Model 30 is available in two styles: faux cherry veneer or black finish.
The Monitor Series includes a larger bookshelf model (the Monitor 40), three towers, two center speakers, and two subwoofers. For this review we partnered two pairs of Monitor 30s with Polk's smaller CS1 center and the subwoofer. The complete 5.1 system we tested retails for $879, but you can mix and match other Monitor models for your system. Want to go all out and surround yourself with a 7.1 Monitor ensemble? That'll run $1,118. Shop around a bit, and you'll shave at least 25 percent off those quoted retail prices.Even a cursory examination of the Polk Audio Monitor 30 will reveal that Polk's build-quality standards outpace the competition's. The Monitor 30 offers a larger than average 5.25-inch composite woofer mated to a 1-inch silk/polymer-composite dome tweeter. The nonresonant 0.75-inch-thick MDF (medium-density fiberboard) cabinet construction is rock solid, and the internal crossover uses high-quality parts.
The speaker's double set of heavy-duty connectors offer the possibility of biwiring (attaching two sets of wire to each speaker) or biamping (using two amp channels to drive each Monitor 30). These upgrades can result in improved sound quality over that of everyday single-wire, single-amp operation. The five-way binding posts accept bare wire, banana jacks, U-shaped spades, or pins.For our initial music auditions, we listened to the Polk Audio Monitor 30s without a subwoofer. Singer/songwriter Ben Weaver's haunting new CD, Stories Under Nails, sounded so detailed that Weaver's guitars and banjos jumped out of the speakers. Weaver's whiskey-soaked vocals sounded a little lightweight in our large listening room, but in more intimate spaces--say under 200 square feet--the Monitor 30s' bass will sound reasonably well balanced.
