Polk Audio TSx Series Home Theater Speakers - eCoustics.com
Polk Audio has updated its high-performance, high-value TSi speaker lineup, first released in early 2008, with the completely redesigned TSx Series home theater speakers, which offer a curvilinear cabinet design, improved bass, greater dynamic range improved imaging, better detail, and superior sensitivity.
The revamped TSx speaker line, as it’s now known, will bring with it a whole host of audio improvements, including new voicing, with an emphasis on the accurate reproduction of high frequencies that is so critical to the uncompressed high-resolution of today’s Blu-ray discs, as well as improved bass thanks to a shift from 5.25” drivers to new 6.5” specially formulated fibrous bilaminate substrate cones made of pulp infused special polymer compounds that improve stiffening without adding mass.
Polk Audio TSx 440t - feetAt the head of the line is the new TSx 550T, a flagship tower speaker featuring a 1″ Dynamic Balance Tweeter, two 5.25” midrange/mid bass drivers, in a new three-way design that includes two 8-inch low frequency drivers with a 3″ front firing flared port.
As with the TSi series, there will also be two other tower speakers in the lineup. The TSx 440T (pictured above) features the same 1″ Dynamic Balance Tweeter as the 550T, along with three 6.5″ midrange drivers and a 3″ front firing flared port. The TSx 330T, which relies on a 1” tweeter and 3″ front firing flared port, with two 6.5″ midrange drivers.
Other new models include two new bookshelf speakers — the TSx 220B featuring a 1” tweeter and 6.5” driver and TSx 110B featuring a 1” tweeter and 5.25” driver, respectively—as well as two center channel speakers, both of which feature Dynamic Balance Tweeters. The TSx 150C features the line’s 1″ Dynamic Balance Tweeter with a pair of 5.25″ midrange drivers and a 2″ inch rear firing flared port; the TSx 250C boasts a larger cabinet to make room for its pair of 6.5″ midrange drivers, and also features a 2″ inch rear firing flared port.
All of the TSx series speakers come with high-quality five-way binding post speaker connections—single connections for the center channels and bookshelves; dual bi-wirable speaker connections for the towers—and a choice of Black Oak or Cherry finishes.
“When it came time to start transitioning from TSi to the TSx line, we worked hard to make sure we didn’t make changes for changes’ sake,” says Mark Suskind, Vice President of Product Line Management at Polk Audio. “We knew what made the original line such a hit with our customers, and we never lost sight of that as we upgraded the bass, improved the high-frequency response, and refined the aesthetics of our new TSx speakers. A lot has changed, but one thing remains the same: With our love of music, Polk has always been committed to making things sound better with every product we make. These new TSx speakers continue to fulfill this promise and deliver outstanding performance at truly reasonable prices.”
