T2-7.1 system uses two pairs of THX Select Certified Dipole surround effect speakers for an even more immersing sound, rendering movie effects and multi-channel music as realistically as possible. Rear effects are assigned to the dipole speakers, designed to be mounted on the side walls. The use of two silk dome, reverse facing tweeters immerses the listener in the action. Includes THX Ultra2 Certified TX-T2 tower speakers, a marvellous THX Select Certified center speaker whose ability with voices will astonish, THX Select Certified dipole speakers for side and rear effects and a hefty 200W active THX Select Certified subwoofer. Perhaps the most distinctive piece of engineering on the T2s is the proprietary 'free air' tweeter. Sitting in its own ultra-rigid, spherical, aluminium enclosure on top of the cabinets, the design can be rotated to face the listener, making room integration far easier. Free of unwanted distortion, due its shape, it delivers a clear, transparent sound with excellent dispersion. Lower down the frequency range, T2s employ 7'' Crystal fibre mid/bass drivers that comprise tightly woven fibreglass whose mechanical properties - light yet extremely stiff - deliver a linear and fast response. The magnetically shielded drivers are backed by heavy duty, powerful magnets, delivering very high efficiency levels. Each driver is housed in its own damped ported chamber for the optimum bass tuning that can be achieved at this volume. The small shape of the baffle also reduces diffractions giving an incredibly three-dimensional soundstage and far clearer stereo imaging. A similar design is found in the THX Select centre speaker which uses a rotating tweeter and one 7'' Crystal fibre woofer to deliver exceptional vocals. Completing the package is a meaty 200W active subwoofer with a 12'' long throw driver incorporating a light but rigid specially treated paper cone for fast, dynamic, transient bass with sonic accuracy.

Just like Matthew Polk's Signature Reference Theater (SRT) system, the components used in the RT Series benefit from Dynamic Balance, a technology which came out of a joint research project between Polk Audio and Johns Hopkins University. This laser imaging research enabled Polk to view on a microscopic level the entire vibrating surface of a driver or tweeter. By this method Polk was able to observe the resonances, which develop on speaker cones as they move. These resonances are the root cause of frequency response distortions. As an x-ray enables a physician to discover the root cause of a symptom and prescribe the right treatment for a cure, this laser imaging technique allowed Polk engineers to find the right combinations of high tech materials, geometry and construction techniques to tune out the offending resonances. The benefit of Dynamic Balance is the dramatic improvement in the sound quality of our speakers, which every listener can appreciate. You no longer have to choose between excellent bass and smooth, clear midrange. Now you can have it all thanks to Dynamic Balance technology. A crossover is the part of the speaker system, which directs high frequencies to the tweeter and lower range frequencies to the woofer. But crossovers can create distortion, called phase shift, which reduces clarity and degrades the ability of the speaker to create a life-like spatial image. Thanks to Dynamic Balance technology, the response of Polk's mid-woofers remains accurate at much higher frequencies than conventional drivers. This allows Polk to place the crossover frequency above the range where your ear can most easily detect phase shirt (the critical midrange). The result is clarity and imaging so outstanding that the speakers seem to melt away. You'll feel as if you're at a live performance or actually on the movie set. And the result of all these technologies? One listen will tell you. You'll notice that Polk's RT Series speakers sound a little different from other loudspeakers; the sound seems to have a more natural flow and somehow seems more at ease. You'll find them a little more alive and dynamic, with sonic images that are larger and more solid. You'll find that they offer a listening experience that puts you in touch with the full emotional power of your music and movies.

Enjoy all the performance of a high quality home theater system without sacrificing the space or aesthetics of traditional box-type speakers. This package includes all the speakers you need for powerful, dynamic surround sound and audiophile quality music reproduction. Performance compares to much more expensive speaker systems! The front left and right speakers feature a two-way design with 5.25" long-throw polypropylene cone woofers and 1/2" PEI dome tweeters, for silky smooth high frequency response up to 20KHz. The center channel matches them for a smooth, seamless transition across the soundstage. The four rear inwall speakers feature a two-way design with 5.25" long-throw polypropylene cone woofers and 1/2" PEI dome tweeters. Finally, an 8" dual voice coil inwall subwoofer adds the low end punch to enhance the action and drama of the movie experience. We recommend powering this subwoofer with its own dedicated amplifier. See our store for subwoofer amplifier options. White plastic frame and painted steel grill compliments any decor and can be painted to match your wall color. Attached mounting brackets easily mount to wall board without the need for additional hardware.
