Get rid of the tin can
If even Barry White sounds like he's talking in a tin can, you're long overdue for a subwoofer. Make your home audio setup the best it can be by supplementing your theater system with dynamic, rich bass that fills our all the details in your favorite audio. The new TSi Series PSW110 powered subwoofer from Polk Audio delivers powerful, accurate and musical bass. Built for power and value, the PSW110 represents a continuing refinement of the highly regarded TSi Series and a great introduction to visceral home theater bass performance.
Like kryptonite for distortion
Distortion is an audiophile's nemesis numero uno. Distortion — or interference in the reproduction of an audio signal —Ńhas a variety of sources, including driver construction, motor movement, circuitry performance, and cabinet resonance. Polk's PSW110 powered subwoofer sports a variety of design innovations that minimize these sources of distortion, thereby maximizing your home audio experience. Let's start with the PSW110's Klippel-optimized driver. The folks at Polk use a laser Klippel Distortion Analyzer to optimize motor structure, voice coil alignment, and suspension to achieve symmetrical driver movement. The more symmetrical and consistent a driver's motion is, the less distortion of sound that results. Klippel analysis assures a consistent, symmetrical driver movement for cleaner, clearer low-frequency performance.
Dynamic Balance for reduced distortion, enhanced performance
In our exploration of the multitude of ways in which the PSW110 combats distortion, let's look now at another laser-based technology used by Polk — Dynamic Balance®. This technology uses laser imaging to create the right combinations of materials, driver geometry, and construction techniques to dramatically reduce the 10" driver's resonance while also producing flat frequency response, sharp detail, transparency, and dynamic wide-range audio reproduction.
Zapping distortion at its electronic source
Interference rears its head in a variety of ways. Even the sound waves produced by a loudspeaker itself can play a part in distorting the audio signal and the sound that is ultimately produced. Reducing interference and distortion that might result from the sound produced at high volume levels, the PSW110's compression circuitry maintains signal integrity for high-fidelity audio reproduction.
Brace yourself
As a final measure toward controlling sources of distortion, the PSW110 features a non-resonant MDF (medium-density fiberboard) cabinet construction using internal bracing for low distortion, deep bass impact, and superior detail, accuracy, and musicality.
Get down with down-firing bass
As a vented-enclosure subwoofer (also known as a bass-reflex sub), the PSW110 allows you to experience enhanced low-frequency reproduction out of a smaller enclosure. Vented systems use the sound produced at the rear side of the diaphragm to increase the efficiency of the system at low frequencies by taking advantage of the resonance of ports or vents designed into the enclosure. The air mass in the cylindrical ports resonates in response to the movement of the air behind the diaphragm within the enclosure, similar to the way that the air in a glass bottle resonates when you blow air across its mouth. Your new PSW110's downward-firing port delivers more bass impact while simultaneously allowing for a more modest enclosure size that won't dominate space in your living room.
Power and versatility
For bass performance that seamlessly integrates with your home audio system and delivers clear, impacting low-frequency reproduction, look to powered subwoofer systems with multiple input options. The Polk Audio PSW110 uses a built-in high-current class A/B amplifier, offering 100W of clean, low-distortion power for all your bass needs. Featuring both line- and speaker-level inputs, as well as an unfiltered LFE input for use with low-pass filtered subwoofer output jacks, the PSW110 gives you optimal connectivity options for incorporating this Polk subwoofer into your current system. Finally, a variety of features, including adjustable low-pass crossover, phase switch, volume control, and auto on/off circuitry give you control over bass output and the sub's blending characteristics with your front stage speakers.
The finishing touches — cables
Go one step further in your quest to reach the pinnacle of home audio. A high-performance sub like your new Polk Audio PSW110 can only help your home audio system reach its full potential if it is receiving a quality, high-integrity audio signal. Audio cables — chosen specifically for the needs of your system — deliver the ability to maximize your PSW110Õs potential.
