Take a look inside this product
  • Huge Hi-Roll Surrounds that support a true long throw driver.
  • Most powered subwoofers are good for just gut-rumble and boom. Polk understands that you listen to music too so our subs are tight, precise and accurate.
  • High current 300 Watt Continuous (460 Watt Dynamic) power amplifier.
  • Adjustable low pass crossover, phase switch and volume control allows perfect blending with any main speaker.
  • Auto on/off circuit that automatically turns your subwoofer on when it senses a program signal. When no signal is present, the amplifier turns off within 15 minutes.
  • Unfiltered LFE input for use with low pass filtered subwoofer output jacks.
  • Pro-grade 5-way binding posts speaker inputs and outputs.
  • Magnetically shielded for safe, flexible placement next to a TV or video monitor.

 Technology:

Dynamic Balance® Woofer Design Polk perfected the method of analyzing a speaker's microscopic behavior with laser Interferometry. With that information in hand, Polk engineers select the ideal combination of materials, geometry and construction techniques to literally “tune out” unwanted resonance. The result is a subwoofer that delivers pure, distortion free deep bass.

Klippel Optimized Long Throw Woofer Using a state-of-the-art Klippel Distortion Analyzer, Polk engineers optimized the woofer's motor structure, voice coil alignment and suspension for longer excursion and greater linearity bringing you the best possible performance even at the most extreme listening levels.

Slot Load Venting improves bass response. The wide, long slotted vent dramatically lessens turbulence, noise and distortion, pouring out a tidal wave of precise, thunderous bass!

Rock-solid MDF construction (including a 1 inch thick front baffle) suppresses enclosure panel resonance for distortion-free, accurate response. Polk subs sound better because they're built better.

Onkyo TX-8255 Stereo Receiver


Onkyo’s TX-8255 A/V Stereo receiver: Getting back to the Basics for the Sake of Audio Quality
While new technologies come and go, the fundamentals of competent receiver design remain constant. It is best to think of it in simple terms: a power supply, an input stage, a driver stage, and an output stage that all combine to amplify signals without any loss in quality. The current that actually drives the loudspeakers comes from a power source via the receiver’s power supply. 


Superb Design
With its continued excellence in sound reproduction, Onkyo has once again created a versatile stereo receiver for the music lover in you. The TX-8255 stereo receiver offers superb functionality and dual-room capability that will be hard to match. Onkyo exclusives like Wide Range Amplifier Technology (WRAT), discrete output stage circuitry, massive power transformer, and heavy-duty extruded heat sink offer the cleanest signal on the market. 

This receiver features a high-end design approach encompassing everything form its massive power transformer design and high-current, low-impedance drive to discrete output circuitry and minimal use of negative feedback. This enables the receiver to combine tighter bass, superb transient response and enhanced presence at any volume level. 


In a Nutshell
The TX-8255 is a 2 x 50W (@8 ohms) stereo receiver capable of delivering breathtaking stereo sound. It features 5-sets of audio inputs, 2-sets of audio outputs, individual treble, bass, and balance controls, Remote Interactive (RI) port, A/B speaker switching, banana plug speaker posts, and an AM/FM tuner.
