Driver Technology
Dynamic Balance: Dynamic Balance is a proprietary Polk Audio
technology using laser imaging to determine what combination of speaker
materials create the least amount of resonance. Eliminating resonance in
speakers results in a wide, smooth response and low distortion.
Composite Woofers: Each speaker has a 5-1/4" Dynamic Balance
mineral filled polymer composite woofer housed in an acoustically inert stamped
driver basket for clean midrange and deep, accurate bass. For a smoother
response and improved durability, each woofer uses a rubber surround.
Silk Tweeters: Each speaker has a 3/4" Dynamic Balance silk,
polymer composite dome tweeter with a neodymium magnet for clear, detailed
highs.
Mylar Capacitors: The speakers utilize Mylar bypass
capacitors to extend its high frequency response and improve detail and
transparency.
Timbre-Matched: The Polk R150s are designed to fit any Polk
Audio home theater or multi-channel music system for a more realistic seamless
surround sound environment.
Frequency Response: The overall frequency response is
60Hz-24kHz and the -3dB frequency response is 65-20kHz.
Enclosure Design
Bass Port: A rear-firing bass port on each speaker gives you
deep, punchy bass response.
Grilles: The speakers feature ant-diffraction grilles that
minimize grill diffraction for spacious, three-dimensional imaging.
Connections
5-Way Binding Posts: The 5-way binding posts will accept
bare wire, pin connectors, spade connectors, banana plugs, and dual banana
plugs.
Mounting Options
Video Shielded: The speakers are magnetically shielded for
safe placement near your video sources.
Applications: The R150s can be used as front or rear
speakers in your home theater application or can be used as your main stereo
pair for music listening.
Optional Speaker Stands: Polk recommends using speaker stands that are
30 to 36 inches tall. The speakers come with 4 rubber self-adhesive feet for
each speaker to help secure them in place to prevent slippage and vibration.
Wall Mounting: The speaker does not come with any type of wall-bracket
or key-hole slot for wall-mounting the speakers. To wall mount the speakers you
will need to drill into the back of the speaker cabinet or use the optional
B-Tech heavy duty side-grip wall-mounting bracket (121AM40B,
sold separately). The space to drill into the back of the cabinet is 6.1875" x
3.3125" located above the speaker terminal assembly. The bracket will need to be
able to withstand at least 10 lbs.
