System Components: The Polk
Audio RM75 home theater speaker system is a 5-channel speaker system that
includes four identical satellite speakers and a matching center channel
Additional Speakers: If you wish to use the RM75 for a 6 or 7channel
surround sound system, you can purchase an additional 107RM7CB single center
channel speaker or 107RM7B satellite speakers to fill out your speaker
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.
Drivers: The drivers used in the RM75 home theater speaker
package are as follows:
Satellites And Center Channel Midranges: Each satellite
speaker features a 2-1/2" dynamic balance composite cone driver while the center channel speaker features two
2-1/2" dynamic balance composite cone drivers, which are lightweight and
efficient, resulting in clear, distortion-free midrange.
Satellites and Center Channel Tweeters: Each satellite
speaker and the center channel has a high-performance
1/2" dynamic balance composite semi-dome tweeter for sweet highs and more
Enclosure: The RM75 satellite speakers and center channel
feature an acoustic suspension, non-resonant composite enclosure with a
high-gloss black finish for great looks and natural sound. The three-sided
cabinet design minimizes the visual impact on walls and shelves while the
integrated baffle and anti-diffraction grille design allows maximum sound
dispersion with minimum diffraction for superior imaging and room-filling sound.
Speaker Terminals: The spring clip terminals located on the
rear of the speakers will accept pin connectors and bare wire.
Video Shielded: The RM75 satellite speakers and center
channel are magnetically (or
video) shielded for safe placement near your TV or computer monitor without
causing picture interference.
Mounting Options: The RM75 satellite speakers can be placed
on a shelf or table top without a stand due to their flat base. The satellite
speakers can also be wall mounted using the supplied wall mount brackets which
allow the speakers to swivel horizontally. In addition, the RM75 satellite
speakers are compatible with Polk's SA-3 floor speaker-stands. The RM75 center channel can be placed on a
shelf or table top with the supplied mounting stand and can be angled up or
down. The center channel speaker can also be wall mounted using the supplied wall
mount bracket. The center channel's fixed wall mount bracket does not angle or swivel.
