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.
Center Channel Speaker (RM8C x 1): The RM87 home theater
speaker system features one satellite center-channel speaker. The RM87's center
channel speaker consists of two 2-1/2" dynamic balance composite cone drivers
and a 3/4" silk/polymer composite dome tweeter for full-bodied sound.
Wide Dispersion Array Front Satellites (RM8 x 2): The RM87
home theater speaker system features two front satellite speakers. The RM87's
wide dispersion array satellite speakers create a more enveloping, less
localizable surround effect because the speakers drivers are mounted on opposing
baffles for a broader and larger front-stage sound field and a more immersive
and atmospheric surround field. The speaker features two 2-1/2" dynamic balance
composite drivers mounted on different sides of the speaker's enclosure and one
3/4" silk/polymer composite dome tweeter for rich, real life imaging.
Direct Radiating Rear Satellites (RM7 x 4): The RM87 home
theater speaker system features four rear satellite speakers. The RM87's direct
radiating satellite speakers consist of one 2-1/2 dynamic balance composite cone
drivers and a 1/2" dynamic balance composite semi-dome tweeter for distortion
free and smooth sound.
Enclosure Design
Enclosure: The RM87 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.
Connections
Speaker Terminals: The spring clip terminals located on the
rear of the direct radiating satellite speakers and center channel and on the
bottom of the array satellite speakers will accept pin connectors and bare wire.
Mounting Options
Video Shielded: The RM87 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 Polk Audio RM87 home theater speaker
system offers various mounting options for each speaker.
- Mounting the Front Speakers: The RM87 wide dispersion array
satellite speakers feature a removable base which allows you to place the
speakers on a shelf or table top. The base adds approximately 0.4375" to the
height of the speaker. The array satellite speakers can also be wall mounted
using the supplied wall mount bracket which lets you rotate the speaker
horizontally.
- Mounting Center-Channel: The RM87 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.
- Mounting the Rear Speakers: The RM87 direct radiating 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.
Note: The RM87's front and rear satellite speakers are compatible
with Polk's SA-3 floor speaker-stands (107SA3B,
sold separately).
