Overview

Our take on the Polk Audio RM75 Home Theater Speaker System

The Polk RM75 offers exciting wraparound audio effects in a sleek, modern design. These compact, wall-mountable satellite speakers fit beautifully in most rooms, and they're a great cosmetic match for a flat-panel TV. You get two front speakers, one center channel, and two surrounds. Just add a Polk powered subwoofer to complete the system and enjoy full, detailed home theater sound.

Each stylishly sculpted speaker sports a heavy-duty, non-resonant composite enclosure. The included wall-mount brackets let you pivot the speakers up to 180 degrees, so you can easily aim them toward your listening position for the best possible performance.

and I'm glad he did. You have to add a subwoofer to complete the package - the only criticism I can come up with. Great sound - huge improvement over the "simulated surround sound" single speaker+subwoofer option I scrapped recently. As always, great execution by the folks at Crutchfield.

    Product Research

    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.

    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 lifelike imaging.

    Enclosure Design

    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.

    Connections

    Speaker Terminals: The spring clip terminals located on the rear of the speakers will accept pin connectors and bare wire.

    Mounting Options

    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.
