Big Speaker Sound without a Big Budget

The RM7 satellite’s surprising performance belies it diminutive go-anywhere size. So small, yet so warm and full, with all the detail, clarity and transparency so vital for crisp, clear voice and music reproduction. The RM7 plays loud without strain, something you don’t find in other small speakers. The RM7 is the basis for the compact RM75 5-pack system, and it makes up the surround elements of the RM85 5-pack system. The RM705 6-pack complete home theater system is made up of five RM7 speakers plus a professionally matched powered subwoofer, and it’s the perfect small home theater system for a second bedroom, gaming setup, or even an apartment.

The RM7 Speaker Features:

The unique Reuleaux triangular polygon shape is acoustically ideal, minimizing resonances and standing waves inside the speaker to eliminate the “boominess” that makes other small speakers sound “muddy,” delivering superior midrange performance and lifelike imaging.

Advanced driver geometry and state-of-the-art crossover wiring delivers a surprisingly deep and w-i-d-e soundstage, so these RMs are the perfect solution when you’re placing the speaker against or very near the sides of your TV and still want big speaker sound without the big speakers. (RM Series speakers are magnetically shielded for safe placement close to monitors and TV.)

Special anti-diffraction baffle design produces sophisticated accoustic sculpting, with the largest possible dispersion pattern and virtually no edge diffraction or distortion.

Composite driver technology works in tandem with the enclosure shape (and Polk’s patented Dynamic Balance® tuning process) to produce excellent flat frequency response, with sharp detail, transparent imaging and the ability to play loud without any strain, something you won’t find in other small speaker systems.

Woven silk tweeters deliver superior imaging and smooth highs.

RM Series speakers weigh just 3lbs, so you can put them virtually anywhere; on stands, on shelves, on walls. RM7 & RM8 speakers come with secure wall mount brackets. The RM8 also comes with a surface mount “tripod” base.

RM7 center & RM8 center speakers are magnetically shielded for safe placement near your monitor or TV, and come with custom-designed surface mount cradles for easy placement on any flat surface.

This RM Series is mix-and-match compatible, so you can buy them in sets or in pairs and build the compact sound system of your dreams, 5.1, 6.1, 7.1 and beyond.

All RM Series speakers are professionally timbre-matched to sound perfect together in any speaker configuration.

All Polk Audio products are made using the best materials and the most advanced manufacturing techniques. They pass the industry’s most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk Audio loudspeakers are built to perform for a lifetime.
