Key Features at a Glance

  • A complete 5.1 home theater speaker system that includes four RM7 Satellite speakers, a RM7C center channel and a powered subwoofer.
  • The 8-inch downward firing powered subwoofer is small enough to be discretely hidden away yet powerful enough to put you in the action.
  • Heavy-duty, non-resonant composite enclosures create the ideal décor accent.
  • Three-sided cabinet design minimizes the visual impact on walls and shelves.
  • All RM speakers come in an elegant black high-gloss finish.
  • Accessories include flexible wall brackets for all speakers and shelf cradle for center channel.

Reuleaux Triangular Polygon Shaped Enclosure

These stunning little speakers are a sophisticated work of acoustic alchemy. With Reuleaux Triangular Polygon shaped enclosures, these speakers not only are pretty cool but also extremely strong. Moreover, the speakers' geometry is acoustically ideal for minimizing resonances and standing waves inside the speaker. This eliminates the "boominess" that makes other small speakers sound "muddy", and delivers superior midrange performance and lifelike imaging.

Composite Driver Technology

Working in tandem with the shape of the compact enclosures are specially engineered drivers made from strong composite materials. Polk Audio's exclusive Dynamic Balance technology scientifically tunes these driver materials to produce an excellent flat frequency response, with revealing detail, transparent imaging and the ability to play loud without strain, something you won't find in other small speaker systems. RM sound is always clean, clear and effortless.

Anti-Diffraction Baffle

Exhaustively tested and modeled to produce the sophisticated acoustic sculpting, the anti-diffraction baffle delivers the largest possible dispersion pattern with virtually no edge diffraction or distortion. The wide, lifelike soundstage proves that you can have small speakers without sacrificing big sound.

Powerful Bass Blending

The compact 50-watt powered subwoofer features an 8" long-throw dynamic balance poly composite driver. The long driver excursion and excellent linearity produce big, musical bass. A built-in power amp with active crossover offers the control you need for real home theater thrills.

Multiple Mounting Options

Put them on the TV stand. Put the center channel speaker right on the TV. Put them on stands next to the TV. Hang the speakers on the walls. Use articulating brackets to aim them perfectly. The RM 705 satellites weigh just 3 lbs., so you can put them virtually anywhere and move them easily.
