Overview
Polk Audio designed this RM series satellite to add rear channels to its existing surround systems. A small polymer cone midrange and silk dome tweeter share a mineral-filled polypropylene enclosure with a PowerPort vent, and keyhole slots let it hang flat on a wall.
Filling out rear effects to match an existing Polk system is its whole purpose, and the PowerPort helps the midrange meet the subwoofer without a gap. The listing gives two midrange sizes, and it only makes sense alongside a sub.
Who it's for
Polk RM surround owners who want back surround channels behind the seating. Listeners without a subwoofer, or a receiver with extra channels, have no use for it.
Pros and cons
- Wide stated frequency range
- PowerPort smooths the hand-off to the sub
- Built-in keyhole wall mounting
- Long parts and labor warranty
- Sold singly, a pair means two orders
- Midrange size listed two ways
- Needs a subwoofer for full range
Performance notes
The PowerPort vent extends lower midrange output so voices sound full where the satellite hands off to the sub. The integrated baffle and grille spread sound widely across the seating area. Matching the rest of an RM system avoids tonal shifts as effects move around the room.
