Get to know this product.

Like all Russound speakers, Outdoor Speakers combine acoustic technology with durability and will provide years of musical enjoyment.

The Acclaim 5 Series line provides solutions for background music and dedicated music listening. They combine premium acoustic materials with advanced drivers to deliver exceptional performance in every application.

A key benefit to using these speakers is the high-efficiency design, which means less amplification power is needed - less power does not mean quiet!

The speaker comes with two installation options: a free-standing base and a bracket mount. The base attaches to one end of the speaker and provides a stable vertical placement option for shelf or table. The bracket mount accommodates flat surface and corner locations, plus the bracket accepts U-bolts for attaching the speaker to a pole. Once the bracket is installed, the speaker slips into slots on the bracket so you don’t have to hold the speaker in place while securing it. The bracket and speaker have knurls for secure alignment to the desired angle.

Designed and built to withstand the rigors of outdoor environments, the 5 Series outdoor speakers will provide years of trouble-free service. They work in a wide range of temperatures and be unaffected by extremes of humidity. A corrosion-resistant aluminum grille and bracket coupled with the speaker’s rugged environmental design assures durability in any kind of weather. Sealed enclosure offers greater durability against the environment's rigors.

  • Rugged design for all-season enjoyment
  • Heavy-duty mounting bracket for sturdy installations
  • 1" Teteron Tweeter for crisp, clear high frequency reproduction
  • Bookshelf Foot included for use on a shelf or table-top
  • Gold-Plated push terminals for easy, corrosion-free wiring connections
