This speaker doubles as a planter box — you get a great-looking, functional piece for your patio, plus full, rich Niles sound to liven up your cookouts and backyard ballgames. Plant flowers, herbs, or greenery in the weatherproof cabinet. The PB6Si comes with a flush-mount side grille that's naturally camouflaged. Your guests might wonder just how you're producing those great outdoor tunes.

Niles designed the PB6Si for spacious, high-fidelity sound. A 6-1/2" woofer and two custom-angled tweeters disperse crisp sound over a wide listening area. And the separate left and right channel inputs give you accurate stereo sound from just a single speaker.

Outdoor speakers let you move the party outside

Outdoor speakers are built tough -- they laugh at wind, rain and weather. Tuck a pair under your eaves and they'll pump out the tunes to keep everybody smiling and swaying at your next cookout or pool party. We also have some "rock" speakers that blend seamlessly into your landscaped lawn or garden.

Product Research

Overview: The Niles Audio PB6Si is a rectangular planter box with a built-in stereo input speaker that can be used indoors or outdoors. It is designed to accommodate live plants. This model has a weathered concrete finish; it is also available in a terra cotta finish.

Driver Technology

Drivers: The speaker has a front-firing 6-1/2" dual voice coil, injection-molded TCC (talc, carbon, and ceramic) filled polypropylene woofer with a butyl rubber surround. There are two 1" fluid-cooled, Tri-laminate Teteron tweeters, bridge-mounted at a custom angle for optimum dispersion. The dual tweeters and single woofer provide a quality stereo signal with just one speaker.

Enclosure Design

Grille: The aluminum MicroPerf grille on the speaker has hundreds of precisely-sized perforations, creating an acoustically transparent grille. The aluminum construction resists oxidation, enabling years of trouble-free operation in the harshest conditions. Both sides of the grille are painted for added protection.


Wiring: The speaker features separate left and right channel inputs. Two 2-foot, burial-rated connection cables are attached to the bottom of the planter box. Waterproof wire nuts are provided to connect your speaker wire to the speaker. The proper speaker wire gauge is determined by the length of the run:

  • 16-Gauge: Maximum Distance: 60 feet
  • 14-Gauge: Maximum Distance: 100 feet
  • 12-Gauge: Maximum Distance: 160 feet

Configuration: The speaker can be wired to be used as a single speaker, stereo input mode, or in a 2-speaker stereo mode. In the one-speaker stereo input mode, the speaker is 8 ohms. In the two-speaker stereo mode, the speaker is 4 ohms.
