A speaker for all seasons

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 Pro 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 Pro 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 pleasing two-channel sound from 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.

Works and looks great

Written by: Don from Florida on July 10, 2015

Crutchfield Customer Review (What's this?)

This planter/speaker was purchased for my back deck. It blends perfectly with the other terracotta planters and is a good size. My only caution to purchasers is that there is only room to plan a plant on the sides. The enclosure for the speakers takes up too much space in the center to allow for a plant and only allows for about 1 inch of soil to cover the enclosure. Plenty of room on each side for one nice plant.

Pros: Sounds great, fits two nice sized flowering plants.

Cons: Center is not plantable.

Great Outdoor Speaker

Written by: Joe from Salt Lake CIty, UT on May 23, 2013

Crutchfield Customer Review (What's this?)

Great sound for outdoors and the added look of the planter makes this one of the best entertaining investments I have made. Crutchfield's service is the only way to buy this as UPS broke 2 in shipping and Crutchfield fixed everything.

Pros: Clean looks and great sound

Cons: None as far as I can tell.

Product Research


Overview: The Niles Audio PB6Si Pro 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 features two drain-holes to allow water to drain from your plants. Available in a weathered concrete finish and terra cotta finish.

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

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', 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'
  • 14-Gauge: Maximum Distance: 100'
  • 12-Gauge: Maximum Distance: 160'

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.

Temperature Extremes: The Niles Audio PB6Si Pro planter speaker can withstand temperatures of -50° to 185° Fahrenheit.
