Peterkort Square, Beaverton
The project
808 Grinds serves Hawaiian food to the Portland area, and their new Peterkort Square location needed sound to match.
They wanted a laid-back island soundtrack that's easy for staff to manage and consistent from the front door to the back patio. The space has high, open ceilings with exposed ductwork, which rules out a standard in-ceiling layout in the dining room.
A speaker for every space
We picked the right speaker for each area. In the open dining room, Episode pendant speakers hang from the ceiling structure to put the sound down where guests sit, and they blend right in with the industrial lighting.
The restrooms got flush in-ceiling speakers. The covered back patio got weather-ready surface-mount speakers, so outdoor diners get the same vibe as everyone inside.

Commercial-grade, staff-friendly
Every zone runs on an Episode 4-zone 70-volt commercial amplifier. A 70V system is the standard for restaurants and retail, because it powers a lot of speakers over long wire runs efficiently and lets each zone be set to its own level.
Music streams from Sonos, and staff control everything from an iPad mounted in an iPort wall station. Nobody has to hunt for a phone or dig through an equipment closet. We also installed a 98-inch TV as a big-screen focal point.
The result
A restaurant that sounds as good as it looks: even coverage, the right volume in every zone, and controls any employee can use on day one.
Run the room
One amp, three kinds of speaker, one iPad
Scroll through the space. At the end, you're the manager: set each zone from the wall iPad.
Pendants for the open ceiling
The dining room ceiling is high and open, so in-ceiling speakers would be too far away. Episode pendants hang down and put the music right over the tables.
Flush in-ceiling in the restrooms
Normal ceilings, so flush in-ceiling speakers keep the music going without anything on display.
Weather-ready on the patio
Surface-mount speakers under the cover of the back patio, so outdoor tables get the same island vibe.
A 98-inch focal point
We also installed a 98-inch TV, so the room has a big-screen focal point.
Staff run it from the wall
An Episode 4-zone 70V amp powers every speaker, Sonos streams the music, and an iPad on an iPort station sets each zone. Try it.
