Stereo from one mounting spot
The single Polk Audio Atrium 8 SDI can carry left and right channels from one outdoor mounting position. Its dual-voice-coil 6.5" Dynamic Balance woofer and two 1" aluminium dome tweeters work with a single/dual-input switch.
In dual-input mode, two amplified channels reach the same cabinet so stereo can play without mounting two enclosures. Alternatively it can serve as a left or right speaker in a conventional pair, with a second unit purchased separately. Match the input switch to the planned wiring.
Key features
- One cabinet: dual-voice-coil 6.5" woofer and two 1" tweeters
- Single/dual input for one stereo cabinet or conventional pair
- PowerPort; 45 Hz-27 kHz overall response
- About 216 x 327 x 233 mm with bracket
Placement and connections
A water-resistant PowerPort assists bass output. Overall response is 45 Hz-27 kHz, with 10-125 W recommended for each channel in stereo use. An adjustable Speed-Lock bracket and five-way terminals handle mounting and connection.
At roughly 216 x 327 x 233 mm with bracket, this cabinet is larger than Atrium 4, 5 and 6. Its main reason for use is a listening area with only one practical mounting spot. It is passive, with no Bluetooth receiver or internal amplifier.
