When entertaining outdoors, what you really want is smooth, even sound throughout the entire listening area. To achieve this goal, Niles makes two basic types of weatherproof outdoor loudspeakers: conventional stereo and stereo input (SI). Conventional stereo is the two-speaker, the left and right setup that we all know and love. Not as well known is stereo input. These loudspeakers provide blended stereo sound from a single enclosure. When designing outdoor systems, it really helps to understand the advantages of each and what all the options are. Why settle for so-so when you can have a system that really rocks?
Scenario 1: Stereo sound for a patio with a central, fixed listening area
- In this application, the setup is a typical patio with a relatively fixed listening area: a table and chairs where people gather. Since most of the listening will be in this one area, the best solution is a pair of Niles OS Indoor/Outdoor Loudspeakers mounted on the wall wired to play stereo sound. Since the listeners are in the "sweet spot," they are positioned to enjoy the best possible stereo imaging. The sound will be spacious with a realistic soundstage of music filling the area.
Scenario 2: Blended stereo for a patio with multiple listening areas
- What happens if you step out of the "sweet spot?" This setup has multiple listening areas: people mingling at different spots on the deck. Sometimes, these listening areas are not located in the stereo "sweet spot" described in Scenario 1, so the listener's ability to hear the stereo image is diminished because of their proximity to just one speaker. One speaker becomes dominant, masking the sound of the other.
- The solution is a pair of Niles stereo input (SI) loudspeakers. SI loudspeakers produce blended stereo sound from a single cabinet by utilizing two properly positioned tweeters and a dual voice coil woofer. The stereo imaging and spaciousness may not be as good as the "sweet spot" using conventional stereo loudspeakers, but you get even coverage of stereo-like sound. There are SI versions of all Niles outdoor loudspeakers -- OS, Rocks, and Planters -- so you have plenty of designs to choose from.
Scenario 3: Background music for a patio with multiple listening areas
- In setups where the music is mainly played in the background or where people are constantly moving, consider wiring the loudspeakers for mono (non-stereo) sound. In this scenario, each loudspeaker plays a combination of both stereo channels, eliminating the sweet spot limitations of stereo. Of course you'll lose the stereo effects in the music, but for background listening it's a reasonable compromise.
- To wire for mono sound, the zone preamp outputs of the multizone receiver are connected to a separate power amplifier using two "Y" adapters. This effectively combines the left and right channels into one. Or you can use a Niles 12-Channel Systems Integration AmplifierTM. It provides a simple way to configure channels for stereo or mono (L + R).
