ADVISORY
Terra AC Classic and FIVE Series loudspeakers can be installed for a variety of indoor and outdoor applications. If you’re
not completely comfortable with speaker wiring, amplifier connections, or other aspects of the physical installation
please hire an audio/video installation professional and/or a licensed electrician to assure proper and safe installation.
During installation be sure to carefully follow all applicable local codes and laws.
IMPORTANT NOTE
When choosing a location for placement be sure to select an area that does not flood as these speakers are not designed to be submerged. Also avoid placing
them directly over a source of high heat, like sauna heating elements or steam room vents.
SPEAKER LOCATION, BASS PERFORMANCE
Speaker placement impacts distribution of sound and bass performance. Terra AC Classic and FIVE series speakers have exceptionally broad dis-
persion of sound and can be placed fairly far apart while providing excellent coverage. You can place them up to 8 feet apart without concern
about serious “dead spots”.
More coverage information is located on the back of this sheet.
Simply mounting the speakers on a wall or low, close to the ground – rather than up on a post in free space – will increase the apparent bass
output of the speaker. Since outdoor speakers are almost always mounted in the former way, Terra speakers are acoustically balanced to provide
the smoothest response in such locations, taking into account the bass “bump” caused by adjacent surfaces. If you wish to maximize the speaker’s
bass output, place them in corners, along the base of a wall or directly under an eave (every directly adjacent surface will double the apparent
bass produced by each speaker). Of course, the best way to dramatically enhance outdoor bass performance is by adding one or more Terra AC
SUB all-climate subwoofers to the system.
GENERAL INSTALLATION TIPS
1. In general we recommend most indoor or outdoor distributed audio sound systems be configured for mono operation, not stereo, as rarely is
anyone listening in “the stereo sweet spot”. This makes 70/100 Volt system design all the more practical for multi-speaker installations.
2. Use a minimum of 16ga. twin conductor for short wire runs. Over 50 feet use a minimum of 14ga. Outdoors be sure to use burial grade wire.
If you’re pulling wire through walls be sure to use wire rated for in wall use (CL2 or CL3). If possible, we recommend running the wires through
burial grade conduit for all underground runs.
3. 70/100 Volt systems can use lighter gauge wiring but we still recommend a minimum of 18ga.
4. 100 Volt system wattage settings are halved from the marked values. They become 8, 16, 32 and 64. Do not use the 64 watt setting. See sec-
ond page for more details.
5. Optimum reliability dictates the use of waterproof outdoor junction boxes for all connections, if possible.
6. The best connections will be made either by soldering and shrink wrapping or using silicone filled all weather connectors like the Terra BVS-2.
7. If you’re mounting speakers on a building, try to have at least one pair of bracket screws driven into a stud or header. If you’re not sure about
the location of the studs, use a “stud finder,” that indicates stud positions.
8. If the smoothest overall sonic performance is important, locate the speakers at least 18" from corners, adjacent walls and ceilings.
9. For installations with sensitive neighbors mount the speakers low and aim them up towards the listeners (avoiding reflective surfaces) or mount
speakers high and aim them down (where shrubbery and such will absorb sound). You should also consider placing the speakers around the pe-
rimeter of the listening area facing inwards as opposed to facing out.
10. For areas where serious listening may occur, locating the speakers 6 to 8 feet apart and aimed at the primary listening area will optimize per-
formance. Also, stereo should be considered for these spaces.
