Their attractive, rotationally molded Polypropylene enclosures simultaneously keep the elements at bay while reducing sonic distortion. As with all Terra speakers, every component part of the AC Series has been carefully designed and manufactured to deliver reliable sound for years without maintenance or special care. Terra’s Location Balanced Sound™ assures you of excellent performance whenever the speakers are mounted to a building or other surface. And our universal mounting bracket makes it easy to locate the AC Series most anywhere you might want to.

FAQ

  • Do Terra speakers carry any certifications for all-climate capability?

    Terra speakers have been tested to meet IP67 ratings for dust and moisture exposure. Additionally they meet or exceed the basic requirements for environmental exposure described in MIL-STD-810G, which addresses a broad range of adverse environmental conditions.

    Our speakers can be exposed to salt spray and chlorine mist in addition to operating at temperatures ranging from 5 to 175 degrees Fahrenheit.

  • Can Terra speakers be fully exposed to the elements? Define “fully exposed” and “all weather”.

    Every Terra speaker is designed to be exposed to the elements and will withstand such exposure for years (Limited Lifetime Warranty). Even our CA series in-wall/in-ceiling models can be installed with their fronts exposed to the elements. CA series models are also rated to be installed in “difficult” indoor locations such as saunas, steam rooms and pool houses. Unlike so many other “outdoor” speakers, Terra products are built to marine grade standards to withstand the rigors of full environmental exposure (including salt) over the long haul while providing exceptional sound reproduction all the while.

  • Do you make a 70 volt subwoofer?

    The AC.SUB is normally shipped as an 8 Ohm unit. We do have an option for a high power 400 Watt 70 volt transformer for those applications where a 70 volt subwoofer is needed.

  • Are there many options for mounting the AC series with the included brackets?

    AC brackets are pre-punched with lots of screw holes and slots. They offer dozens of possible mounting solutions. The bracket corners are angled so they will easily fit up tight into 90-degree building corners if desired. We sell a horizontal PVC pipe mount that mates with the bracket too.

  • Can the AC and LS be used in commercial applications?

    Absolutely! Restaurants, hotels, bars, shopping malls and anywhere that high performance high reliability all-climate speakers are required Terra speakers make an ideal solution. And their Limited Lifetime Warranty is a real benefit in such instances.

  • Does the AC SUBe include a crossover?

    No, the AC SUBe is a passive device that requires an external crossover and amplifier. There are many such devices on the market, mostly commercial “pro sound” units. We sell the Crown™ CDi series of amplifiers that offer great sound, high power and superb system flexibility including built-in EQ, crossovers, limiters and more. We pre-program them to optimize their performance with Terra speakers.

  • How much area coverage should I estimate for each AC/LS speaker in an installation?

    First you have to determine with the client whether they’re looking for background or foreground sound. Background is low level and unobtrusive. Foreground is louder for more entertainment but can interfere with conversations in the areas immediately adjacent to the speakers. What is the goal with the system? Will anyone actually listen to music with it. Is it being used with an outdoor TV for movies, etc.? Spend some time and effort to understand the goals and desires of the client.

    For background coverage you can estimate each Terra AC/LS series 5.25-inch driver satellite speaker to cover an area of 150 sq. feet (a 10 x 15 area, for example). For foreground use we would suggest limiting each 5.25-inch speaker to about 100 sq. feet (10 x 10). The AC 6.5-inch driver models are capable of covering approximately a 15-20% larger areas.

    Of course, these are just general suggestions as the sound will cover more area than listed above, but start to fall off as you move away. As always we shy away from omni-directional speakers because their output falls off more rapidly in any given direction and there’s a much greater risk of disturbing the neighbors. Remember, more speakers, closely spaced, aimed inwards, towards the coverage area will always give the best results with the smoothest coverage and least bleed over towards the neighbors. And you won’t have to turn the system up too loud to get excellent sound quality.

    If there’s an outdoor theater involved you’ll want to be careful to place speakers to the left, right and center of the screen. If possible, try to keep them at or close to ear height and no more than 3-4 feet away from the edge of the screen. Since you’re dealing with “the great outdoors” we would suggest you use the largest AC series model that the client will agree to and definitely include a nearby AC.SUB or two.

    The AC.SUB can deliver good bass performance to an area approximately 30 x 40 for background and 20 x 30 for foreground listening. Just like an indoor subwoofer, if you install the AC.SUB directly adjacent to a building wall (or two, if a corner is available) you’ll increase its apparent output significantly. And outdoors there’s no worries about standing waves unless your seated between two or more closely spaced buildings.

  • Is there any way to reduce the possibility of theft?

    We do offer a simple kit that includes a security screw to be installed through one of the end-caps that hold the AC series models to their brackets. These will slow down a thief and make it more difficult to remove the speaker
