Models 271 LR, 273m C, and 274t SR
Mounting
The 271 LR and the 274t SR speakers can be mounted in a variety of ways:
On speaker stands Optionally available Atlantic Technology speaker stands (model 176ST, available in
black or white) provide an ideal height (29" above the floor) for most rooms. Other speaker stands from may
be used, but should be of approximately the same height (29" to the base of the speaker). When using
Atlantic stands the 1/4" x 20 threaded insert in the back of the cabinet accepts the supplied bolts included in
the stand hardware package. This makes for an exceptionally secure and solid stand mounting system.
On the wall To wall mount your speakers, use the attached metal key-hole bracketson the back of the
speakers. Remember, the SR speakers should be swapped side to side to have the drivers aimed correctly.
Be sure to use a strong screw to drive into the wall, one whose head and shaft will fit within the keyhole
opening and slot. Also be sure to drive the screw well into a stud or use a mounting device (such as a molly-
bolt) that is capable of holding the weight of the speaker. Never simply drive a nail or screw into sheet rock
or other wall materials. Always follow the above guidelines for safe speaker mounting.
Note: There are several rubber pads supplied with your speakers. They are to be used as feet when the speakers sit
on a shelf, or on stands. When you use the keyhole mounts, place these pads on the lower rear of the enclosure
(remember, the enclosures are going to be mounted upside down), using a double thickness (one pad on top of
another). This will keep the speaker level and stop it from vibrating on the wall.
For greater flexibility you can use pivoting ball-and-socket wall brackets of suitable weight rating
(e.g., Omnimount 50 Series, Vogel, etc.) usually available from your local audio/video retailer. There are also
compact adjustable metal shelf style mounts from companies like Pivotelli
unobtrusive. Please contact your A/V specialist for information on these as well.
On a bookshelf Adhesive rubber feet are included to protect the speaker bottom and the shelf or cabinet.
In the wall (274t SR only) An optional Atlantic Technology in-wall mounting kit is available which includes
all the necessary hardware and trim to install a pair of 274t SR speakers recessed partially in a standard wall.
Please contact your local Atlantic Technology dealer for further information.
Listening Levels and Power Handling–IMPORTANT!
The power recommendation for these speaker components assumes that you will not operate your amplifier/
receiver in a way that produces distortion. Even rugged speakers like System 270 THX components can be
damaged by a moderately powered system driven beyond its intended capacity. The harsh amplifier
"clipping" that occurs in this situation will eventually cause damage to the speaker system. This type of
damage is cumulative and can build up over time as the amplifier is driven into overload again and again.
Such damage is easily identifiable through examination of the damaged speaker's voice coil and is not
covered by the warranty. The System 270 THX will play very loudly when provided with enough clean
power to do so. Again, consult your dealer or Atlantic Technology for additional information.
Care and Feeding of Your Speakers
Clean your speaker cabinets using a soft cloth moistened with a mild, non-abrasive glass cleaner being
careful not to wet the edges of the cabinet. Also, be careful not to get any cleaning fluids on the driver cones
or domes. It may be best to dampen the cloth with the cleaner and then wipe the speakers. After carefully
removing the grilles from the speakers by pulling them forward, gently, clean them with a quick pass from a
vacuum cleaner with a brush attachment. This should remove any dust accumulation. Re-attach them by
lining up the grille pegs and holes and pushing them firmly but carefully. Avoid placing your speakers in
direct sunlight or near a source of heat that may, over time, damage the finish.
