Atlantic Technology System 170 Music Only System Model 171 LR with subwoofer only, Mounting

Models 171 LR, 173 C, and 174 SR

The orientation of the 174 SRs is important to the proper generation of an involving and diffuse surround effect. To insure proper orientation, make sure that the RIGHT speaker is on the right side wall of the room, and the LEFT speaker is on the left side wall of the room, as you are seated facing the screen. The 174 SRs are marked RIGHT and LEFT on the back and have an arrow that should point towards the front of the room. Should you hang them on the wall, using the supplied keyhole adapters, you must turn the speakers over (hanging them “upside down”) and swap them side to side for proper orientation.

Music Only System (Model 171 LR with subwoofer only)

If you are setting up a music only system, begin with these general guidelines:

●The distance between your speakers should be approximately one-half their distance from your favorite listening position.

●If you point the front of the speakers directly towards the prime listening position, you will achieve the most precise imaging. You will also receive the maximum amount of direct radiated high frequency energy. If you have a “bright” or “hard” sounding room environment, aiming the speakers straight out into the room (or just aiming them partially towards you) may make for a more natural and pleasing sonic balance.

●The distance from each speaker to its three closest room surfaces should be different.

●In most rooms, you should not place your speakers in the corners.

The goal is to reproduce accurate musical timbre and natural sound. Additionally, a well set-up stereo pair of speakers will create excellent imaging and a cohesive representation of the soundstage. Place- ment in the room and your listening position have an enormous impact on the ultimate sound you will achieve from your system. The most important thing is to be creative! Try placing your speakers along the long wall instead of the short one. Toe the speakers in or point them straight ahead. Pull them away from the wall or push them close. Don’t be timid. You’ll find that moving your speakers, even a few inches, can dramatically change and possibly improve their sound.

Mounting

The 171 LR and the 174 SR speakers can be mounted in a variety of ways:

On speaker stands Atlantic Technology speaker stands (Model 176 ST) provide an ideal height

(29" above the floor) for most rooms. They are available in black or white (as are the 174 SR surround speakers). Speaker stands from other manufacturers 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 mount your speakers on a wall, we have supplied metal key-hole brackets that will attach to the back of the 171 LR and 174 SR speakers. You’ll need to turn the speakers over and attach the keyhole bracket to the 1/4"x20 threaded insert on the back of the enclosure so the speakers hang upside down, using the supplied 1/4"x20 bolts. As mentioned above, 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 key- hole opening and slot. Also be sure to drive the screw well into a stud or use a mounting device (such a molly-bolt) that is capable of holding the weight of the speaker. Never simply drive a nail or screw into a sheet rock or other wall materials. Always follow the above guidelines for safe speaker mounting.
