9. ers Thank you for purchasing Atlantic Technology products Our speaker sys tems have been designed to deliver exceptional sound and value We hope you like what you hear from them and are happy with your decision to buy them Please take a few moments to read these instructions They re intended not only to tell you how to mount the speakers but how to get the best perfor mance from them Speaker Placement Instruction Manual Important Considerations Before Installation Recommended Wire Sizes The longer the wire run the heavier the wire should be Use the following recommendations as a guide for your installation And if youre in doubt remember that it never hurts to get the next heavier grade of wire Also note that lower gauge numbers equal heavier wire sizes Wire Run Wire Gauge lt 15 ft 16 ga 15 to 30 ft 14 ga gt 30 to 50 ft 12 ga Location Considerations A major determinant of any speaker s sound quality is its location in the room With in wall speakers there are fewer placement options than with free standing speakers so giving some thought to location can really pay off Our In Wall Theater Systems have been designed to minimize the det rimental effects wall mounting can have on sound so they sound better than conventional in wall speakers Room Acoustics Hard surfaces create lots of sound reflections in the room while soft surfaces tend to absorb sound Note the speakers location in terms
10. he installation of IWTS speakers The IWTS speaker can be easily mounted in most any standard wall mate rial from to 1 inches thick Its rotating wall clamps sometimes called dog legs firmly fix it to the wall surface after the proper cutout has been made Here are some important precautions to take before mounting Keep the sides of the actual mounting hole at least inch away from beams or studs to ensure that the clamps have adequate room to rotate A stud or other obstruction that s too close will stop them from properly doing their job Wall cavity size will affect the bass and midrange performance of any in wall speaker The IWTS 5 LCR is designed to play optimally in a 0 5 to 1 0 cubic foot space measured before wall insulation is inserted and the IWTS 10 LCR in a 0 75 to 1 5 cubic foot space Cubic dimensions can be determined by multiplying the length x width x height of the cavity A larger cavity won t hurt but a smaller one will negatively impact the bass and midrange response of the system Some of the sound from the speaker will transmit to the space on the other side of the wall cavity If this is a major concern you can build a box within the wall that provides the required cubic volume Please note that there is very little room behind the drivers in a standard 2 x 4 wall cavity there s only 1 4 inch so the back of any enclosure box must be made from thin material Typically then the back wall material
