Introduction

AMT -15

Speaker Mounting

Single Speaker

The Apogee AMT loudspeakers may be deployed individually by several methods. First, the loudspeakers may be

stacked directly on one another using the built-in feet on each speaker.

Both the AMT-12 and AMT-15 may be mounted on stands using the integrated 35mm (1-3/8") stand mount on the

bottom of the enclosure. Because of the light weight of the AMT loudspeakers, plus the convenient integral handle,

one person can set up multiple speakers on stands easily and quickly.

The loudspeakers may also be suspended by attaching forged eye-bolts to the rigging points of the speakers

(Rigging point: depth 15mm, diameter M8, thread pitch 1.25mm). There are two rigging points located on the speak-

ers' top and two on the bottom. Plastic screw caps protect the rigging points. The enclosures can be suspended

from these points with stainless steel wire rope or an equivalent approved by a qualified engineer and/or your local

code enforcement office.

Note: The rigging points are only for suspending the speaker itself. Do not suspend other speakers

or equipment from the speaker's rigging points.

Multiple Speakers

The Apogee AMT loudspeakers have a coverage angle of 60 degrees horizontally by 45 degrees vertically. Should

this not be sufficient to properly cover the listening area, or if the acoustic output of a single speaker is not great

enough, multiple AMT loudspeakers may be arrayed to provide greater coverage or higher on-axis SPL. The pre-

ferred method of arraying two loudspeakers is with the Apogee Adjustable Rigging Beam Assembly (Part No. 109-

2140). The rigging beams allow for user adjustment of the splay angle between the cabinets from 0 degrees "Tight

Pack" to 30 degrees of splay.

In a Tight Pack Array, the total coverage of the array will be slightly greater than that of a single speaker. Because of

the overlap in coverage between the speakers in the Tight Pack configuration, the on-axis SPL will increase 3dB. As

the splay angle increases, the on-axis SPL will slowly decrease back to that of a single speaker and the coverage

angle will widen to a maximum of 120 degrees horizontal.

AMT -12

The AMT -12 is designed to deliver high-output

music and sound reinforcement in a lightweight

package. The 12-inch woofer has high sensitivity

to maximize amplifier output. The 1.77-inch

compression driver diaphragm, comprised of an

aluminum alloy for added strength and rigidity,

effortlessly handles the high input levels to match the

woofer. A carefully designed cross-over network

accurately filters each driver for proper matching of

phase and summation in the cross-over region.

The transition is much smoother than other loud-

speakers in this class, making the sound more

accurate and more realistic.

The AMT -15 combines the same high-output

compression driver used in the AMT-12 with a

robust 15-inch woofer. The sound quality is

enhanced further by a richer, dynamic bass response

which extends a full 10 Hz lower. The AMT-15 can fill

larger rooms with more power than competitive

models, and with much more accurate sound.
