1.0 GENERAL INFORMATION
1.1 Introduction
This manual contains information for the installation and operation of Model ASW-518,
P/N 106511-518-4A0001, Aircraft Cabin Subwoofer.
This document includes product information such as mechanical, acoustic, and electrical
characteristics.
1.2 Purpose of Equipment
The ASW-518 is a lightweight, high power, bass reflex subwoofer module designed for
placement under B/E Aerospace luxury seat bases. The high excursion 5.25” driver is
precisely matched to the acoustically tuned enclosure resulting in high output and lower
frequency bass roll off. The motor structure of the driver is designed to be lightweight
and have low magnetic leakage compared to conventional designs. The acoustic
settings for this subwoofer are based on aircraft type and cabin configuration to provide
the finest audio available.
1.3 Design Features
The ASW-518 is designed to be as small and lightweight as possible without sacrificing
audio performance. It is only 3.5” deep. The small package allows for easy installation.
The speaker has a maximum music power rating of 50 Watt RMS (40Hz –200Hz).
The bass reflex design allows for lower frequency bass roll off. The integrated grills
protect speakers during installation. The speaker has a high efficiency driver with low
magnetic leakage precisely matched to the enclosure.
The Subwoofer is Integral part of the Alto Aviation Entertainment System (AES).

2.3 Mounting Brackets
Prior to installation, the mounting brackets must be attached to the subwoofer enclosure.
There are two options for brackets depending on which type of aircraft they are being
installed in.
2.3.1 L500 Option
This option will use (4) of the PN 200290 brackets (included with product).
2.3.1.1 Procedure
Remove the 8 screws located on the two ends (4 at each end) of the enclosure
as shown below.
Install brackets (2 at each end) using the screws that were just removed. Align all
brackets in the same orientation as shown above using a #2 Philips screw bit.
Tighten all 8 screws to 12 inch-lbs of torque.

2.3.2 L600 Option
This option will use (2) of the PN 105991-1 brackets (included with product) and (2) of
the 105991-2 brackets (included with product).
2.3.2.1 Procedure
Remove the 8 screws located on the two sides (4 on each side) of the enclosure
as shown below.
Install brackets (2 on each side) using the screws that were just removed. Align
all brackets with the open end of the mounting brackets facing the shallow end of
the enclosure as shown above using a #2 Philips screw bit.
Tighten all 8 screws to 12 inch-lbs of torque.
2.4 Wiring Requirements
Loudspeaker wiring should use twisted pair or twisted shielded pair wire. If twisted
shielded pair is used, the shield should be grounded at the amplifier end only.
Speaker wires that are too small will attenuate the signal to the speakers. Loudspeaker
wires must be sufficient so that the maximum harness resistance between the unit and
each speaker should be < .25 ohm. Harness resistance can be measured by:
Disconnect the amplifier and speaker.
Short the harness pins together at the speaker end.
Measure resistance across the speaker output pins at the amplifier end of the
harness.
