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

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).
