Caution: Exposure to extremely high noise levels can
cause permanent hearing loss.
The SP118 speaker system is capable of producing in excess of 126db SPL at 1 meter.
Continued exposure to noise levels in excess of 90db may cause permanent hearing loss.
Below is a chart of the OSHA (Occupational Safety & Health Administration) regulations for
Occupational Noise Exposure. Please note: OSHA requires hearing protection for any
work environment when the sound levels exceed those shown in Table G-16 when
measured on the A scale of a standard sound level meter at slow response.
INTRODUCTION
Thank you for purchasing ISP Technologies SP118 subwoofer. The SP118 is a high output
subwoofer for high SPL sound reinforcement applications. The SP118 was designed with a
400-watt 18-inch woofer. The SP118 was designed to connect as a passive satellite to one
of ISP Technologies Active Series Subwoofer Systems SA118 or SA115 that incorporates
a High Current D-CATpower amplifier system capable of producing upwards of 900
watts RMS.
The SP118 has a single Speakon connector for connection to an Active Series subwoofer.
The SP118 subwoofer cabinet is made of high quality 13 ply Baltic birch plywood with a
durable spray on black finish for long life.

PLACEMENT
The SP118 is designed to sit directly on the floor or stage. Do not position or mount the
cabinet where it can tip over and fall on someone. Do not attempt to mount the cabinet on
speaker stands. Do not attempt to ‘fly’ (suspend by cables, chains, ropes, etc.) the cabinet.
It was not designed for flying. Position it only on a flat, stable surface where it is not in
danger of tipping over.
Also, note that the placement of the cabinet relative to floors and walls will affect the low
frequency response. Placing it closer to the floor and walls will reinforce the low frequency
response.
A pole mount socket is provided on the top of the SP118 for mounting an ISP Active Series
Tripower 12 or Tripower 12XL three-way speaker. A standard 1.5-inch pole is required for
mounting the Tripower speaker. To avoid accidents and insure stability this pole length
should not exceed 2 feet in length.
