The APG TB118S is a subwoofer designed to
provide low frequencies reinforcement from
medium to high power systems.
It is equipped with one convection cooling
Neodymium 18” woofer loaded by a low pass
type double interactive chamber. This type of
load allows to limit and distribute load’s volume in
order to obtain excellent ratio on size/acoustic
power. The combination of Exclusive load (double
chamber & K-horn) brings in the usable
bandwidth an additional 4dB gain compared to
conventional direct radiation subwoofers.
Convection cooling technology used with the
neodymium woofer reduce thermal compression
by nearly 2dB which confers to the TB118S an
exceptional acoustic pressure capacity.
The ergonomics of the cabinet associated to the
use of neodymium woofer allow substantial
weight reduction. Handling is secured by
3 recessed handles. The KR100 or KR125
options features 4 rotating casters.
Operation of the TB118S requires the use of an
APG dynamic processor fro LP Series or Matrix
Series.
Subwoofer TB118S
The TB118S subwoofer is a new generation infra bass subwoofer
combining high acoustic performance with user-orientated ergonomics
design.
It is characterized by its capability of producing high sound pressure level
with accurate sound reproduction, precision and warmth.
The double interactive load offers an excellent control over the diaphragm
displacement which increase the mechanical reliability and reduce the
harmonic distortion. Therefore sound reproduction stands out compared to
conventional subwoofers featuring direct radiation.
Ergonomics allows all type of handling by only one person.
The compactness of the TB118S is suitable for the constraints of fixed
installation discreetness while the ease of handling will answer to the
constraints of touring companies.
The TB118S subwoofer is specially designed to offers great musical quality
optimised in the low frequency bandwidth.

(1) Frequency response is limited to 80 Hz by the
low-pass filter of APG processors, however the
TB118S can be used up to 140 Hz.
(2) The acceptable AES power handling corresponds
to a 2 hours test using pink weighted noise (peak
factor 6dB) through a frequency range.
(3)The 4 pins Speakon connectors are wired 1+,
1- in and 2+, 2- to allow flow of signal to the top
speakers.
(4) The KR100 & KR125 options are respectively
100mm and 125mm rotating casters with brakes.
(5) The tropicalization option includes the coating of
the cabinet with a polyester shell, stainless steel
screws and bolts and waterproofing treatment of the
membranes.
“A five years warranty covers passive
filters, transducers and compression
drivers. The warranty does not cover
cosmetic damages and damages due
to misuse, improper installation, or
damages caused by alterations.

APG has a comprehensive research and development policy for
the continual improvement of its products and service. Due to this
new materials, manufacturing methods and technological changes
may be introduced without prior notice. As a result, an APG
product can differ from its published description in certain areas.
However, unless otherwise indicated, its characteristics will always
equal or better the published specifications.
