Subwoofers TB118S Low frequency Subwoofer One Neodymium 18” with 4” ventilated voice coil. Double Interactive chamber with K-Horn™. Features High efficiency and high power Exceptional SPL Max & dynamic capacity Compactness & handiness Low thermal compression and distorsion Applications Low and Infra low sound reinforcement High power & high precision Versatile application FOH/Monitor Specifications 35Hz – 250Hz 1150W AES 102 dB SPL @ 1W / 1m 138 dB SPLMax @ 1W / 1m 8 Ohm 32” x 24” x 21” (810 x 600 x 530 mm) Single channel amplification Processor mandatory 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.

(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.

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.
