Active Audio TB218S Subwoofer
High technology for professionals and music lovers
The APG TB218S is a low frequency subwoofer designed to complement high power sound systems.
It is equipped with two Neodymium 18" cone speakers, mounted in a new generation dual interactive K-Horn™ chamber. This specific arrangement allows reducing load volume and creating a horn effect that increase efficiency by 4 dB and allows controlling cone excursion. The TB218S boasts a very high product, making it one of the most efficient on the market. Extensive study of ergonomics has been conducted to ensure the highest level of comfort in handling, transportation and storage. The optional KR100 and KR125 offers the possibility to the TB218S to receive four large rotating casters, allowing “convoy” style haulage, or “wheelbarrow” style handling.
A total of eight handles for all types of manipulation associated to its limited weight (163 lb) makes it easy to handle in any environment. Optimization of the shapes and internal bracings has allowed 20% weight reduction whilst offering increased rigidity. The TB218S must be used with an APG digital processor DMS48F. The TB218S is ideally used for low frequency reinforcement.
