The range of subwoofers includes a number of bass and subwoofer models of different sizes and power ratings that use two types of acoustic load developed by APG.
The concept of the interactive double chamber (bandpass) makes it possible to considerably reduce the load volumes of the loudspeakers, hence the impressive compactness of the loudspeakers concerned. K-Horn technology consists of adding a horn and a bandpass load. This exclusive technology provides an efficiency gain of between 4 and 6 dB SPL compared with a simple bass-reflex and direct radiation load.
The "iS" range consists of compact subwoofers ideally suited to medium-power systems for both performance and fixed installation.
The iS110 is an ultra-compact, portable subwoofer, ideal for fixed installation and small mobile kits.
The iS112 is a compact subwoofer designed for high-precision bass reinforcement.
The iS115 is an ultra-versatile, high-power subwoofer in a compact, lightweight format.
