FEATURES
Passive subwoofer for extending the bass frequency response of all hd C- / M- / ML- /PL- Beam series column loudspeakers.

Thanks to its versatility and compact design, excellent dynamics, and dry bass reproduction, the hd Slim265 is ideal for a variety of environments such as restaurants, bars, airports, train stations, conference rooms, hotels, television studios, churches, A/V installations, and home theater. It is designed for use with Harmonic Design system amplifiers, ensuring precise low-frequency reproduction.
