Convincing components for the best bass The tried and tested construction of these subwoofer active modules ensures a convincingly warm sound of the self-built subwoofer box thanks to the high-quality transistor technology. Equipment and the processing of the modules leaves nothing to be desired. SAM-1 and SAM-2 have large dynamic reserves.Subwoofer active module, 250 WMAX, 125WRMS
• High-performance active device
• Subsonic filter 24 dB
• Variable low-pass 50-150 Hz (18dB)
• Semiparametric bass boost (variable 30-50 Hz center frequency with infinitely variable boost up to 6 dB)
• Infinitely adjustable phase slider 0-180 ° for uncompromising room and installation adjustment
• Variable highpass 50-150 (12 dB) for the bass relief of the satellite amplifier and the satellite speakers
• Ground-lift switch from the studio technology against hum interference

Various protection circuits against short circuit, overheating and DC
• Perfect drive for bass Up to 46 cm in diameter
• Convincing sound and processing The high-quality, active high-pass filter of the SAM-2 with its adjustment possibilities can be comfortably used for bass relief of the main loudspeakers and for sound optimization. A prerequisite for this is, however, a controlled preamplifier output (pre-out) in the system as described, for example, (Pre-out / main-in) or as it is automatically obtained with pre-end stage combinations or the use of mixing consoles.Klang + Ton 02/2013 SPH-10M, MSH-115HQ, RBT-95SR and SAM- 2 in the kit 2DOT1 A very nice looking system that plays just as nicely ... the adaptability of the kit is incredible and the setting possibilities almost endless ... incredibly everyday, comes with every kind of music and is home-grown. In our listening room, we were astonished when we put the system to the test. The small speakers looked as though they would reproduce the whole low frequency portion. The subwoofer was simply not to locate. The tactics with the tiles go full ... it does not wobble, although a powerful, powerful bass is in the room. The satellites, on the other hand, play with a proper portion of air and fine resolution. "
