Impressive Components for a Perfect Bass Speaker
Due to the high-quality transistor technology, the well-established design of these active subwoofer modules allows for an impressively warm sound of the self-built subwoofer system. Features and workmanship of these modules perfectly meet all requirements. SAM-1 and SAM-2 feature great dynamic reserves.
Active subwoofer module, 250 WMAX, 125 WRMS - High-power active module
- 24 dB subsonic filter
- Variable low-pass filter: 50-150 Hz (18 dB)
- Semiparametric bass boost (variable 30-50 Hz midrange with boost up to 6 dB, continuously adjustable)
- Continuously adjustable phase control 0-180° for uncompromising room correction and an optimum set-up of your speakers
- Variable high-pass filter: 50-150 Hz (12 dB) for equalizing the bass frequencies of the satellite amplifier and the satellite speakers
- Ground lift switch from the studio technology against hum interference
- Various protective circuits against short circuit, overheating and DC voltage overload
- Perfect drive for bass speakers with a diameter of up to 46 cm
- Impressive sound and workmanship
The high-quality active high-pass filter of the SAM-2 with versatile adjustments can conveniently be used as a bass relief of the main speakers and for optimising the sound. However, a regulated preamplifier output (Pre Out) is required for this. This kind of output is partly present at high-quality separable full amplifiers (Pre Out/Main In) or automatically provided by preamplifier/power amplifier combinations or when using mixers.

SPH-10M, MSH-115HQ, RBT-95SR and SAM-2 in the speaker building concept 2DOT1
"A system of appealing design which provides an equally nice sound ... the speaker building concept features an amazing adaptability and almost unlimited settings ... incredibly suitable for everyday use, is capable of reproducing any kind of music and suitable for home cinema systems. The system provided an absolutely amazing sound when tested in the audio room. The small speakers appeared to reproduce the complete bass range. There was no way of locating the subwoofer. The tactics with the tiles achieved great results ... nothing trembles, even though a powerful bass speaker of a high power capability is set-up in the room. The satellites provide an extra light and high-resolution sound."
