Where to buy?

The SX408A is an active powerful tandem ported 100W subwoofer with a special constructed 8" driver that is capable of producing an incredibly powerful and clear bass sound. It’s frequency response is as low as 37 Hz at -10 dB, and the frequency characteristic is very flat from 37 Hz to 120 Hz. This way, the sound coming from this piece of equipment is absolutely magnificent. It contains an integrated class H amplifier, which ensures a high efficiency level with very low distortion. This amplifier delivers an output power of 100 Watt to the subwoofer. Besides this, it also contains an active crossover network with a frequency of 120 Hz, and two output channels for powering satellite loudspeakers. The two amplified satellite outputs deliver a maximum power of 2 x 100 Watt at 8 Ohm or 2 x 160 Watt at 4 Ohm. The minimum load is 4 Ohm. For protection reasons, a built-in limiter is provided to limit the input signal when necessary. This limiter consists of three separate stages, one for every channel. This ensures the best sound quality with the least distortion for optimal performance. Power, Signal and Clip LEDs monitor the proper working of the integrated amplifier. Besides the high efficiency of the class H amplifier, the SX408A also contains an automatic power on/off circuit to ensure the highest energy-efficiency. The volume of the Sub and satellite channels is individually controllable at the back of the subwoofer with two potentiometers, and the general volume can be controlled by an external volume control or wall panel, by connecting it to the built-in RJ45 connector. This all makes the SX408A a simple but complete solution for a wide variation of fixed audio installations. The balanced input connections are just as the satellite speaker output connections made with euro block terminal connectors. There is the possibility to connect two satellite speakers with an impedance of 8 Ohm on each channel.
