The STL 400 A is a full range active bi-amplified loudspeaker that offers a 320W + 80W RMS output. Equipped with a 12” neodymium woofer, 1” horn and Class D switching amplifier (ICEpower® by Bang & Olufsen), it is ideal for both indoor and outdoor live music events featuring bands or DJs. The loudspeaker’s new processor-controlled TSSTM keeps the internal amplifier at maximum efficiency, guaranteeing both high sound pressure and audio fidelity. With SR’s Physiocon2TM processor, exceptional performance is assured at all frequencies and volume levels. At the same time, the unit itself remains extremely portable and light. For even greater output and bass response, one or more STW 600 subwoofers can be added. The STL 400 comes with a 40 mm-bored flange on the bottom suitable for a standard speaker floor stand.
