STL 250A

The STL 250 A is a full range active bi-amplified loudspeaker that offers a 200W + 50W RMS output. Equipped with a 10” neodymium woofer, 1” horn and Class D switching amplifier (ICEpower® by Bang & Olufsen), it is ideal for live music applications in medium size locations and for sound coverage in venues such as piano bars, restaurants and clubs. 
STL 250’s design also allows it to be used as both PA loudspeaker and stage monitor. The integration of SR’s Physiocon2TM processor gives the loudspeaker an exceptional frequency response and enables it to project high output levels across the full frequency spectrum; a rear switch "monitor / live" set the processor Physiocon2 on monitor or live mode.
For even greater output and bass response, one or more STW 250 subwoofers can be added. The STL 250 comes with a 40 mm-bored flange on the bottom suitable for a standard speaker floor stand.
