Genelec 1238 APM - active studio monitor, 3-way, tri-amplified, incorporating a 15" low-frequency driver with a power of 500 W, a midrange driver made in Finland with a power of 250 W, and a 1" metal dome high-frequency tweeter with a power of 200 W and DCW (Directivity Control Waveguide) technology. It offers a frequency response of 30 to 22,000 Hz (-6 dB). Amplification is provided by the removable RAM-L amplifier, which can be mounted in a 3U rack system, combining Class D amplification for mid and low frequencies with Class AB amplification for high frequencies. It features automatic configuration and calibration, as well as Genelec Loudspeaker Manager Control Network technology that allows for the creation of stereo and surround systems. The monitor can be oriented horizontally or vertically by rotating the mid and high-frequency driver panel by 90°.
