The speaker has a 380mm woofer with a front‑mounted waveguide that delivers bass up to 36 Hz (-6 dB), and an optimized compression tweeter with a horn completes the picture. All of this is powered by a Class D amplifier from Texas Instruments and a 32‑bit DSP. As a result, the speaker develops a power of 440 watts (RMS) and is capable of reaching a sound pressure of 132 dB.
