The VR-30 is available in two models: one without the Foundation amplifier, which is entirely passive, and another that includes the amplifier. The amplified version provides 700 watts to the woofers, but all drivers operate through an utterly passive network. As mentioned, the amplifier features an isolation transformer with room gain control, but No DSP is used. The gain control allows for precise adjustment, providing flexibility in room placement and making achieving optimal in-room bass response more straightforward.
As previously mentioned, the amplifier features an isolation transformer with room gain control using NO DSP, which allows for easy adjustments, flexibility in room placement, and simplified achievement of optimal bass response. Additionally, the power amplifier for the three Accuton woofers offers more headroom and somewhat greater flexibility than the main amplifier.
