Download the free iWoofer app to experiment with phase control, crossover settings, and other tweaks, or download the iOS iWoofer Pro App (iOS only) to get uber tweaky with automatic room correction to maximize the subwoofer’s performance. The Nero DualX8DSP powered subwoofer incorporates advanced digital amplifier technology that maximizes performance but generates very little heat. In standby mode, this powerful dual-woofer sub consumes less than 0.5 Watts, and when auto signal sensing is selected will automatically switch to a power saving stand-by mode. A great addition to any home theater system, rear-mounted controls allow you to dial in just the right amount of bass, and crossover control allows you to adjust the subwoofer’s frequency outputs while a phase switch lets you set the phase of the woofer from 0-180°. Our Nero Dual X8 also includes gold-plated inputs for the highest quality sound transfer and maximum sonic purity.
