The Yorkville Elite Series 21" 2400W Powered Subwoofer is a high-output, rear horn–loaded sub for clubs, concert venues, bars, and theater applications. The ES21P is designed to add powerful bass to any setup including the Yorkville Elite Series full-range cabinets. With a built-in power amplifier and 2400W of program power, this 21" subwoofer produces a frequency response of 32 to 150 Hz and a maximum peak SPL of 142 dB.

The rear panel offers an XLR mono blended input, as well as standard XLR and 1/4" inputs and outputs, which allow for flexibility when working with multiple subwoofers. A dedicated input mode switch allows the ES21P to accept line- or speaker-level sources. The rear panel also features a master level control, a high-frequency rolloff control from 80 to 150 Hz, and three DSP presets that change tone and loudness. Additionally, the ES21P can be controlled wirelessly via Bluetooth with the free Yorkville control app available for iOS and Android platforms. The 11-ply Russian birch enclosure is coated with heavy-duty black Ultrathane paint and protected by a perforated metal grille. Integrated wheels and carry handles simplify transport, while the integrated pole cup accepts standard speaker poles for easy full-range speaker deployment.
