The H721 consists of a combination of hyperbolic / Tractrix horn flare coupled to a high power 21” ND driver. The back side of the driver is enclosed in a sealed box that helps reducing the excursion of the diaphragm and contributes to the overall output the system can achieve. This single 21 " renowned Horn design is an evolution of a highly appreciated loading technique developed back in 1992 by Delta Loudspeakers.

Developed to work with any mid high frequency speaker available from Lange Loudspeakers the H721 delivers a specific sound character oriented to electronic music and live concert venues. Compared to our H718 the H721 delivers consistently more liveliness below 45 Hz.
The H721 integrates a 1,5 meters long horn with a mouth area of 5310 cm2 allowing optimum coupling to the air. The cabinet delivers the maximum possible performance of the driver used conserving a remarkable compactness for a highly flexible application requiring less transport costs.

The high excursion yet high magnetic induction driver has been selected in order to obtain an optimal thermal performance under high power conditions. Special Voice Coil winding techniques as well as carefully selected adhesives also contribute to the high power this system can handle. Internal bracing give the cabinet the robustness needed for years of dependable service. Built with the highest quality 18mm Finnish Birch the cabinet is precisely assembled, glued and pressed together for maximum strength. Black spattered textured finish further improve the robustness of the cabinet during the day after day, year after year service.
