WHARFEDALE SIGMA 18B



18-inch Passive Subwoofer



(1Pc)



Overview

SPECIFICALLY ENGINEERED FOR FIXED INDOOR INSTALLATIONS

With its discreet and unobtrusive design SIGMA-18B features the latest proprietary Wharfedale Pro driver technology. In addition, SIGMA-18B uses a newly developed angled corner port system so that the overall sound quality is compromised. Available in black or white SIGMA-18B and the new SIGMA SERIES are already a versatile and favorite choice for installers.

DOUBLE ROLL SURROUND & DRIVER TECHNOLOGY

SIGMA 18B uses the latest in Pro Tools technology: Engineers have incorporated a curvilinear, double-roll surround for stability and power. Combined with a 2.5 "voice coil for improved thermal dissipation, users can expect consistent performance at all times.

ACOUSTICALLY MATCHED CABINET

Wharfedale Pro engineers have matched the acoustic properties of the cabinet to the proprietary driver technology within, while taking physical aspects into consideration for optimal positioning and size for installation. By using a newly developed angled-corner port system, the cabinet height and overall size have been reduced - ideal for unobtrusive positioning within your venue. The angle-corner port system is also fine-tuned acoustically to ensure low-end punch - just as you would expect with a larger PA speaker. SIGMA 18B is also coated with the latest generation chip-resistant, Rhino Rock paint.

FINE-TUNED CROSSOVER

The crossovers ensure perfect integration between the drive units and the cabinet. Electronic components are carefully selected, while over-complex networks have been avoided to maintain a pure and strong audio signal. SIGMA 18B also features an NL4 (speakon compatible) High Pass Output connector allowing for direct connection to another SIGMA series.
