Subwoofer Greeley CO

North Reading, MA -- B&W Loudspeakers has introduced the ISW-4 as its new best-in-class, in-wall subwoofer.

The ISW-4 features dual B&W designed long-throw, eight-inch bass drivers utilizing Kevlar/paper cones. The combination allows the ISW-4 to produce substantial bass down to a very low 17 Hz (-6dB EQ at A setting on the SA-250.) Also, a braced BB-ISW-4 MDF backbox has been designed to prevent wall shake and cabinet distortions that plague other designs.

B&W also attributes ISW-4's high level of sound quality to the dedicated SA250 mono power amplifier/crossover. The SA250 is the ideal match to achieve the utmost performance from the ISW-4, with its 250 watts of power and an audiophile-grade electronic crossover built in.

The crossover is a fourth order Linkwitz-Riley with adjustable increments from 40Hz - 140Hz. Features also include a low-pass filter defeat, 0/180 degree phase switch, three-position bass extension switch, movie/music EQ switch, and an On/Auto-Standby switch. Amplifier inputs and outputs include XLR and RCA line in and link out. There is also a 3.5 mm jack for 12 V trigger on/standby, equalization, and movie/music. The cabinet is a 2U height (3.5 inches) for standard rack mounting.

The ISW-4 is finished in a semi-matt white suitable for custom painting. The grille is the same size as the CWM-8180 (cut-out dimensions 19.1 inches high x 10 inches wide.

A pre-mount kit is available for new construction, as well as the MDF back-box to optimize cabinet volume for the drivers and reduce acoustic bleed-through to other rooms. Use of the BB-ISW-4 backbox is strongly recommended.
