How Can We Help?
The high-performance woofer features a polymer-coated aluminum cone for high performance down to the 38 Hz and pure butyl rubber surround for long-life and high reliability along with extended-polepiece magnet design for long excursion and tight, low bass. The pure titanium dome high frequency driver is loaded with a built-in EOS (Elliptical Oblate Spheroidal) waveguide for low distortion and a smooth frequency response. A low-diffraction swivel-mounting system enables the user to direct high frequencies where required without the diffraction distortion inherent in other aimable tweeter designs. A high-slope crossover network maintains natural midrange sound and produces more even coverage throughout the listening area.
The Control 100 Series speakers are voiced similarly to other JBL Control Contractor models, allowing mixing with surface-mount and in-ceiling speakers within a single listening space. The premium sound quality makes these loudspeakers ideal for critical listening environments, yet they are high power and rugged enough to handle venues requiring high-SPL, heavy duty-cycle music.
The speaker fits into the wall space of ordinary stud-wall construction. An optional rough-in frame is available for installing the speakers into standard stud walls in new-construction projects. As is the case with all Control Contractor speakers, the baffles and grilles are paintable to match any decor.
Rear Air Cavity Considerations
The Control 126W is designed to function over a wide span of rear air cavity sizes within the wall. The optimum air cavity (sometimes called "loading volume") for fullest low-frequency performance is between 20 to 40 liters (0.7 to 1.4 cu ft). In a wall with studs located 16-inches on-center, this approximately equals a 23-inch to 46-inch high space. It is recommended that the air cavity behind the speaker be sealed by the use of silicone sealant or similar material to help create an air-tight seal and minimize wall noise.
Control 126W Features:
- 165 mm (6.5 in) polymer-coated aluminum-cone woofer with pure butyl rubber surround.
- 25 mm (1 in) pure-titanium dome low diffraction swivel aimable titanium tweeter.
- High-slope crossover for natural midrange sound.
- Extended bandwidth performance of 38 Hz - 20 kHz.
- 50 W continuous (100 W program, 200 W peak) power handling (126 W).
