The Extender

About the The Extender

The van den Hul The Extender is a unique compact device designed to restore the 'lost' live experience in sound reproduction by emitting a specialized signal that directly interacts with the brain, bypassing limitations of loudspeakers, room acoustics, and even ear defects. Placed on top of speakers facing the listener with a 90-degree signal opening angle, it enhances natural space, depth, high definition, and easy listening, making users feel physically present at the performance. It connects via a supplied cable to loudspeaker binding posts, requires an 18V DC power supply, and features a 4-position dipswitch for sensitivity adjustment (default position 3 for average setups; set one higher than expected levels). Not a super-tweeter, it produces no measurable or audible sound. Housed in a solid wood frame with front power indicator and company name, rear includes signal input, Wave On switch, power switch, and DC input. Sold as a pair.
