In order to provide greater flexibility and cater to listener's preferences, Induction Dynamics® includes a unique switch on the ID1 and ID1.15. This toggle switches the lower crossover in and out, allowing users to operate their speakers as either a 3-way plus subwoofer (home theater) or as a 4-way (stereo).

To listen to these speakers in stereo mode, powered by a single stereo amplifier, place the switch in the 4-way position. In this mode, a passive crossover between the subwoofers and the other drivers will be switched into the circuit, meaning all of the drivers in each speaker are powered by one signal from each channel of a single stereo amp.

For home theater applications, flip the switch to the 3-way plus subwoofer position. In this configuration, each channel powers the 3-way portion of your speakers (tweeter, mid-range, and woofer) while the subwoofers are powered separately by the A2 subwoofer amplifier. The home theater 3-way + option allows the speakers to serve in a modern audio/video surround sound system with extended bass control and response capability.

The Choice is Yours
The 3-way +/ 4-way switch comes standard on the ID1 and ID1.15 and is built to military-grade specifications with cadmium-plated contacts.
