Special Features

• Models

I.Q has produced two different models, the normal 200T and the newer 200T SSC (String Suspension Concept). The SSC models used a specially designed tweeter, as well as the three crossovers and the tweeter attached to tensioned ribbons decoupled.

• Inductive coupling

The front-mounted woofers, driven by the amplifier, generate a signal via a second voice coil that is intended to control the passive, rear-mounted woofers, which are coupled via a common volume.
