We refoam in a different way, preserving original performance
Dust caps (the dome in the center of the speaker) on vintage Infinity speakers are an integral part of the original design, and determine frequency response in the woofers upper operating range. The usual refoaming process requires cutting out the dome to gain access to the coil, such that it may be centered in the magnetic gap with shims during the refoaming process. This destroys the original dome requiring replacement with a new and different one, as original domes are not available. The only way to retain original performance is to leave the original dome and its attachment to the cone intact. We do this by centering the coil in the magnetic gap electronically with test tones. The dome and its attachment are left completely intact and as original, thusly retaining the speakers original frequency response and overall performance, such that it will sound the same as when new.
