Hoping for a change in speaker tech.

Here is a small statement from the pro side of speakers that would be a nice add to the consumer/home market.

RCF has developed what it calls “Impedance Control Coil” technology for midrange transducers, including those found in the TT + line array series. A secondary coil wound on the speaker yoke and driven in opposite phase to the primary coil effectively cancels the primary coil inductance, increasing sensitivity and reducing distortion. A primary effect is the improvement of the temporal behavior of the transducer, upgrading the crossover transition from the midrange to the compression drivers.

I think this would be a nice improvement in the home market and in the use of near field monitors.

Among the many aspects of loudspeaker design, JBL Professional remains consistently focused on refining and upgrading drivers, as evidenced by Differential Drive. Instead of using a single voice coil in a single magnetic gap, it makes use of a pair of in-line voice coils in separate magnetic gaps, resulting in a lighter, more efficient design that also offers improved removal of heat from the motor structure.

A recent culmination of this focus is the D2 dual-diaphragm, dual-voice-coil driver found in the VTX Series V25 line array, which provides higher power handling with lower distortion, coupled with extended HF reproduction and a smoother response. These benefits in performance are attained from a unit that’s the same footprint as traditional drivers, and at a weight reduction.

I think this would be a help in the Sub Woofer world also, along with the opposite coil tech from RCF to reduce problems.

If we have a good discussion and others and companies see this as useful they might provide to the consumer on some of the top end speakers. Leading to a mid price speaker with nice features and we will all find better sound.
