Beetle - the airflow technology addresses any and all airflow situations. A high-impact situation is port flow; in a sense that is low hanging fruit. There are many other situations that apply to all speakers. I am looking at back-wave implications for the passive radiator and all drivers. Bass frequencies move more air, but all frequencies have potential. The flair around driver circumferences may come into play, especially at coupling frequencies where the driver transitions from constant velocity to constant acceleration. Air viscosity and turbulence are prevalent in such transitions. We're looking at the rim between the tweeter and coax mid in my newly acquired MCS1, which shares the 2.3 coax, similar to the 2.4. The 1.6 has a significant tweeter wave guide in conjunction with an acoustic loading device to suppress the oil-can resonance peak. Hmmm, what if that interplay might be settled.
Short answer is yes, many potential applications. The only audio implementation to date is a round port in a Tannoy monitor and augmentation of a B&W golfball textured port. My first application is the 1.6 slot to see what we learn in the higher resolution Thiel CS platform. By the way, the 2002 CS1.6 is better than I thought possible at $2K retail.
