Perhaps my focus on the "problem" in the CS2, now essentially cured, led me to pay inadequate attention to the high-frequency behavior of this tweeter. Its response is essentially flat out to 35kHz (according to information from Thiel), and sounds that way. The upper harmonics of triangle and cymbals are preserved with excellent detail. If I…

Fig.1 shows the plots of impedance with frequency for the Thiel loudspeaker. It agrees with the appropriate specified impedances in the review heading, and obvious features can be distinguished, such as the box resonance for the CS3.5 at 33Hz. I would conjecture, however, that Jim Thiel has used some form of conjugate load system in his crossover designs to give such flat curves with frequency. (This is where elements are added to the crossover to compensate for phase and impedance changes to result in a simple resistive load.) I would suggest, therefore, that like…

At least two companies, Westone and Sensaphonics, make custom earmolds that fit Shure headphones. Shure works closely with Sensaphonics, whom they recommend on their website and in their product literature, but I went with Westone because that's the company my audiologist usually works with.
The audiologist stuck a piece of cloth in my ear to protect the eardrum, then injected foam in the ear canals. During the two minutes the foam takes to harden, Westone recommends you keep your mouth open for best results. When my audiologist asked why,…
