As the winter has turned colder, my mind has turned loudspeakers and am in the middle of a nice sized project. Although I find loudspeakers just as creative and involving as my other hobbies, for some reason, I have a hard time sharing thoughts on the subject. Maybe, driver compliance, diffraction, and psychoacoutics feel so involved that I am unable to explain them. Whatever the reason, the project is to build a pair of desktop speakers and amplifier with active crossovers in a hybrid omni-directional design. If you look close at the driver in the picture, you will see that the dust cap has been cut off. I'm in the process of adding mass to the coil former to lower the resonant frequency, along with other tweaks to get the performance where I want it. The monitor shows the measured frequency response of a woofer.

I guess the point of this post is to say that I haven't fallen off the face of the earth and to wish all a Merry Christmas.
