Unless you live under a rock, you've followed Russia's invasion of Ukraine. You know something about sanctions against Russia and Russia's responses to those sanctions. If, in addition to not living under a rock, you're a tube-audio aficionado or electric guitar nut, you may have thought about a likely consequence of that war that's far less momentous than the destruction and carnage we see on TV: Will I be able to get new tubes for my amplifier?

The idea of a loudspeaker system whose frequency response could be tailored to suit room acoustics and/or personal taste is one that has always appealed to the high-fidelity perfectionist. Ideally, such a loudspeaker would allow you to raise or lower the level of any part of the audio spectrum to correct for, say, a sharp 370Hz room resonance or a mild absorptive condition that weakens, say, the 800Hz–3kHz range. Obviously, though, this kind of flexibility would require an infinite number of bandpass networks, each with its own volume control—which is an obvious impracticality.
