"The CS3 comes with a little black box that must be connected in-circuit at some point, preferably between the preamp and power amp (although the Tape Monitor loop will do), and then plugged into an AC outlet, preferably unswitched. The box contains active circuitry which, as with the ITC-1 system reviewed last month, boosts the system's low end to compensate for the fact that each speaker has only a 10" woofer. Located late in the system's circuitry, directly ahead of the power amp, the equalizer is likely to contribute far less sonic pollution than it would if it were located, say, between the cartridge and preamp. When bi-amping, it is used only with the woofer amp and thus cannot possibly affect the higher frequencies.

This bass-boosting approach has been tried many times in the past, but it never caught on until recently because 1) few woofers could take that much LF boost without distorting or bottoming, and 2) amplifiers capable of producing enough power to yield clean low end at such elevated power levels were few and expensive. Times—and components—have changed.

Low-end boosting actually offers two advantages over the use of a large bass-radiating area. The smaller the woofer area, the easier it is to locate the woofer where it excites the fewest booming-up room resonances; I believe this is one reason why the CS3 behaves as well as it does at the low end. The second advantage is that one 10" driver stores far less energy than one or two 12" drivers. Energy storage and re-release (later in time) is one of the major factors in low-end coloration, and one of the principal reasons some speakers are described as "fast" (low energy storage) and others "slow" (high energy storage)."
