What do you want to know? it is a small satellite designed by Roy Allison and manufactured in Mass. and then later in Kentucky after AA was bought out. Its first iteration used the famous unequaled ultrawide-dispersion Allison tweeter (driven halfway up the voicecoil) and a second iteration used a good OEM ~3/4" donut-type dome. It works best with either of the two Allison passive 8" subs, one a minicube dual-voicecoil 12" cube and the other a pushpull 2-woofer design, both of which really pop, as Roy used to say. They reach up a bit higher than many subs, which has zero audible or localization consequence no matter what you have heard or read, meaning to 125-150Hz, which is where the satellite rolls off.

As for the ESW, different poster, it is an equalizer consisting of steep reciprocal ~+12 gain settable for three different rolloff points of sealed (sealed only!) 8" - 12" woofers. Must be 'acoustic suspension.' Designed by Mark Davis for AA. Very handy and subtle with the right woofers. Extends the abovementioned subs dead flat to 20Hz.
