No, Not a Speaker

You can be forgiven if this looks like one of those odd, transparent speaker systems. But it wasn't put in the Avalon room to compete with the Avalon Time. Its a passive room treatment device from Acustica Applicata (sounds like a singing technique, like a capella), an Italian company. The visible "eye" is a mechanical iris diaphragm, which combined with a port in the base with an adjustable opening and an internal membrane can tune the device to between 26Hz and 60Hz. This is said to improve the low frequency resolution by tuning out bass problem areas over a narrow or broad range. $3600 each.
