The correct model is the ZETA, which is QUINTESSENCE ACOUSTICS best speaker (above the Stealth ). It features a dedicated ,1000 Watts per channel DSP controlled amplifier that drives the 2 twelve inch woofers. The upper section is passive and it’s frequency response is from 40 to 35k. Speaker efficiency is 90 dB. This speaker is extremely dynamic, and throws a very wide and deep, three dimensional image. Very smooth, with a some what warmer tonality versus what passes for a lot of Uber high end speakers today (overly detailed and analytic). May consider possible trades plus cash for a lesser component.
