## About

Estelon's flagship and the shape the whole brand is built around: a four-way in crushed-marble composite whose central column telescopes, so the speaker stands anywhere between 1770 and 2070 mm and the drivers can be raised to the listener's ear rather than the other way round. Every transducer is Accuton, three of them custom: two 250 mm CELL aluminium-sandwich woofers, a third of the same running as mid-bass, a 168 mm ceramic midrange and a CELL diamond tweeter, vented through a damped reflex tunnel along the back. 250 kg each, 3 ohms nominal and down to 2.0 at 95 Hz, which is a load that wants a serious amplifier despite the 91 dB and the modest 20 W minimum Estelon quotes. The frequency response recorded here is the 33 kHz Estelon calls linear; the headline number on their page is 60 kHz. The drawn width follows the press render, which shows the column near full extension, rather than the 690 mm the base actually spans. $340,400 a pair.
