Forza Ultra

The second generation of the Forza, and the odd one out in the range: four ways, all of them dome drivers rather than cones, and a sealed enclosure where the rest of the flagship line vents. The 190 mm mid-bass and 90 mm midrange are Accuton Crystalid domes made for this speaker; the tweeter is Accuton's next-generation diamond, crossed at 2.5 kHz with the other points at 90 and 800 Hz. Isolation is by Stillpoints Ultra SS V2 rather than spikes. 27 Hz sealed out of 150 kg of marble composite, 3 ohms nominal with a 2.3 ohm minimum at 51 Hz. The response here is the 33 kHz Estelon calls linear, not the 60 kHz headline. From $227,000 a pair.
