Estelon has unveiled the Forza Ultra, a second-generation successor to its flagship Forza loudspeaker that the Estonian manufacturer describes as sculptural art built around next-generation Accuton driver technology. Where the original Forza established Estelon’s curved, marble-composite design language, the Estelon Forza Ultra pushes the engineering further with an all-new four-way driver system and a completely reworked crossover network.
Every millimetre of the Forza Ultra is deliberate: driver position, cabinet curve and internal bracing are all shaped to interact with the room it stands in, so the surrounding space becomes part of the loudspeaker system rather than something the design merely tolerates. As with the rest of Estelon’s flagship range, pricing is available only through the brand’s local dealers.
A Four-Way Driver System Co-Developed with Accuton
At the heart of the Estelon Forza Ultra is a four-way passive design in a sealed enclosure, built around custom aluminium dome woofers plus a Crystalid midwoofer and Crystalid midrange, both co-developed with Accuton specifically for this cabinet. Accuton’s newest-generation diamond tweeter tops the array, extending resolution to a linear frequency response of up to 33,000Hz and a full frequency response of 27Hz to 60,000Hz.
The crossover network is engineered as an acoustic component in its own right rather than a simple frequency divider, with points set at 90Hz, 800Hz and 2.5kHz and each network tuned through measurement and critical listening for precise time alignment.
A Sculptural, Marble-Composite Cabinet
The Forza Ultra’s cabinet is moulded from Estelon’s proprietary marble-based composite, a dense material developed specifically for the complex, parallel-wall-free forms that define the brand’s loudspeakers. At 1,675mm tall and 150kg per cabinet, each speaker sits on Stillpoints Ultra SS V2 isolators, whose ceramic bearing system mechanically decouples the enclosure from the floor to lower the noise floor and sharpen bass transients.
A custom connector system inspired by the action of a piano key, and internal cabling from Kubala Sosna, complete a signal path Estelon treats as an extension of the acoustic design rather than an afterthought.
Bespoke, Hand-Finished Colourways
The Estelon Forza Ultra introduces a two-tone finish concept, pairing a deep grey base with a bespoke colour across four standard combinations: Silver Eclipse, Desert Pearl, Petra Gold and Ocean Spectra, with fully personalised finishes available on request. Each cabinet is finished by hand over several weeks, with multiple layers of paint wet-sanded and polished between coats.
For an equally meticulous but more compact alternative in Estelon’s own range, the brand’s original Forza loudspeakers remain in the lineup as a reference point for the design language the Ultra builds on. Full technical details and dealer contacts are listed via estelon.com. Estelon frames the Forza Ultra’s mission simply: extraordinary purity, precision and lifelike presence, so that the loudspeaker itself disappears and only the performance remains.
