Estelon Forza Ultra Loudspeakers
ESTELON FORZA ULTRA FOUR-WAY LOUDSPEAKER INTRODUCED
Estonian HiFi brand Estelon has introduced the Estelon Forza Ultra, a new four-way passive loudspeaker described as the next development of its Forza model.
The design of the Estelon Forza Ultra Loudspeaker incorporates new Accuton drivers, a redesigned crossover, Estelon’s proprietary connector system and Stillpoints Ultra SS V2 isolation as standard.

According to Estelon, development of the Forza Ultra focused on retaining the scale and overall character of the original Forza while making changes to transparency, dynamics and bass control.
ESTELON FORZA ULTRA DRIVER ARRAY
The Forza Ultra uses two custom 250 mm long-stroke aluminium dome woofers, manufactured by Accuton to Estelon’s specifications. The woofers use neodymium motor systems and Estelon’s Symmetric Driver Loading technology, which provides the two drivers with the same acoustic loading.
A 190 mm midwoofer and 90 mm midrange driver also use Accuton’s Crystalid membrane technology. The company says the combination of high rigidity and low moving mass is intended to support transient response and low distortion through the mid frequencies.
At the top of the range is a 25 mm next-generation Accuton diamond tweeter, featuring an updated surround and multi-cavity rear chamber. Estelon specifies high-frequency extension to 60 kHz, with the response linear to 33 kHz.
REDESIGNED CROSSOVER AND SIGNAL PATH
The new drivers are integrated using a redesigned crossover network, with the circuits tuned for phase integration, time alignment and tonal balance. The crossover sections are housed in acoustically isolated chambers.
Estelon’s Flat Foil Direct Coupling connects the crossover components in a star configuration, with short cable runs. Components are hand-soldered onto a dedicated mounting plate rather than using conventional PCB materials in the signal path.
The Forza Ultra also introduces Estelon’s spring-loaded connector system, originally developed for the Extreme Mk II. A copper foil ribbon runs directly towards the crossover, and the terminals accept banana plugs, spade connectors and bare wire. Bi-wiring is supported.
ESTELON FORZA ULTRA CABINET AND ISOLATION
Stillpoints Ultra SS V2 isolators are supplied as standard. The loudspeaker cabinet weighs 150 kg per speaker, and the isolation system uses ceramic bearings designed to dissipate vibrational energy and reduce the transfer of micro-vibrations between the cabinet and floor.
The cabinet is made from Estelon’s proprietary marble-based composite and uses non-parallel internal surfaces and dedicated driver chambers. The curved exterior is intended to reduce diffraction, while the front-panel geometry positions the upper drivers to control high-frequency dispersion.
The Forza Ultra retains Estelon’s sculpted cabinet approach, with a new protective grille for the midrange driver. New two-tone finishes combine a Deep Dark Grey base with selected high-gloss colours. Bespoke colours remain available on request.
SPECIFICATIONS
The sealed enclosure has a specified frequency response of 27 Hz to 60,000 Hz, with a 400 W power rating, nominal impedance of 3 ohms and minimum impedance of 2.3 ohms at 51 Hz. Sensitivity is rated at 89 dB at 2.83 V, with a minimum recommended amplifier power of 20 W.
Crossover points are 90 Hz, 800 Hz and 2.5 kHz. Internal cabling is by Kubala-Sosna. Each loudspeaker measures 1,675 x 617 x 682 mm and weighs 150 kg. Estelon recommends rooms between 40 and 125 m².
ESTELON FORZA ULTRA PRICE AND AVAILABILITY
The global launch programme begins in October 2026. More Music will introduce the Forza Ultra in the Benelux, including demonstrations at Dutch Audio Event on 10th –11th October and l’Audiophile Luxembourg Show on 23rd – 25th October.
Nautilus will present the speaker at the Audio Video Show in Warsaw from 23rd – 25th October, with launches also planned through partners in Turkey, the United States and China.
The Estelon Forza Ultra has an MSRP from €159,000 / US$227,000 per pair.
HiFi PiG says: We are very excited about hearing the new Estelon Forza Ultra at the upcoming Dutch Audio Event 2026, in Eindhoven!
