Estelon Forza Reference Speaker

The Estelon Forza Reference Speaker is a four-way floor standing loudspeaker engineered for music enthusiasts seeking acoustic accuracy, expansive soundstaging, and effortless dynamic scale. Standing nearly 1.7 metres tall, each cabinet integrates high-grade driver technologies into an acoustically optimised, single-piece enclosure designed to reproduce the full audible spectrum with minimal distortion.

Precision Accuton Driver Array:

High-frequency playback is anchored by an Accuton 25 mm inverted diamond dome tweeter capable of linear response up to 60 kHz without fatigue or harshness. Directly below, a 168 mm ceramic midrange driver delivers natural, transparent vocal performance, complemented by a 190 mm aluminum sandwich mid-woofer that creates a seamless acoustic bridge between the midband and lower octaves.

Symmetric Driver Loading for Fast, Articulate Bass:

Low-end energy is powered by two 250 mm aluminum sandwich woofers positioned symmetrically on the lower flanks of the cabinet. By balancing internal and external air pressure identically across both drivers, this configuration reduces mechanical strain and prevents driver interference, producing articulate, room-filling bass that sounds authentic and controlled at all volume levels.

Time-Aligned, Resonance-Free Enclosure:

The loudspeaker is cast from an ultra-dense, marble-based composite material that eliminates internal standing waves and cabinet resonance. The gently curved front baffle maintains an equal distance between the upper drivers and the listening position, delivering precise time alignment so that every musical transient reaches your ears in coherent harmony.
