Description
Each speaker has two woofers, one mid-woofer, one midrange, and one tweeter. For the speaker to reproduce the full spectrum of sound with the absolute highest quality, a combination of four different driver types has been carefully chosen.
The two 250 mm (11-inch) aluminium sandwich woofers have been designed together with Accuton engineers, especially for the Estelon flagship loudspeakers. These drivers have an extremely stiff and lightweight membrane and very long linear excursion. In combination with the Cell concept motor system, where the voice coil is almost the same diameter as the whole membrane, these drivers in the Forza cabinet can reproduce a truly deep, accurate, and effortless bass. The Forza’s bass has been said to sound like “live bass”. This is a result of meticulous engineering.
The 190 mm (8-inch) aluminium sandwich mid-woofer has also been co-developed together with the Accuton engineering team, with a unique motor system employing neodymium magnets to have higher sensitivity and suitable parameters for the Forza.
The 168 mm (7-inch) ceramic membrane midrange driver from Accuton employs a lightweight, extremely rigid, alpha-corundum membrane. In combination with the powerful, highly optimized Cell concept motor system, with a neodymium magnet ring, the result is a highly efficient and transparent sounding midrange driver.
The 25 mm (1-inch) chemical vapor-deposited diamond membrane tweeter from Accuton can reproduce sounds at the highest frequencies, up to 60 kHz, with no distortions in the human hearing range.
Symmetrical driver positioning – both woofers have exactly the same acoustic load outside the loudspeaker as inside. Due to such configuration, both woofers move identically and without competing with each other. We call this Symmetric Driver Loading (SDL) technology.
The three upper drivers are positioned on the curved front panel in a way that from the listening position these are approximately at the same distance from the listener. This, combined with the meticulously fine-tuned cross-over filters, means that the sound from each driver reaches the listening position at the same time, resulting in a coherent, precise sound signal with uncompressed dynamics, perfect tonal balance, very precise imaging, and lifelike sound-staging.
