The Ensis loudspeaker fully embodies the Octagon philosophy. It is the product of over five years and many thousands of hours of research and design by the Aequo Audio engineering team. The result delivers qualities in high-end sound reproduction to satisfy even the most critical listeners. But most of all, it ensures long hours of listening pleasure, enchanting you with the music you like best. Any music.
Demonstrations of its capabilities have astounded high-end enthusiasts by its virtually unlimited low frequency response, soundstage, imaging, dynamics, precision, cleanliness, in any room and with a wide range of amplifiers.
The Ensis specified by
the Octagon Philosophy
Size and Form
A unique and modest size floor standing speaker built by hand out of the finest and most advanced materials. A piece of art that can be highly customized. Beautifully finished in every detail.
Soundstage & Imaging
A time-coherent tweeter with acoustic lens seamlessly integrated in the fully in-phase midbass and subwoofer alignment. Together with a small and low diffraction enclosure they provide incredibly realistic reproduction of the original recording, including a full 3D soundstage and precise imaging over a wider sweet spot.
Room Acoustics
Easy speaker-individual low frequency adjustment works well with both small and large rooms, as well as rich or lean recordings. Technology for the reduction of indirect ceiling, wall and floor sound, and a modest sized elliptical shape enclosure without large reflecting surfaces ensures high compatibility with all rooms.
Placement
Absence of bass reflex ports and a small footprint allow easy placement. Sounds right if placed near rear walls (no dipole) and even corners after easy low frequency adjustment.
Cleanliness
Ultra-low distortion drivers with advanced materials and technology and the best in class N-core amplifier, as well as a stiff highly advanced resonance-free enclosure add no audible sound to the music. No more listening fatigue.
Precision
All drivers are built to excel in extended clean low frequency bandwidth. Hence smaller and faster drivers are responsible for a larger part of the frequency spectrum. In addition, motors of all drivers have a low induction, low eddy-current symmetric design for super-fast signal response. A low order crossover filter and closed type enclosures for all drivers, ensure minimal group delay in the crossover band. The fusion of these high precicion features together with the ideally balanced stiffness and flexural damping in the midbass cone material, delivers maximum enjoyable resolution.
Amplifier Matching
Easy to drive for all amplifiers: hybrid active system with 500W N-core powered subwoofer, 8 ohms nominal impedance and high sensitivity on the passive side. Your amplifier is relieved from subwoofer duty. Ideal ratio between resolution and damping in the midbass and matching tweeter is sound-compatible with virtually all amplifiers.
The full analog signal path without digital to analog or analog to digital conversion losses are ideal for those who like to keep conversion out of their system (using pure analog sources like phono and analog and pre-amplifiers or high sample rate/DSD sources).
Dynamics
The Ensis is equipped with high linear excursion drivers, including a 10 inch subwoofer, capable of clean sound at high levels with minimal compression and distortion. Extra heavy duty driver motors and advanced materials provide unreal dynamic capabilities, and excel in pure natural sound at low listening levels.
