Slim. Elegant. Powerful. Complete.

An incredible detailed, full-range and non-fatiguing listening experience with an unbelievable deep and holographic soundstage. That is what Stilla is all about.

Designed to perfection by using all eight aspects of Aequo Audio's Octagon philosophy, the Stilla loudspeaker offers almost all audiophile characteristics of his big brother - the multi-award winning Ensis model - and with its slim and elegant design it is a true enrichment for every interior.

Stilla specified by

the Octagon Philosophy

Size and Form

A very slim and stylish floor standing speaker, designed by the credo: form follows function. Built by hand out of the finest and high-tech developed materials like Scandinavian plywood, hdf, high stiffness artificial stone and aerospace billet cnc aluminium.  Highly customisable to match with every interior, perfectly finished in every detail.

Soundstage & Imaging

A time-coherent tweeter with acoustic lens seamlessly integrated in the fully in phase midbass and subwoofer alignment. Thanks to absolute minimal diffraction by its slim size, curved sides and invisibly attached high density sheep wool behind the front hood, the speakers disappear completely, producing an incredible pinpoint wide and deep 3D soundstage.

Room acoustics

Easy speaker-individual low frequency adjustment (ARPEC™) will provide musical satisfaction  by enabling easy adjustment for both small and large rooms, as well as rich or lean recordings and is suitable to overcome imperfections caused by asymmetry of the room. Technology for the reduction of indirect ceiling, wall and floor sound (EHDL™) and a modest sized elliptical shape enclosure without large reflecting surfaces ensures high compatibility with all rooms.



Absence of bass reflex ports on the back or the side and a small footprint allow easy placement. Sounds right if placed near rear walls and even corners after easy low frequency adjustment with the ARPEC system where individual adjustments can be made corresponding to each speaker’s boundaries. 



Super-low distortion drivers with advanced materials and technology and the best in class N-core amplifiers, as well as a stiff highly advanced resonance-free artificial stone enclosure add no audible sound to the music. No more listening fatigue and more space for music. 


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 the latest design features 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 fast high precision features together with the ideally balanced stiffness and flexural damping in the moving midbass and tweeter membranes, delivers maximum enjoyable resolution at all frequencies. 

Amplifier Matching

Easy to drive for all amplifiers: hybrid active system with two 250W N-core powered 7 inch subwoofers that do all the heavy lifting, and an 8 ohms nominal impedance and high sensitivity on the passive side ensures easy companionship with your amp of choice. Furthermore the ideal ratio between open resolution and natural smoothness in the midbass and matching tweeter gets the best out of virtually any high quality amplifier.


The full analog signal path without digital to analogue or analog to digital conversion losses are ideal for those who like to keep (further) conversion out of their system (using pure analog sources like phono or high sample rate/DSD sources).



Stilla is equipped with high linear excursion drivers, including two 7 inch subwoofers, capable of clean sound at high levels with minimal compression and distortion. The motor’s magnetic system has been optimised using finite element analysis to create a large symmetrical force field. Coupled to an special paper cone coated for maximum pistonic behaviour, as well as an extreme linear suspension system, all ingredients are just right for unreal dynamics versus size, and an overall excellence in appropriate slam and depth at all listening levels.

WEIGHT  |  21 kg


ENCLOSURE  |  Floorstanding, Horn loaded bass reflex

FREQUENCY RANGE  |  14-35.000hz, *low frequency extension and gain is steplessly adjustable to match room size and acoustics.

IMPEDANCE  |  8 ohms nominal (for all amplifiers rated 2 to 8ohm)

TWEETER  |  The  Innovative high frequency transducer system is equipped with Aequo Audio's F40 high frequency transducer for high resolution and very low distortion. It's concentric fabric ring and dome design for extended frequency bandwidth, billet aluminum dispersion cone on carbon fiber rod to eliminate high frequency irregularities and fix the middle dome to eliminate membrane resonances. Enhanced Horizontal Dispersion Lens (EHDL™) ensures 3D holographic soundstage and imaging in all rooms.

MID BASS  |  High self-dampening mineral-filled polypropylene blend cone, low loss surround and suspension and well ventilated built to avoid large excursion compression. Hexacon voicecoil, Kapton-aluminium former. Powerful motor with very low distortion and super-fast Symmetry Drive (patented).

SUBWOOFER  |  Double 7 inch active powered, high linear excursion subwoofers opposed at 45 degree angles to cancel out all sideway vibrations. Nomex coated subwoofers with wide symmetric magnet field, large excursion, very low distortion. Active powered and controlled by innovative system with full analog signal path to easy adjust placement and room size and produce a natural deep roll off in the lowest frequencies.

CROSSOVER  |  Passive, balanced, in-phase crossover filter with only high-end capacitators and inductors. Unique filter topology without capacitators in line with the midbass for uncolored signal performance.
