Apertura Audio SENSA
Our wish, when developing SENSA & SWING was to create small-size speakers that could fit in any limited interiors.
The new shape we developed combines an original design, simple and elegant while maintaining an optimal load volume.
SENSA is ARMONIA’s Worthy descendant. They share the same main features and concern for perfection inherent to the Apertura brand.
DRIVE UNITS
- A 16cm mid/woofer with an « isotactic matrix », cone like in Armonia, Edena and their big sisters. This material made of woven polypropylene strips, combines stiffness, lightness and good damping properties.
- The long moving coil allows a long linear excursion. Which is quite amazing for a speaker of this size.
- This drive unit comes also with an original suspension, featuring radial stiffeners that lower the interferences.
- High frequencies are reproduced by a tweeter, member of the famous “Ring Radiator” family.
- In addition to its unusual profile, it has a bullet shape waveguide and a rear damping chamber. The result is an extended frequency response, both at the top end (to above 40kHz), and at the bottom end to allow easier coupling with the bass/mid range drive unit.
CROSSOVER
- Proprietary « DRIM » structure with a triple attenuation slopes
- This technology cancels intermodulation on each sections of the crossover, which result in unsurpassed Clarity and finesse
- Each set of drive units (tweeter and mid/woofer) are individually measured and crossover values adjusted according to these sets measurements.
Hand wiring on a 140 µm copper printed circuit board. - Optimized crossover structure to avoid magnetic interference between components
ENCLOSURE
- The main goal, in this new cabinet design, was to limit vibration propagation on the most critical panels (especially on the back panel).
- High thickness panels (18mm)
- Internal multi-cavity framework with 3 bracing panels to stiffen the structure and create very specific areas where damping materials can be applied
- Bass reflex loading with an optimized double resonator. This specific configuration allows deeper low frequencies reproduction.
- Importance is given to damping treatment to cancel any standing waves. We are using 2 different types of dumping materials.
- 3 differents standard finishes available :
- Satin : light oak, american walnut
- High Gloss : white, piano black

Apertura's Sensa pairs compact floorstanding proportions with a remarkably coherent sound—delivering dense yet integrated detail density, continuous tonality and surprising bass extension to ~40Hz. Reviewer Srajan Ebaen praised its warm, burnished midband and imaging, noting the hand-wired DRIM crossover and refined treble that keep presentations cohesive and musical.
Pros
- Dense, cohesive detail with continuous tonality that anchors instruments and vocals.
- Surprising bass extension to ~40Hz with light-footed, well-controlled ported performance for a compact tower.
- High-quality parts and a hand-wired DRIM crossover deliver coherent imaging and solid build pedigree.
&
Cons
- Dynamics and low-end slam improve noticeably with more powerful amplifiers; performance steps up past ~25W.
- Recessed terminal cup makes hand-tightening spade connectors awkward compared with banana-friendly posts.

Bass
91/100
Ported 16cm woofer extends to ~40Hz (-3dB) and reviewers repeatedly call out its deep extension 'for a compact short tower'. Bass is described as light-footed, well controlled with no port bloom; best-amp scenarios revealed even more low-end depth.
Mid
93/100
Review praises continuous tonality and a burnished, weighty vocal sonority without harsh sibilance. Midrange gives strong instrument body (e.g., cello portrayed at distance) and excellent detail density that anchors the presentation.
Treble
90/100
25mm ring-radiator tweeter and measured 40kHz bandwidth deliver high detail density while remaining 'warmer, slower and softer around the edges'—refined top end with no reported grain or brightness.
Soundstage Imaging
91/100
Reviewer notes 'immaculate sorting across a feathered-out soundstage' with clear layering and intelligible low-bass placement—good width, depth and image clarity for the form factor.
Dynamics
88/100
Dynamics scale with amplifier power: performance steps up past ~25W and shows strong headroom at 90W. Punch and macro dynamics are very good for its size but depend on a capable partner amp.

Build Quality
90/100
High-quality parts cited (Jantzen PP caps, wire-wound resistors, baked copper inductors) and well-engineered drivers; only minor gripe was the recessed terminal cup that makes hand-tightening spades less convenient.
Features Connectivity
80/100
Passive baseline applied. Single-pair terminals accept banana plugs; hand-wired DRIM crossover on a substantial PCB is a positive but no bi-wire/extra connector features are present.
Value for Money
88/100
Reviewer describes the Sensa as being 'keenly positioned' (noting ~€700 differential vs a reference) and implies strong performance-per-euro through dealer channels; good value though not described as a 'no-brainer' bargain.
