The Third Generation of the Overture Series
The Overture MK3 series represents a major evolution of AudioSolutions’ entry-level loudspeaker range.
Earlier Overture MK2 models carried the O2-series designation, while the redesigned MK3 generation uses O3-series model numbers.
The changes extend well beyond appearance. AudioSolutions reworked the cabinet architecture, driver implementation and crossover design to incorporate lessons learned from its more advanced loudspeakers.
The result is a range intended to preserve the manufacturer’s emphasis on natural timbre, controlled dynamics and convincing spatial presentation while remaining accessible to a wider audience.
A Two-Way MTM Floorstanding Design
The Overture O303F uses an MTM, or Midwoofer-Tweeter-Midwoofer, configuration.
Two 152mm ER paper-cone mid-bass drivers are positioned around a centrally mounted 25mm silk dome tweeter.
This symmetrical arrangement is designed to provide a controlled transition between the mid-bass drivers and the high-frequency unit.
AudioSolutions combines this driver configuration with a carefully designed crossover operating at 3,000Hz.
The objective is coherent reproduction of voices and instruments, along with a stable stereo image and controlled dispersion through the important midrange and treble frequencies.
AudioSolutions Sectional Box-in-a-Box Cabinet
One of the most distinctive technical features of the O303F is its Sectional Box-in-a-Box cabinet construction.
This architecture is inspired by technology originally developed for the manufacturer’s higher-end Virtuoso series.
Instead of relying on a conventional single-wall cabinet, AudioSolutions employs separate internal and external cabinet structures connected through a specialised damping layer.
The result is a multi-layer enclosure designed to manage unwanted vibration and reduce the storage of mechanical energy within the cabinet.
By controlling these effects, the manufacturer aims to minimise cabinet-related colouration and allow the drivers to reproduce musical information with greater precision.
Three-Layer Vibration Control
The cabinet architecture incorporates three important elements:
Inner cabinet: A relatively lightweight but rigid structure designed to provide structural support and transfer unwanted mechanical energy.
Outer cabinet: A heavier enclosure designed to provide mass, rigidity and damping.
Polyurethane layer: An intermediate damping material intended to assist energy transfer and dissipation between the two cabinet structures.
When a loudspeaker operates, its drivers generate forces that can excite resonances within the enclosure.
If those resonances persist, the cabinet itself can contribute unwanted acoustic energy, potentially affecting clarity and tonal accuracy.
AudioSolutions developed its Box-in-a-Box system to manage this behaviour through controlled energy transfer and damping.
The manufacturer’s goal is to reduce prolonged cabinet vibrations while retaining the structural integrity required for accurate reproduction.
25mm Silk Dome Tweeter with Mini-Horn Loading
The O303F uses a customised 25mm silk dome tweeter mounted within AudioSolutions’ distinctive Mini-Horn profile.
The Mini-Horn is not simply a decorative surround.
According to the manufacturer, its geometry is developed to control acoustic loading around the tweeter diaphragm and help manage unwanted resonant behaviour.
The design is intended to improve the driver’s operating conditions, particularly as playback levels increase.
By using the acoustic properties of the horn profile, AudioSolutions aims to support smooth high-frequency reproduction, controlled dispersion and good sensitivity.
For listeners, the intended benefits include natural vocal overtones, clear instrumental harmonics and detailed treble without unnecessary aggression.
How the Mini-Horn Works
Soft dome tweeters are valued for their smooth and refined characteristics, but their diaphragm movement must remain controlled over a wide operating range.
AudioSolutions describes its Mini-Horn as an acoustic damping technique rather than a mechanical stiffening structure attached to the dome.
The shape of the horn influences the acoustic impedance experienced by the tweeter.
This allows the manufacturer to tune the acoustic loading around the diaphragm while preserving the low moving mass of the soft dome design.
The aim is to achieve a carefully controlled high-frequency response with good transient behaviour and reduced unwanted distortion.
Dual 152mm ER Paper-Cone Mid-Bass Drivers
The O303F is equipped with two customised 152mm ER paper-cone mid-bass drivers.
The driver technology is inspired by work undertaken for the AudioSolutions Figaro family.
Paper-based diaphragms remain popular in high-quality loudspeaker engineering because their mechanical characteristics can be tailored through material composition, geometry and damping.
AudioSolutions combines its chosen driver construction with the O303F cabinet volume and crossover arrangement to create a balanced presentation across the bass and midrange frequencies.
The dual-driver configuration is designed to reproduce both the body of acoustic instruments and the dynamic energy of more demanding recordings.
Optimised Bass Reflex System
The O303F employs a bass reflex loading arrangement with a carefully shaped, high-flow port.
The manufacturer specifies a rounded port flange intended to manage airflow and reduce unwanted turbulence associated with air movement at higher playback levels.
Combined with the drivers and cabinet design, this contributes to the speaker’s specified 37Hz low-frequency extension in an in-room environment.
Actual bass performance depends on room dimensions, placement, boundary reinforcement and the connected amplifier.
Phase-Conscious Crossover Engineering
The Overture MK3 series incorporates a newly developed crossover network.
AudioSolutions describes the design as phase-linear and employs a substantial printed circuit board with thick copper tracks and high-quality coreless copper coils.
The crossover frequency for the O303F is specified at 3,000Hz.
Careful crossover engineering is important in an MTM configuration because it controls how the mid-bass drivers and tweeter operate together.
The manufacturer’s approach focuses on maintaining coherent output through the crossover region while retaining the individual performance characteristics of the selected drivers.
Premium Loudspeaker Binding Posts
The Overture O303F features substantial loudspeaker binding posts with a frosted satin-silver finish.
These connectors are designed to provide a secure mechanical connection for suitable loudspeaker cable terminations.
Good electrical contact, correct polarity and secure tightening are essential to a reliable loudspeaker installation.
The O303F can be partnered with quality loudspeaker cables, provided their connectors are compatible with the binding posts.
Floor Spikes and Installation Flexibility
AudioSolutions supplies the O303F with floor spikes intended to provide stable support on suitable surfaces.
Protective spike accessories are also described by the manufacturer for use on more delicate flooring.
The spikes use an M6 thread, giving owners flexibility when considering alternative compatible support and isolation products.
The full loudspeaker should be securely supported and correctly levelled before operation.
Handcrafted European Cabinet Finishes
AudioSolutions manufactures its loudspeakers in Lithuania, combining modern acoustic design with an emphasis on cabinet craftsmanship.
The Overture MK3 range is available in standard Gloss Black and Gloss White finishes.
The manufacturer also identifies selected wood-texture alternatives including Oak, Mahogany and Wenge.
This particular Chameleon Audio special offer concerns the Gloss Black finish.
Other finishes should not be assumed to be available at the same promotional price.
Musical Performance and Listening Character
The O303F is designed to reproduce music with a combination of tonal naturalness, precise imaging and engaging dynamics.
Its silk dome tweeter and dedicated Mini-Horn loading aim to provide clarity and refinement through the high frequencies.
The dual ER paper-cone mid-bass drivers contribute vocal presence, instrumental body and bass articulation.
The Sectional Box-in-a-Box cabinet provides the structural foundation for controlled reproduction by addressing unwanted enclosure vibration.
Together, these technologies form a loudspeaker intended to deliver an enjoyable and involving presentation across a wide variety of musical genres.
Listening impressions are subjective and will depend on the partnering equipment and listening room.
Independent Review: Opus 51
French high-fidelity publication Opus 51 published a dedicated review of the AudioSolutions Overture O303F in June 2022.
The review explored the speaker’s construction and listening performance with music ranging from vocal recordings to orchestral works.
The reviewer particularly appreciated the loudspeaker’s tonal qualities, three-dimensional presentation and ability to communicate musical expression.
The article awarded the O303F 19/20 for value for money, alongside strong assessments of construction, imaging, timbre, dynamics and transparency.
With a nominal impedance of 4Ω and sensitivity of 90dB at 2.83V/1m, the O303F can be considered for a wide range of high-quality integrated and power amplifiers.
Because it is a nominal 4Ω loudspeaker, an amplifier that is stable with a 4Ω load is recommended.
The manufacturer specifies nominal power handling of 110W RMS and maximum unclipped power handling of 220W.
These values describe loudspeaker power handling and should not be interpreted as a requirement to use an amplifier of exactly 110W.
Amplifier selection should take into account room size, listening distance, desired playback level and the amplifier’s current-delivery capability.
Chameleon Audio can assist with amplifier matching for the Overture O303F.
Speaker Placement and Room Integration
The O303F’s relatively compact floorstanding dimensions make it suitable for a variety of domestic listening spaces.
For the best results, allow space around the loudspeakers and experiment with their distance from nearby walls.
The bass reflex system and room acoustics can influence the quantity and quality of low-frequency reproduction.
Positioning the loudspeakers symmetrically and adjusting their toe-in can also help optimise stereo imaging and tonal balance at the listening position.
Use the supplied support hardware and follow safe installation practices, particularly on uneven flooring.
