Sointuva AWG Stand Mount Speaker (PAIR)

SKU: Sointuva-AWG-Pair

USD $4,011.75

The Sointuva WG is a stand mount speaker featuring state of the art drivers from Purifi and SB Acoustics with beautiful solid wood or painted cabinets.

Class leading technical and subjective audio performance.

Please note: As this product is custom manufactured to your aesthetic specification shipping lead time is approximately 4 weeks. Please contact [email protected] to discuss the available speaker finishes.

This speaker is sold as a stereo pair.  However, single speakers can be purchased.  Please contact [email protected] for more information.

We are very excited to present an update to our award winning Sointuva WG speaker.  The new AWG variant now features Purifis’ incredible PTT6.5W04-NAA-07 aluminium woofer which provides even lower bass extension and distortion compared to the previous fibre/polypropylene variant previously used in the WG.  We have also improved and further optimised the crossover providing a more linear frequency response and smoother sound power.

Sointuva is a Finnish word meaning “musical harmony” and March Audio believes this very aptly describes the performance of the Sointuva AWG speaker.

Our design objective was to produce a speaker that is moderate in size yet possessed exceptionally deep and warm bass, with sweet crystal-clear high frequencies and very low distortion.

The stunning performance and sound of the original Sointuva WG culminated in winning Sound And Visions “Best Standmount Speaker 2023” award.  The new Sointuva AWG refines this amazing performance and sound still further.

Technology

Purifi Aluminium Cone Woofer

To achieve this objective we investigated and tested a great number of drivers, but none came close in performance to the Purifi PTT6.5W04-NAA-07.  This driver is a 6.5” driver that truly cracks the extended-stroke code. PURIFI’s research has identified the parameters that have so far prevented extended stroke drivers from breaking through in truly high performance audio.

Purifi has taken care to optimize the various distortion mechanisms separately, thus guaranteeing that any measured improvement truly reflects a real audible improvement no matter what the signal is. Accurate mathematical models are developed for the motor, suspension and the vibro-acoustics of the dome and surround. These models clearly explain several distortion mechanisms in each domain, which provides fundamental insights into better ways of constructing the motor, cone and suspension. Finally, the same models are used to numerically fine-tune the geometry. This way of working reliably reduces multiple distortions mechanisms which secures low IMD for complex signals.

The combination of the above characteristics results in a compact long-stroke driver that delivers complex sound with a clarity and lack of effort that was previously the exclusive province of large-cone short-stroke drivers. Additionally, thanks to the small cone size, the driver has excellent midrange reproduction.

ptt6.5PR NA2 05

Dual Purifi PTT6.5PR-NF1-01 passive radiators are used to on the rear of the speaker to extend the low frequency response.  They also eliminate some of the problems associated with ported designs such as port noise.  They provide the tightness of bass associated with closed boxes with the added extension of ported designs.

These small speakers behave like much bigger devices and the anechoic low frequency response is only -3dB down at 37Hz.  This equates to an in room response that reaches well below 30Hz. This extended response negates the need for a sub woofer when used with music.

To complement the exceptional performance of the Purifi woofer we needed an exceptional tweeter.  The SB Acoustics Satori TW29BNWG Beryllium Dome Tweeter fitted the bill perfectly. Sweet and detailed with exceptional clarity and very low distortion.

The integrated waveguide controls the directivity of the tweeter allowing it to perfectly match that of the woofer at the crossover point.  The controlled directivity also ensures the indirect sound from reflection’s within your room accurately match the timbre of the direct sound from the tweeter.  This provides a much more cohesive sound that is more consistent in different rooms.

The crossover filter utilises high quality components including Jantzen capacitors and low loss air core inductors which minimises distortion and maximises sensitivity.

 

Cabinets

Not only did we want to provide aural harmony with the Sointuva but also aesthetic harmony.

The Sointuva is manufactured to order so the cabinets can be finished to your exact specification.  We can provide paint finishes in any colour you like from the RAL colour system.

Primary woods available include:

  • Jarrah – Eucalyptus marginata
  • Blackbutt – Eucalyptus pilularis
  • Tasmanian Blackwood – Acacia melanoxylon
  • Wandoo – Eucalyptus wandoo
  • Sheoak – Casuarina
  • Tasmanian Oak – Eucalyptus regnans
  • Baltic Birch Ply

Please contact us at [email protected] to discuss your preferred finish.

The cabinets also perform an important function with respect to the sound quality.  March Audios expertise with vibration analysis ensures the cabinets have appropriate bracing and damping to minimise colouration.  The rounded edges are not just for aesthetics, they also minimise the effects of diffraction.

 

Reviews

The Sointuva WG is receiving fantastic reviews from both customers and the audio industry.  The new AWG variant further refines the performance and sound

Most visiting speakers dont match our references; some outperform them. None has done so with quite the immediacy of the March Audio speakers…

You must hear March Audio’s miracle speakers…

Objectively speaking, I believe this is the best passive speaker I have measured to date. It rivals linearity and directivity on par with some of the best speakers I have seen…

These sound awesome…

Performance

Superb sound is derived from superb technical performance.  The Sointuva AWG has been been designed and tested to ensure it delivers both.

For the technical amongst you, some measurements.  The speakers have been independently tested and data collected by Warkwyn Acoustic Consultants using a Klippel NFS system.

The Sointuva AWG is one of the highest rated speakers at Peirre Auberts SpinoRama speaker test website:
