Rafa Sardina about SQUARE ROOT

Square Audio visited Rafa Sardina (Los Angeles based 35-time nominee and 12-time Grammy-winner producer/mixer/engeneer) to show SQUARE ROOT active near-field monitors and get his opinion about how they perform. It is also worth to mention that Rafa`s home studio is one of the best in terms of acoustics and with a crazy amount of top notch audio recording and processing gear. Ear candies, what else to say!

When we fired up SQUARE ROOT his impression was that they perform very well in comparison with his arsenal of monitors he is used to work with every day. In his opinion SQUARE ROOT monitors are great for accurate moderate/low level recording/mixing. When told about SQUARE ROOT Kickstarter campaign he totally supported it and said the price point there for a pair of monitors is absolutely cool!

SQUARE ROOT Idea

Loudspeakers distort sound, some more, some less. Only when they do it less than a human ear can perceive as a distortion - they sound true and natural to us, just as a live performance would do. Not many speakers can accomplish this and those are expensive for a good reason. We at Square Audio have created such speaker that we named SQUARE ONE. When we first heard it playing - we were floored. Yes, we - creators of it, were hearing a true sounding gear for the first time.

But there still was a problem: this non-compromised reference-grade loudspeaker was not exactly what a musician would be able to afford and use every day. That's why we decided to try to compress all the benefits of a unique point source speaker into a size and price that would suit all the needs of a typical musician. That's how the SQUARE ROOT was born.

The Product

SQUARE ROOT is compact multipurpose near-field loudspeaker with linear phase and frequency response and to understand advantages of SQUARE ROOT, we need to look at the same category near-field monitors available on the market. And almost every monitor is a 2-way monitor with tweeter on top of the woofer. With conventional 2-way design you get several problems:

Conventional 2-way speaker

  • Distortions at crossover region
  • Sound is radiated from two drivers, not a point source
  • Different materials of tweeter and woofer causing timbral distortions
  • Usually woofer has stiff suspension, loss of detail and and compression of low frequencies is introduced
  •  When combining two drivers, phase distortions are introduced which means that frequencies arrive at different time.
  • Usually with conventional passive or active equalization frequency response is not ideal and source material coming from such speaker is colored 

Key advantages of SQUARE ROOT

  • In SQUARE ROOT a single very high quality full-range driver is used
  • No crossover introduced distortions
  • Sound is radiated by one driver and from one point, a true point source
  • Full-range driver in SQUARE ROOT has low moving mass, long excursion and soft suspension. Therefore very detailed low frequencies and very low compression is achieved.
     
  • By using a single full-range driver, very linear phase response is achieved and frequencies arrive in time
  • In SQUARE ROOT a powerful DSP processing is used to achieve very linear frequency response. Therefore sound reproduced by the SQUARE ROOT is much closer to source

Tech Specs

  • Full range, near-field, bass reflex system
  • Frequency response: 40Hz-22kHz (+/-2.5dB)
  • Phase response: +/-10 degrees (250Hz-20kHz)
  • 103dB max SPL
  • Class D amplification
  • DSP filtering
  • Dimensions: D 10'' (25cm), W 8'' (21cm), H 14'' (35cm)
  • Weight: 18.7lbs (8.5kg), each speaker
  • Working distance: up to 7' (2m) max

Connections

  • USB service port
  • Analog In (XLR Balanced)
  • AES 3 Digital In (XLR Balanced)
  • Analog Link (XLR Balanced)
  • AES Through Digital (XLR Balanced)
  • Mains Input 115/230V

SQUARE ROOT components

Enclosure - Made from top quality 0.71" (18mm) Baltic Birch. Two chamber design that helps to reduce standing waves inside enclosure

Full Range Driver - 5" (12.7cm) multiform shallow cone, ultra thin nomex spiders, thin-wall light mass coil

Amplifier - flat, fully load-independent frequency response, low output impedance, very low, frequency-independent THD, Very low noise, fully passive loop control

Digital Signal Processing Device - for active filtering, featuring balanced analogue audio input, balanced analogue and digital audio through loops  and AES/EBU input


Power Supply - high efficiency switch mode power supply, with extremely small form factor and low EMI (electromagnetic interference)

Current Status

Until launch of the Kickstarter campaign, commercial prototypes of SQUARE ROOT speakers have been fully finished. This includes: final choice over acoustic design, selection of best components, samples of assembled products, completing measurements in a lab and field.Quotes and delivery timelines from suppliers of key components have been obtained. Everything is ready for successful scaling into manufacturing of first batch of SQUARE ROOT speakers.

Risks and challenges

Manufacturing: Square Audio hand-assemblies final SQUARE ROOT products in-house from components that are ordered from trustworthy suppliers worldwide. In order to manufacture SQUARE ROOT speakers, we work with three major types of contract manufacturers - those for drivers, enclosures and electronics. Therefore the biggest risk to make and deliver our final product is related possible delays in production and delivery of drivers, enclosures, electronics to Square Audio for tuning and assembly before shipping products out to our customers. We manage the risk by using well-know components’ suppliers we personally have previous business experience with, as well as by trying to source most critical components from several reliable sources, to avoid “putting all eggs in one basket” situation.

Quality control: certain risk is small differences in technical parameters of the drivers and how they work with the speaker enclosure. As we are totally dedicated to deliver every single speaker with perfect technical parameters, we will tune each of them with the highest possible precision during the quality control process. The built-in DSP processing allows us to deliver constant quality for all of SQUARE ROOT speakers.

Logistics: Global shipping of products of the size and weight of Square Root may become a challenge. Our presence in both California and Europe allows us to be more flexible in terms of deciding of where the final assembly and testing of products will happen for each geographic market, and arranging of shipments of components and semi-assembled products accordingly.
