British proposals for new 4 ch surround in Windows

2 new products that go well together !

The Tannoy Gold 5 is interesting for music playback with 4 speakers in the latest Microsoft configuration.

This configuration is available on a PC with analog output for multi-channel audio. The new solutions of the British Tannoy in this Microsoft configuration have also worked well for the playback of digital recordings from quadraphonic vinyl records in the SQ and QS systems

200 Watt Bi-Amplified Nearfield Studio Reference Monitor with Proprietary 5" Dual Concentric Point Source Technology
  • It measures 294 x 183 x 252 mm, which is the height of an A4 sheet, and becomes almost invisible in the living room. 
  • The total power of 4 x 200 W allows you to play music even in a very large room without amplifiers distortion. It has a stereo mini jack that has the function of "transmitting the signal" to the next speaker, which makes installation from a PC very easy. 
  • There is also an eco-friendly auto "sleep" feature, which is beneficial with increasing energy costs. 
  • 200 watts gives SPL 107 dB

Class-AB system with transducer-matched LF and HF bi-amplification for accurate dynamics

Obrazek
Why Class-AB? The duty of any amplifier is to take a small input signal and turn it into a louder output that maintains the characteristics of the original signal, and to be large enough to meet the demands of the loudspeaker it drives. While Class-A amplifiers sound great at low volumes, they waste a tremendous amount of power that is lost as heat when asked to output hundreds of Watts. And even though Class-B amplifiers are much more efficient, they tend to bring a great deal of distortion to the mix. A Class-AB amplifier combines the linear performance of Class-A with the higher efficiency performance of Class-B, producing a much better amplifier design for loudspeakers used in critical listening environments
 
4-channel music playback is more precise with Dual Concentric

Discrete driver speaker systems using non-coaxial sources have an inherent design flaw in that each drive unit is an acoustic source of its own. While the components are physically aligned on one axis, they are displaced in source and can only be coherent at one specific listening point. When delays are applied to compensate for driver alignment, signals can only be aligned along a narow listening plane on one axis. Even systems with ratatable horns suffer from a significant 'suck-out' in the crossover region, and no amount of DSP processing can correct this phenomenon. The constant directivity characteristic of the Dual Concentric overcomes such time alignment problems

Dual Concentric was offered in the 1940s and is constantly being improved


Tannoy has produced coaxial loudspeakers for the hi fidelity home consumer market since the early 1950s. Their "Dual Concentric" drivers early series included in order of introduction: Tannoy Blacks, Tannoy Reds, and Tannoy Golds

The Litle Gold Monitor model appeared in the golden age of hi-fi with the reigning compact cassette. They had a passive crossover and are still used by manufacturers of high-end amplifiers as a reference. Now it has served as a model for the modern active crossover range.



Tannoy Ltd is a British manufacturer of loudspeakers and public address (PA) systems. The company was founded by Guy Fountain in London, England, as Tulsemere Manufacturing Company in 1926". In Britain any PA system is sometimes colloquially referred to as a Tannoy, after the company of that name, now owned by TC Electronic Group, which supplied many of the PA systems used previously in Britain 

There also 2 larger models with a 300 watt amplifiers for a 6.5 and 8 inch Dual Concentric. 300 watts in Tannoy Gold gives SPL 110 dB. 4x 300 watts is enough for even a large room.
Frequency response:
GOLD 7
:
65 Hz – 20 kHz ± 3 dB; 46 Hz – 20 kHz -10 dB
GOLD 8:
54 Hz – 20 kHz ± 3 dB; 40 Hz – 20 kHz -10 dB
 

The small size of Tannoy Gold makes it an attractive alternative to playing music in DVD movies with 5.1 surround sound in the new Microsoft configuration.

 
 It worked also well with the Metropolitan Opera's broadcasts during the pandemic

 
The topic of alternative solutions is discussed in the text   5.1 reference in optimal PC4uMusic configurations

 Quadraphonic vinyl records in the SQ and QS systems

 

SQ and QS quadraphonic vinyl records can be digitally recorded like standard stereo and played with the Microsoft setting for 4 speaker surround sound in Windows.

 
Orthodox reproduction of analog quadraphony requires a decoder which is currently difficult to buy. It is equipment from the 70s of the last century and has a relatively high level of noise (S/N) and distortion.(THD, TIM, DIM)
 
News has appeared in the trade press about a state-of-the-art tube amplifier with SQ for around €5,000, but the Muarah decorer is just a small device with integrated circuits. However, this solution can reproduce the music more faithfully.

 

 
CD-4 discs require recording to 4 digital channels. Equipment for this is now very rare and the same is with such vinyl records. Those who invest in it listen to music with the traditional speaker setup for quadraphony.
 

Active monitors Audio Pro Solutions Coax with SEAS elements in a closed-box, which received a positive review in SoS tests, will provide even better music playback quality, but the price is not fully rational for music playback with 4 speakers in the latest Microsoft configuration. Such an investment is better for orthodox speaker settings for quadraphonic.

 
Tannoy, which has been operating since 1926, has a better balanced offer for Microsoft surround sound. It's strange that SoS didn't test Tannoy Gold.
 

 
Cambridge-based SoS has been operating since 1985 and publishes a high-quality monthly print magazine - The current website houses our continually-expanding archive of authoritative and highly-respected articles, news and up to the minute in-depth reviews (16,646 so far) that chart the impact of technology on the music production and recording processes.Their tests are focused on the music industry, but it's worth checking out.

  1. Tannoy Little Gold Monitor (aka LGM’s) speakers were my first set or dual concentric Tannoys. I was watching these on eBay for couple of years and always wanted a pair. They do not come up on eBay very often, and when they do, they can reach anything between 600 to 1200 GBP. Purchasing mine was a bit of a coincidence, or perhaps the universe was giving me signs to purchase these… at least this is how I had to explain it to my girlfriend at the time :).
    These were collection only from Bristol, which is about 4.5h drive from where I live. This correlated with a business trip couple of days after the auction’s end date. Guess where? Near Bristol… I contacted the seller, made an offer and arranged a mutually convenient collection time. Week after, and I was a proud owner of these beautiful Tannoys.
