Lyra 2-Way Stand Mount Loudspeaker Lyra is a unique 2 way speaker system. It features a new breed of high frequency driver loaded with a very special horn system, complimented by 2 magnesium diaphragm mid/bass drivers in a all aluminium ported enclosure.
Loudspeakers are the final component in the reproduction chain. You will hear all kinds of opinions on the importance of loudspeakers in the replay chain pitched by gurus around the globe. Most leaning to the fact that loudspeakers don't measure very well. They all have considerably high harmonic distortion, limited bandwidth and frequency nonlinearity. Those are the parameters that are easily measured even by amateurs. Other, just as important parameters, are directivity, stored energy, time alignment, those are discussed by connoisseurs and by marketing people and require a higher level of equipment and knowledge to identify. Things like signal to noise (yes speakers have signal to noise!), break up behavior, diffraction interference and others are discussed only among people with true experience and understanding. To measure these properties, you need special jigs and equipment that is usually purpose built. Listing all the shortcomings in a speaker would make you wonder how it even works and yet when you are comparing 2 DACs with 100 times better specification and measured performance on obviously imperfect speakers, you can clearly hear the difference between the DACs. The argument that speakers have the most audible artifacts of any component in the signal chain is true, but it does remove the faults from other components within the signal path. To wit, speaker-induced artifacts are of a completely different character from other electrical components.

Being simple devices, the computer models used to predict speaker behaviors are quite accurate. However, when generating a model the more complex behaviors are often generalized and many variables are assumed. In those assumptions, the errors start to accumulate, until they prevail and the predicted result significantly different from the measured or intended.
The speaker system features an uncommonly high sensitivity rating of 90db, making it suitable for lower power amplifiers. Alternatively, in very large rooms, bass extension is generous considering the size of the speaker and its efficiency. The Lyra is designed to sustain severe levels of abuse without giving in. The filters are constructed with resonance free foil wound inductors and premium Polypropylene capacitors. The all-aluminum body construction is internally damped for any internal vibration and resonance. Styled in the bespoke form of all Thrax products, the value of our speakers is in the knowledge required for design and construction .

As said music is sounds and silence. Everyone tries to improve the sound and we just improve the silence.

Wasn't Thrax an electronics company? What do you know about speakers? 28 years ago, I designed and built my first speaker. Utilizing the current state of the art ribbon tweeter (by Decca) and an Alnico magnet bass unit. It didn’t sound that fantastic at all. The main reason was... It was designed by the book, no thinking involved. Following preset rules and practices, often returns a mediocre (average) result.

During my studies at the Danish Technical University in Copenhagen, on the subject of acoustics, coincidence introduced me to a character named Steen Deulund. This meeting resulted in a new formulation of thought, I realized I knew nothing of speaker design.
A number of books later, I regained enough confidence to point out a good or a bad design from general inspection. Then I realized how little people know about speaker design, but I certainly could identify a good one. I was empowered with knowledge that could be dangerous (joke)!
Leap forward 20 years to an argument in Sofia about tweeters used in high end speakers and which sounds better accompanied by demonstrations and piles of marketing rubbish. Until an older gentleman comes to me and states "you should heard what Plamen has done!". Never paid much attention as Plamen has been designing cinemas and studios for as long as I can remember. However, curiosity prevailed. I decided for a quick listen. The speaker was a prototype, using a ring diaphragm compression driver loaded with a 2" short horn(that is very short) . I was god smacked!

The experience was backed by very thorough paper, written on the subject of intermodulation products of tweeters and sub harmonic distortion, acting as contaminants to the background and reducing signal to noise of the speaker system. Apart from the usual break up modes there was excursion induced nonlinearities, cavity resonances, magnetic modulation, diffraction and other subjects covered.

But the proof of the pudding is in the eating. Building a speaker system as a showcase for this technology seemed the logical next step. Beware, what you hear, just might change your views on speakers!
