After a lot of reading and research of the physics involved I began to develop an appreciation of the prior art, while at the same time noticing how some contemporary horn designs had fundamental flaws that undermine the advantages and introduce additional problems. I wanted to take the concepts from the early horn era and push them further, taking advantage of the technology of today in terms of computing, simulation, CAD-CAM and manufacturing advancements, and use it to advance horn performance whilst retaining classic horn virtues and sonic performance.\"\u003c\/p\u003e\n\u003cp\u003eThe Symphonia is the result of an intensive five year research and development program in horn speaker engineering\u003c\/p\u003e\n\u003cp\u003eThe development of the Symphonia’s tweeter was spread over a three year period. I was always mesmerised by the sound of a true ribbon, especially Raal’s designs, but usually direct radiating ribbons lack the punch and dynamics of a high-frequency compression driver. On the other hand, no compression driver could ever deliver the detail, accuracy and bandwidth of a true ribbon transducer. So we began research on whether it was possible to combine the two approaches to get the best of both worlds.\u003c\/p\u003e\n\u003cp\u003eA normal ribbon is not designed to operate at high acoustic pressures typically present at the throat of a horn. It soon became clear a special ribbon would need to be designed. After modification and experimentation on the Raal tweeter, we found the end result to more than meet our expectations. However, horn loading the ribbon still presented challenges. We were reluctant to use conventional solutions such as wave guides or directivity control apparatuses that would be inadequate for the task, so we endeavoured to find a new approach.\u003c\/p\u003e\n\u003cp\u003eThis lead us to design a horn flare that specifically loaded the ribbon as a true horn. Nevertheless, the line source emission characteristic of the ribbon made this extremely difficult. Diffraction is secondary sound emission, and takes place in geometric anomalies, transitions of geometry and changes in curvature. It’s very much audible and almost impossible to eliminate. In horns, diffraction is present at the horn termination for round horns. In rectangular horns the problem is more pronounced.\u003c\/p\u003e\n\u003cp\u003e The solution was the implementation of our diffraction-less 360 degree horn technology. We designed the horn flare to expand to 360 degrees, while maintaining the flare curve’s second derivative constant, keeping the curvature slope constant. Precise measurements were made of each iteration in an attempt to match the simulation and theory to its real-world acoustic performance.\u003c\/p\u003e\n\u003cp\u003eWe found variations of just 0.2mm to have detrimental effects on the horn’s performance. Manufacturing them to specs from wood was also challenging. In the end, a total of fifteen different flares were designed, built, measured and eventually discarded before we settled on the final design that performed as we wanted.\u003c\/p\u003e\n\u003cp\u003eThe ribbon horn combination response is shaped to measure flat from 3KHz upwards. It delivers detail and resolution associated with only the very best ribbons, with the solid punch and dynamics of the very best high frequency compression drivers. Distortion characteristics at 114db are lower that those of the best dome tweeters at 95db. What’s more, the diffraction-less nature of the horn enclosure gives the tweeter unmatched time domain performance.\u003c\/p\u003e\n\u003cp\u003eWe believe that bass delivered from horn loaded drivers are unmatched in performance, as long as the horn in properly designed. Folded horns suffer from three major factors:\u003c\/p\u003e\n\u003cp\u003eUsually to short in length for the bandwidth used. Shorter horns and small mouth-area bass-horns, have large frequency response ripples, and strong coloration.\u003c\/p\u003e\n\u003cp\u003eThe horn is often not folded correctly, the horn flare is formed by conical sections of wooden sheets, with sharp angles and many parallel surfaces, trying to resemble something like a true horn flare.\u003cbr\u003eHorns and bass horns in particular, submit their internal walls to extreme pressures. Plain sheets of wood are just not appropriate for this task.\u003cbr\u003eThe Bass horn used is a 3.3m long horn with very large mouth area for the bandwidth used, providing excellent performance in bass extension and weight, with the lowest coloration than any other folded horn.\u003c\/p\u003e\n\u003cp\u003eThe horn flare, is a true tractrix flare, formed by stacked sheets of plywood, carved to formed a true 3.3m long tractrix horn, properly folded without any internal sharp angles and geometrical deviation from a the tractrix flare.\u003c\/p\u003e\n\u003cp\u003eThe stacked plywood construction, provides 10 times the stiffness (along the horn axis), compared to conical horns formed by sheets of wood, also constructed with much reduced weight\/stiffness ratio, providing minimum energy storage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEXTERNAL CROSSOVERS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe external crossover, consists of three constant group delay filters.
