    • Hi Stefan, I have come across what you’ve explained above (but will never remember all the terminology), these topics lead me to read up on the Huygens Fresnel Principle (and giving up quite quickly).  I never expected as much as +-3db from the baffle edge or lip of the drivers.  I also understood the level of the effect relates to the wavelength and driver position, I tried to minimise some of this in the updated design. Considering the position of the illuminator & tweeter relative to the baffles as a whole, the baffle shape, the fact I am planning on recessing the tweeter and rounding off the edges of the baffles; I am happy to proceed without flush mounting the other drivers for now but it is still possible to cut out recesses for the drivers with the waterjet (I asked this question). As I’m not a speaker designer, a large part of my strategy is to test and measure...  I had planned on trying to measure everything, including these effects in a few practical tests consisting of temporarily adding a board (foamex or similar) that reproduces a flush mounted finish.  Another option I had considered was adding a chamfered ring around the outside of the drivers.  I would like to mock-up and measure the three situations below in order to decide upon what I need to do for the best results.   I also realise if diffraction is more of an issue than I expected then I will also need to address the gaps between the baffles.  Common sense also plays a part when you consider there are so many box speakers in the world (with square edge cabinets).  I assumed if the effects of a square edge baffle or cabinet (or even the driver when not flush mounted) were that dramatic then all we would see are flush mounted drivers with rounded off edges on the cabinet/baffles (but that isn’t the case).  I'm going to learn a lot by testing. Thank you for all the info, you are a star!  I am more than happy to donate some of my time if you need any help getting your web-site together.  This is part of my day job!

    • Focal Sopra - Reveal The Invisible INNOVATIVE AND SOPHISTICATED DESIGN Following on from Utopia and keeping in line with all Focal loudspeakers, the design of Sopra is the result of a very close collaboration between designers and engineers, a passionate quest aiming to conciliate complex constraints, experience, as well as sophisticated and innovative solutions, and all of this would have to be almost invisible, leading to something obvious, immediate simplicity for the pleasure and the purity of an unforgettable listening experience. The Sopra line is destined for sound enthusiasts. When expectations are so high, the design must provide solutions which go far beyond aesthetics and shape. This represents a great deal of work in terms of industrial design, which must serve acoustic experts and favour performance, whilst bringing together the qualities expected of an object which will be integrated into very elegant interiors and décors. Sopra’s structure is articulated around the intermediate section, which, besides giving a very strong identity to the line, is a structural element which contributes to several technical solutions. This injected polyurethane component allows for the upper and lower cabinets to be inclined for the "Focus Time" (where the audio sources are all at the same distance from the listener for an acoustic convergence of the channels). The compactness and the harmony of the proportions of this line are the result of very advanced research. Substantial efforts were made to give the front a tidy appearance, particularly around the speaker drivers, to ironing out any aspects which could afflict the acoustics or the appearance. The flush cloth frames and the lacquered finishes allow for all sides of the loudspeaker to be the same. This was a real manufacturing challenge for our cabinet-making facility in Bourbon-Lancy (Burgundy, France). The main theme of Sopra is deliberately uncluttered, though it still offers connoisseurs the opportunity to enjoy all the small details. The grille with an incremental meshing motif protects the Beryllium tweeter and gives it a strong identity. This motif is repeated for sealing the curved back panel of the middle section. The terminal board, the thumb nuts and the adjustable spikes have all been specially designed for Sopra, as have the few visible screws, all of which were manufactured by watchmaking experts. https://www.youtube.com/watch?v=8UGIMHQe1Vo
