  • Inside Sonus Faber Olympica III Speakers

    I thought you all might like to see what’s inside a Sonus Faber Olympica III speaker. As a DIY’er you knew I was gonna take these apart. For the most part I saw what I expected but I was disappointed in the electrolytic caps in the lower end of the crossover. I guess at $14k another $200 in good caps would have ruined the profit margin😏

    Unfortunately PE does not incorporate automatic photo compression so I need to keep going back and forth so I hope I don’t get too many duplicates.

      Last two. The woofers and midranges are nice drivers. This is the first SF speaker where they manufactured their own drivers. Previous versions used mostly scanspeak drivers. Only the tweeter is a little disappointing in this . It’s a little “plastic’y” for my liking.

      unlike some of the older SF speakers this one is MDF. Some of their newer lower end lines are made in China but these are not.

        Hard to tell for sure, but they look like they could use more bracing. Easy and cheap for you, but labor intensive for them.

        You can't be too cynical when it comes to the economics of commercial speakers. They pay for what sells the product, and cut corners with stuff that the ordinary buyer doesn't care about. The drivers do look decent at least; well worth bracing the cabinet to get the most out of them. You might even measure them to see if the crossover can be improved. You might be shocked how marginal the crossovers are, even in costly speakers.

          That is so true.

          I would also point out that the plethora of ferrite core coils is very disappointing, as well.
          Don't listen to me - I have not sold any $150,000 speakers.

            The drivers look pretty serious, though and SF has always been cutting edge on cabinet aesthetics (IMNSHO).

              Hate to diss on your high $ speakers, but for $14k, I would have thought there would be more extensive cabinet bracing and some kind of internal acoustic lining. Drivers look nice. There are times when an iron core works better, price, size, and resistance come to mind, but at $14k why not have big ole expensive air cores in there? And is there anything other than the two screws, supporting the crossover board with all those bobbin inductors on it?
              The looks, binding posts, and feet are sweet.
              How does it sound?

                I bet they feature the drivers in their advertising.

                  I removed all the damping material to see what was I side. They were packed with fiberfill except the HF enclosure also has the walls lined with the foam you see.

                  the crossovers are I. There white tight. No wiggling at all. I did not really look to see how they were mounted but they do have some sort of isolation pad under them.

                  the internal bracing is in there for sure but they are not quite as beefy as I would think but they are very solid and quite heavy. The curved sides help with the rigidity as well.

                  I luckily did not pay anywhere near that much for them. I bought them used but in perfect condition. The boxes are enormous double boxed with three foam forms and they shipped at 110 pounds each I think.

                  I auditioned many new and used speakers at HiFi shops around the NY Tri-State area. Soo many speakers with these small 6 or 7” woofers have what many audiophiles refer to as bass but what I call classical bass. But they have zero bass when it comes to punch, slam, or whatever the rest of us like to hear in bass. The B&W 702 signatures were completely bass-less and the Paradigm Founder 100f had wonderful bass but in terms of imaging and soundstage were a joke in comparison to any of the other “Audiophile” speakers I auditioned.

                  In terms of imaging and soundstage these were the best I ever heard with the exception of the Dynaudio Sapphire’s . Those were simply holographic in soundstage. I also listened to the Dynaudio Contours’s but I felt the SF have better bass. In fact that was the first thing I noticed was how full the SF’s were in bass.

                  I am driving these with a pair of Bryston 7B monoblocks and at low to moderate levels these really give a listening experience that is wonderful. But if your looking for some DJ level volumes, your not going to get that out of these. I would say your probably not going to get that out of any speaker for 6.5” woofers.

                    I do like how SF says they make all the drivers in house but there is a “Made in Denmark” sticker on the woofer. Sounds like they just bought a driver manufacturers in Denmark like Wilson Audio purchased a capacitor manufacturer and started branding their caps.

                      Ultimately, that is what matters, that they please you, and it definitely sounds like you did your homework before spending the $.

                      Of course, being a diy community, do you think you could build something that performs at, or above, this level?

                        Sure we can. The vast majority of high end manufacturers don’t make their own drivers. The vast majority use MDF. We all know the basic building principles and many of the people on these pages have not only the building skills but the finishing skills as well. That’s kind of why I did this post, to show the DIY’ers what’s inside.

                        There are many great budget builds as well and I think those builders truest demonstrate their skills and knowledge. If they had an extra couple of grand to throw into I compromised drivers and components I have no doubt they would perform better.

                        One of the things I enjoy about the SF’s is they are truly a work of art. Just as much a pleasure to look at as they are to listen to. You can run out and spend a few $K on some Klipsch floor standers or some other well known consumer brand that will crank and wow the senses. But when a pair of speakers are stunning to look at it adds an extra level to the enjoyment.

                          I have always enjoyed SF aesthetics, and the few I have had the privilege to listen to have generally impressed me.

                            SF has always been my favorite speaker in appearance. It's the only speaker that when my wife asked me, "can't you do that?" I had to lower my head and admit sheepishly "no."
