I wanted to quickly introduce you to my SB 36 and say a few words about it. Before I begin, let me say a big THANK YOU for this wonderful website, to the community members and above all to “Köder” from the forum. Thank you for the fantastic loudspeakers and for all your help in my decision-making process. Especially Köder, because he was the one who really got me interested with his Symasym version and his SB 417.
So I was on the hunt for a small but elegant project for my guest room / home office / lounge. Since the room is only about 15m² and the listening distance is only 2.5 m, I was looking for smaller boxes. After a lot of back and forth, I ran across the SB 18 on Loudspeakerbuilding.com. There were nothing but positive reports about this speaker. So I got in the car and drove over to the listening studio. Arrival 4:30 pm, departure 8 pm. What an afternoon! I felt like it was over in no time. My last visit had been about 9 years earlier, and I still had very positive memories of it. Once again, I was not disappointed. I would recommend to everyone that they visit the studio and have a consultation. Unfortunately, though, neither the SB 18 nor the SB 26 were available for a listening session at the time, just the smaller SB 15 and the large SB 417. But I was assured that the tonal characteristics of the SB series were very similar.
No sooner said than done – the SB 18 assembly kit landed at my front door just a short while later. Over the next few days I had to get a couple of old boards to build the test cabinet. What awaited me was already pretty impressive. Rarely have I heard a loudspeaker that sounds as balanced as this one. No matter what the volume, everything is finely resolved and you don’t have the feeling that something is missing or too dominant. I always have some trouble with the sound description, but I can’t remember ever hearing such a fine box before during countless listening tests at typical hi-fi stores. And if I did, it was outrageously expensive. Of course, that’s my subjective personal opinion.
Still, I couldn’t shake the idea of building the SB 36 – after all, the extra cost was less than 100 euros for each box. So I went back to the listening studio, talked to Udo about it, and ordered all of the parts for the SB 36. This time I didn’t want to build a test cabinet; I went straight for the final cabinet. In keeping with the motto “Build it the way you want it,” I came up with a different cabinet shape. I opened SketchUp and constructed a new cabinet (naturally with the same volume and BR tube).
There are pictures of the assembly process too, but not very many.
I glued the crossovers onto a Plexiglas board and screwed them to the back wall behind the lower bass.
The boxes were veneered in figured walnut.
The results confirmed my decision. Everything that the SB 18 already impressively demonstrates, the SB 36 can do just a bit better. Naturally it also offers significantly more pressure, so the fun factor is even higher. Finally, the tweeter is a little more subdued, which works better in my room. Since then I’ve been diligently testing it out, now with a borrowed tube amplifier. That rounds everything out even more. I can only hope that my planned Symasym amplifier works just as well. I am always fascinated by how much information the loudspeaker provides at a low volume. You have the feeling you are getting to know familiar songs for the first time. As far as the volume, all I can say is that the SB 36 is completely impressive in my living room, too. That should be enough for now.
