Satorique Petit, the midrange reference
Report from Karsten
My first rough idea
Since I could get cheap blanks, wanted to build it a little differently than in some construction reports here and I trust myself craftsmanship, I decided to make the housing itself. Whereby the 3D milled fronts from Intertechnik are already tempting. Also I don't want to ask more often if I could get this or that cut and milled. So I built 7 cases. The dimensions I got here from the report and then as well as it was possible for me in Sketchup planned.
It should be 4 speakers S06, 2 speakers S4 and a center. So I could easily run a 5.0 system and in another room still 2 speakers or build a 7.0 system.
My cut and milled wood for the 7 speakers
Then I laid each board flat and saved the drawing as a DWG file (Autocad file format). Here, a friend has then created CNC programs out of it and thus I had quickly cut boards. The company does not have normal MDF, so I got some with white primer film. This is quite hard on the primer film and behind it like normal MDF. I also didn't want to use so many different material thicknesses. My Petit is a bit bigger than the case of the S0.5 anyway, so I don't have less volume if I use thicker MDF.
Imagination transferred to wood
For the assembly I bought some screw clamps, clamping straps, glue and MDF filler. I borrowed a planer, scraper, router and a groove cutter.
For the required boards I created a few templates in scale 1:1 and cut them out to fit and then draw my bevels on the boards.
Draw in and set grooves
Now I drew in at the boards where I wanted to use the groove cutter.
After I got out again at a 45 degree slope on the other side, I did not set any more grooves in such places.
Create roundings
Nun habe ich das Brett für den Bassreflexkanal und die Verstärkung mit den Hobel abgerundet und danach noch etwas nachgeschliffen.
Use screw clamp capacity
Always some glue as long as you have free screw clamps. I usually left these alone for 4 hours or more.
Use drying time.
In the meantime, I then worked on other parts. Like, for example, to deal a little with curves.
More difficult, but special
Due to the curves, it was a little more difficult, because it should be 4 quite similar looking housings. But the speakers are normally always a little apart and therefore small differences are not so quickly noticeable.
Take improvements from other reports
Auch hatte ich in anderen Berichten gesehen, dass innen in die Einlassung für die Lautsprecher eine Schräge gefräst wurde und somit hab ich dies auch gemacht.
Last glue joint
Now that all the preparations were ready, the front should be glued.
After everything was well cured, it went on to plane and grind the appropriate curves.
When creating the curves, but then the speakers were partly a little too round and I was already thinking, I make 2 speakers so and 2 others then with less curves! But I then came up with the idea, I reduce the upper round edge. For this I have then beveled front and the upper surface, thereby this rounding was reduced and thus I could design all speakers very similar.
Daylight
Then I used MDF filler to get my hole, which I had created with the groove cutter in a board, smooth again. I puttied and sanded several places a few times. To make the speakers all very similar, I first wanted to take negative pictures and compare them, but this I quickly gave up. In daylight I had then created the following pictures and thought it turned out quite well.
Completion
The speakers went to the painter and after applying the light filler, the uniform color made it easier to see the areas that were not yet so well done. So it still had to be sanded and filled. I had decided on the color white, since it is a timeless color, which also fits into the most diverse interiors and one sees dust less than with black.
In the meantime, I had also noticed another mistake that I had made in my construction. I had taken the dimensions from the drawings, but had not calculated anything extra for color. The chassis didn't fit easily without paint and filler, you can certainly pull the chassis in and then they sit tight without screws. But I wanted to get to the electronics at any time and so I scraped out the paint in the holes and sanded until the chassis fit in well. I also misjudged the troughs for the tweeter terminals on all the cabinets and had to rework them. Fortunately, all this is no longer visible from the outside.
The rest of the assembly was quickly done by the crossovers made by Marcus. The result of the small speakers now looks like this.
I am satisfied with the optical result so far and also corresponds to my planning.
A speaker must not normally look good, he must sound good. I was also very excited and at my first listening but somewhat surprised, it came extremely much bass from the speakers, but at low setting came nix over.
Marcus the case described and he told me that this is a high-class speaker and it must be due to the sources. Hmmm, it took me a while to find the error, it was on my phone! There times updated the software and now the speakers play as I imagined it.
The small Sabaj has as a player my cell phone via Bluetooth or my notebook via cable, because I have not yet got a Bluetooth connection. The 2 x 80 watts seem to fit very well to these speakers. The amplifier has 36 volume positions. However, if you increase the bass, the amplifier distorts and the sound becomes unclean at higher levels.
The small speakers are quite amazing.
Here comes out of a very compact speaker a bass with which I did not expect at this size. It is always a pleasure to use the speakers for music and also for movies. Since the speakers are assembled, they have played almost every day for several hours. More often than not, the thought crossed my mind that if I hadn't finished the cabinets for the S4 and the Center, I probably wouldn't be building them. But I'm already clear, more bass has the S4 and so I'm still looking forward to the completion of S4 & Center.
Closing
The speakers took a lot more time than it took to write a little report here. But it was a lot of fun and if I could turn back time, I would do it again.
For anyone thinking about such a project, visit Marcus and listen to the speakers.
