I'm trying to have the waveguides printed by materialize.com - however, the STL file does not get imported in the right scale and I need to manually have it scaled up. Does anyone have the right measurements for the waveguide?
The woofer would be something of 6.5" or slightly larger but not most likely from SB. It has a severe break-up around 4-6kHz. No idea what brand or model. BTW is the woofer's frd anechoic or spliced from semi anechoic and nearfield.While patiently waiting for a calibrated mic to turn up, here's a teaser on another speaker I'm working on - a scaled up version of this concept with an augerpro 8" waveguide. Output much higher than the 105 copy.

Hard to get flatten the power response warble around the XO, being a two way. True sensitivity is 88db (not shown). Keens might be able to pick the woofer by the breakup 'hint'
Another bonus is this is a dead plain box speaker, no roundovers.
Funnily enough, its a Satori 7.5”. I get a much worse 5k breakup than any of the published measurements. I haven't seen many other published measurements of this woofer. But it sounds crazy clean. I really like it. This is an older - perhaps one of the first ones - woofer.The woofer would be something of 6.5" or slightly larger but not most likely from SB.

Those look really tidy. SLS with a black finish or something else?Two really good looking waveguides from i.materialize.
They are Polyamide (SLS) & Spray painted blackThose look really tidy. SLS with a black finish or something else?

As you can see, its totally our of control after 4k so the cross is 1.8k max to hammer that down.
I will start a new thread for this.
Oh you sneaky SB ..., ah stupid me. I forgot the Satori Textreme cone exists. Also because of it's pronounced cone break-up I didn't pay too much attention to them. BTW, how does the Textreme sound comparing to Alu cone SBs in terms of character/colorations? I wish there was Satori version of the Alu NBAC line - excellent woofers IMO.Funnily enough, its a Satori 7.5”. I get a much worse 5k breakup than any of the published measurements.

Those will be nice - especially with DSP. However if it were me, I'd go narrow baffle for the mid/tweet. Sure, wouldn't look as good, but IMO the baffle needs to be as close as possible to those high frequency units when using the waveguide.Good work! Impressive.
There are popular elements. Even that waveguide is apparently used by more and more DIY people. Here is Samuels, the same tweeter with the same waveguide, same midrange element and a bass element in a three-way construction. Bass in his case, Satori WO24P-4. I have listened to them, at the Vintage DIY fair I was at in November last year. They sounded really good. So those elements have potentntial, which of course you know yourself.

Hifi Vintage DIY fair with pictures
I visited this fair yesterday! DIY & Vintage meeting in Mölnlycke Here is a short report. When: 6 November 2021 Where: Country: Sweden City: Gothenburg I took pictures myself BUT most were so damn blurred so I borrow pictures from this thread, taken by other participants. Pictures taken from...audiosciencereview.com
Samuel has his own construction thread about them with various thoughts and measurements. If you can translate automatically from Swedish, if you are interested. I suspect you will recognize yourself in a lot of thinking regarding the elements, crossovers, placement of elements and so on.Many pictures in his thread. From page 4.
Hm, does it apply all the time or do you think you experience it every now and then?Getting back on the M105 copies;
After living with the M105 'copies' there is something that bugs me - it's like a sheen/glare over the entire midrange.
