Vad sägs om den sida och högtalare Någon som lyssnat på någon av modellerna
Jag har bara hört ett par högtalare som jag inte minns hur de såg ut och hette, men det lät bra.

Han har i mina ögon ett märkligt förhållande till olika dyra och esoteriska filterkomponenter, samt både vettiga och skumma synsätt.
LeifB hade lite kontakt med honom som han kort beskrev här viewtopic.php?f=3&t=72656&start=240#p2225495.
Jag har i tråden 1: Frekvensgång, 2: Spridning, .. Spinorama? provbyggt lite slarvigt SB61NAC och var inte nöjd med uppmätt frekvensgång.
Jag delar dina intryck här: viewtopic.php?f=17&t=71880#p2172123
Annars har DIY mycket stor potential till gott pris/prestanda.

Don't limit yourself to TG designs. While he obviously has a good reputation, he doesn't show he's following the modern developments in loudspeaker design: he doesn't publish off-axis measurements or sound power analysis. And my eyes tell me his designs more often than not neglect the importance of directivity. He seems to be lagging some 10 years or more in design development
No it is not considered exemplary by all speaker DIY folk. He is something of a "subjectivist" and a hobbyist in the sense of swiftly trying all sorts of things that catch his interest to see how they turn out. As a DIYer gains technical knowledge and understanding their view of many of his designs is likely to shift towards too much money allocated to expensive drivers and crossover components for the overall performance achieved. He also builds his speakers in particular ways that aren't always that well aligned with the technical optimum. Nonetheless his designs are always competent which cannot be said of all DIY speaker designers even some of the more popular ones. His designs can probably be viewed as a safe option for those new to the hobby but they aren't necessarily going to be optimum in terms of technical performance for the money
I think the criticism is perhaps becoming a bit unbalanced. Troels is broadly an enthusiastic subjective hobbyist when it comes to speaker design. His designs tend to be less than optimum in terms of engineering but they are not seriously flawed at least not in ways that I can see. They often include overly expensive and at times boutique parts but that is part of the hobby for many and particularly those with a subjective leaning.
For a first DIY speaker project following one of Troels' designs seems to me a reasonable place to start
