Hi there, I'm new to the forum, and French so all apologies if my English is not perfect.
Well, I'm thinking about building a pair of Zaph's SR71 in a 18L cabinet, but switching the TDFC tweeter for the higher range TDFC/G (aluminum) or even for the Excel Millenium one (T28CF002). It seems they share similar characteristics to the TDFC.
The millenium got very good reviews everywhere, and seems to perform better than the TDFC in every point except for the sensitivity (89dB/W vs. 90 dB/W) but apparently it can easily be compensated by lowering the corresponding resistor on the tweeter x-over section. Especially, the millenium has a much better off-axis response. The TDFC/G doesn't have the bump at the end of the response curve, although it has a big one around 26kHz: would you think that bump at high frequencies might be responsible for listening fatigue? It has a big advantage over the TDFC: its hexagrid protecting the tweeter from the too curious small fingers...
It would be my first DIY loudspeaker kit, my initial budget was more around 1000$, but I was hooked when I read reviews of the SR71 and when I watched a video on utube comparing them to the Bifrost (surprisingly I liked the SR71 better, they sound more organic).
What do you think about it?
