Like Unsound said, be careful with midranges. I owned a pair of 3.5s and probably went through 4 midranges. The problem is that they use a first order crossover, that while yielding excellent phase linearity, burdens the midrange with having to deal with significant mid/upper bass energy due to the shallow slopes. Thiel was extremely helpful with providing replacement units, even after the speaker was out of warranty.
Thiel 3.5 equalizer advice
I am using Thiel 3.5 speakers without the equalizer. Does anyone have any insights (or firsthand experience) on the overall difference in sound that results if I bought and added one to my system. Does it just impact bass response or will it impact other sound qualities? Does Thiel still make the equalizers? Thanks for any insights.
