Thiel CS5 modifications

@steffa2: I don't know if you are an audiophile or not, it doesn't care, you are welcome the next time to listen to these loudspeakers. I can ask the owner to set the cables as before the mods, to listen to the difference.

@Stringreen: only the owner can decide. As I said before no one with sane mind and body will ever spend 9.200$ for a pair of good loudspeakers like these and then let someone mess with the crossovers without care. No this isn't the case.
As for me, I listened to this pair of CS5 finding it very impressive with slight differences in the mid-bass region in comparison to the original one.
Their owner has chosen to keep them after all these years, instead of selling and pass to something else and I can agree with his decision.

...But being an electronic engineer and daily dealing with technical design issues I'd like to point out that in any product there are NO fixed rules. Any board or circuit could be improved or work even better thanks to some small changes. Since there are no test evidence posted here of what is better before and after the modification, my personal view is that we would need to listen to this product with and without modifications and then take a decision....

Welcome Steffa2 to this discussion, in our field common measurements as frequency response in anhecoic room, Mil & Mol as for the loudspeakers, mean little being only bi-dimensional graphs of what happens in three dimensions. So, as you say, we need to listen to judge.
Time and phase response are very important to reconstruct the real event in our rooms. Moreover our ears are very sensitive to phase change at high frequencies, but, if the the number of ways increases and the crossover becomes more and more complex, this reconstruction is very difficult to obtain.

Hi guys
...
But being an electronic engineer...
So Cheviot, thanks for pointing this out, I'm very interested to check wether this modification is really making difference...cheers guys

You could be the third valuable witness after Cheviot and the owner of these loudspeakers to the sound of these mods. An audiophile-engineer!

If the electronic engineer has the curiosity, he is welcome, can contact me anytime, I will ask the owner to organize a private listening session for him. Aloha!
