Danny advises against tweeter changes, but I figured this was close enough, and it is a win.
ELAC BS41-BK's with upgraded crossovers, has similar looking soft dome tweeters to Danny's T26SG Tweeter.
Nice improvement. I am running Focus Fidelity software that can do corrections if needed.
I have not yet run the software tuning, but these T26SG Tweeter's are a very nice improvement over the ELAC BS41-BK originals.
Thank you, again Danny... even though your normal advice is to not do this.

PS. The recently installed SVS Ultra Bookshelf upgrade is a win.
The upgraded Carnegie CST-1's continue to bless my ears also.

Oh, I am sure that the T26SG tweeter is a huge upgrade. It is one of the best dome tweeters out there.

It will definitely have a different response though, and is probably a little louder as the sensitivity of that tweeter is pretty high.

If you like it though, that is all that matters.
