Good replacement 5 stars 5 out of 5

Chosen to replace failing Audax drivers in a 20 year old home built system. Crossing over to Titanium tweeters at 3K5 the slightly lower efficiency seems to be a better match than the originals. The drivers will need further running in, but I can hear improvements in the depth and attack on bass notes while the mid-range is clear and stable. I did have to upgrade my speaker stands to take the extra weight.
I am happy with my choice.
