I had to try these from DIY HiFi Supply..I installed them @ 10,000 with just a 2.uf cap & no padding. A Coral fe103a & Vifa M26wr ran active for bottom support , 1 per side..At the moment I really like & can't find anything that jumps at me to say adjust or pull it. been 10hrs of music...so judgment is still out, but it is very easy on ears,,I will have to seem if image is negated, but should be o.k...for 45.00 a pop they seem to be a very good deal.. very well made & don't smell cheapness .. I will play further with them for sure..The high $ ribbons are out of my reach for a while , but this will give me an idea of what the better ones can do.
