If you ever find a pr. of thr Clements speakers with the ribbon tweeter that was mentioned at the Clements website and in the previous post, BUY them. At this time , if you ever find a pr. which I highly doubt you'll find, they can be had for a song. Like 10-15% of their retail price.
I have in the past owned 6 or 7 prs. of speakers most of the time. As you get older you find certain speakers that you just can't let go of. My favorite speaker for many, many reasons are the Apogee Stages.I've never heard music produced the way they do. Anyway, when I have friends over the Stages are off limits to everyone,they are disconnected. The only speaker I've owned that will never leave me are a pr. of Clements RT7's and their sibling the Little Wood 'D'. I've never heard the mass produced speakers you asked about, but, if Phil Clements is the man at the helm of Solus/Clements there's a very good chance his speakers are overacheivers and the price's may very well not be indicative of the value.
I look forward with great anticipation to Clements speakers using the ribbon tweeters that are pretty good out to apprx. 40k hertz.
