Hi,I'm getting on, but I never heard the original version. It sounds like these will potentially give studio monitor accuracy and detail etc. I'm not sure they are worth 3 and a half grand, even with the stands and gloves, but I bet they sound superb, in the right conditions. I suspect every part is brand new and not using parts, from current bins etc. The tooling and production costs, must be high, for a new range and of course, UK made, will cost more than made in China. I'd buy a pair, if I had a larger room and deeper pockets. Way out of my price bracket.
I designed my own transmission line speakers. I used freeCAD (Linux) to generate the design drawings, sent off to the woodworks for CNC MDF cutting, costing £250 including the MDF (25mm). The drivers (3 way) and the CNC cut MDF cost £1,030 in total.
I have seen a forum post (PFM) where someone was rather angry that their PMC speakers costing in excess of £2k had £25 tweeters (reportedly).
If you have some skill in gluing, then it is quite easy to create your own speakers, where the cost is vastly lower than commercial. As such, you could obtain such speakers for a fraction of the commercial cost.
