Thanks all for the warm welcome.
-Troels Gravensen... there is a bit of a barrier to entry with his designs: the woodwork tends to be complex and the crossovers are pricy. I’m reluctant to go along without having heard such a design, as the built cost is comparable to good used speakers, or even new ones, and resale values of diy products rarely meet costs.
-I will aim to demo some wharfedales but I’m surprised that this speaker works for you in such a modestly sized room.
-Electrostats - I have thought of those but never heard them. Must audition. The size of most models puts me off though. Do electrostats wear/decay over time? I mean, those quads are not exactly new...
