My Pair arrived yesterday. It took me about 2 1/2 hours to assemble them. The quality of the cabinets and parts are excellent.
I just went with the Walnut and basic crossover. I have them on my Partington Super Dreadnought speaker stands about 30cm from the back wall.
Wow! It sounds like an LS3/5A with cajones. Just what I was after. Seems to match really well with my Marantz PM5005 amp which uses current feedback which helps to drive difficult speakers.

I've ordered a 1969 Hood 10 watt class A amp from China to see how it will work with them. I don't tend to listen
at loud volumes. These are the best speakers I've ever owned and knowing I put them together just adds a little bit of pride of ownership.

PS What a lovely guy Jerry at Falcon is, he couldn't have been more helpful.
