I have begun the build, but only as far as marking out the main baffle. I also have a pair of U-frames, as yet unused, from an uncompleted NaO II build. I'll be using the Peerless XLS 10s (830452) I already have, rather than the newer XXLS drivers (835016) specified for the Note- although as you know, there is support for that option in the plans, depending how the AXO is populated. I have yet to purchase the ER18s. The main panels will be a lamination of 12mm Panzerholz and 6mm birch ply, the latter is still to be acquired.
Rather than drag the OPs thread off track, perhaps you could start a build thread? I'm intending to, but my track record of documenting builds is not good!
