Well, some progress 
Good and not so…
Had a great tidy-up and sort out in the workshop in the past two-weeks, loads more room now to actually make stuff!

And also just picked up a Makita LXT Router, as I have a few other LXT products. Its a great little thing, made up a quick circle cutter out of mdf which worked OK, although I need to refine it a little as its a bit rough.
The new Supravox 165-2000 AlNiCo drivers arrived as well, the Good is they are well matched, the bad is the Qe is well out of spec meaning the Qts is around 1.2 rather than around 0.7.
Initial impressions are Build is very ‘Solid’ if a bit rough around the edges, I know Supravox are a small artisan company in France but for the price I would expect the finish on the chassis to be a little more smooth, or less agricultural
