This is taken closer up and is pretty close to colour

Drivers in the array are 10 x Vifa P11Wh + Vifa DX25 tweeter with simple 1st order series x-o at 3K. This is driven by the Dynaco MkIV tube amps. Pre amp is Bryston 1B, Tascam CD or Thorens TT with Audiotechnica cartridge.
Bass drivers are Jaycar 12" Carbon Response, crossed in stereo with active x-o at 90Hz driven by an old Marantz sand amp.

These are just sooooo listenable at low volume, precise, delicate etc etc, but can of course crank like crazy if required. Mids are just divine !!!
