In pursuit of aural nirvana, Niels decided to take a shot at the QUATTRO construction, but rather than building the vented version, Niels decided to try out a transmission line cabinet. The QUATTRO design fits well into this concept without changes to the crossover.
Cabinet construction details can be downloaded here.
As can be seen from the photos, Niels had some weird companions during the construction process...

Niels came by to have his speakers checked and indeed we have a matched pair:

Left: SPL from two speakers @ 1 meter, 2.8 volts. Right: Tweeter response from R1011 being 4R7, 5R6 and 6R8 respectively.
