Further Information: 

These were bought with the other drivers and Jantzen crossover kit, to build Troels Gravesen's SBA 3-way Classic speaker:

This is an excellent low-budget design from the master, and I was going to use them in my system, which morphed into something much larger (mains are now 4-ways, weighing 140 kg each).

Being my irreverent self, I departed from Troels' design, using a pyramid box and started changing the drivers and crossover etc, so these have been sitting in their boxes since 2016, unused.

This can hopefully save somebody a few dollars in building this kit, or some other design. There's been a slight model change, but these are still first on Troels' page. For reference, the new ones are available at Wagneronline:

Condition-wise these present as new, but obviously had screws fitted and wires soldered. There is no cosmetic damage or overheated terminals, etc. They have a lot of cool features, as in the datasheet:

Packaging is original (good), and this will be improved further if they need posting.
