OK, I ran it through Photoshop. "The TCN of Acoustic Fidelity."
Everything about this screams white van, except the actual speakers! A crossover that has clearly been designed with some degree of care, lots of numbers on the back that are actually relevant, weighty drivers, heavy cabinets...
How strange. The crossover is dated 7/1/2005, which means they're not that old.
I cannot find anything online about "TCN" or "Acoustic Fidelity" or "Series.9" or any combination thereof... and my Google Fu is strong. I am very interested in where these came from.
