Dahlquist DQ-20 Crossover Coil Upgrade Kit made by Regnar. This crossover coil upgrade kit is brand new, never been installed, still in the original packaging.
Regnar is known for their upgrade kits for the Dahlquist loudspeakers, and this crossover coil kit, which contains all eight coils, enough to upgrade a PAIR of DQ-20s, is said to improve the detail and imaging, and to increase the efficiency of the already great DQ-20.
Brand new, in the box and original plastic wrapping, with detailed instructions, this is priced by Regnar at $143.73 plus shipping. I don't need it, as all my speakers are the DQ-10s, so here's your chance to get it at a fraction of the new price.
I have it graded at 10/10 rather than new, only because the box WAS opened in order to get photos!
