Nice Polk RTA 12B crossovers

geppy1 · September 2013

Here is a nice pair of RTA 12B crossovers. These were used 1981 to late 1983. They stayed the same for early 12Cs but sued different brands of caps. If you have early RTA 12s you could use these as an upgrade and you would haver the outside driver roll off as it does in the Bs and Cs Makes a big difference in imaging. The early one used 6500s and the Bs used 6600s but they cover the same frequency range so it would work very well. Includes tweeter holders Asking $40 thanks
