I already have 2 of the RF-82 woofers in my RC-7, so I was able to use those to verify the fit, so no need to use a picture. Nowhere did I say the DCR of the RF-82 and RF-83 woofers was the same because it’s not…it was mentioned by the OP in the first post of this thread that the RF-83 uses 3 16 ohm woofers(which aren’t available anywhere) wired in parallel which would achieve an impedance of 5.33 ohms. Wiring 3 of the RF-82 8 ohm woofers in series/ parallel will also work out to 5.33 ohms, which should work well to replace the original woofers as there is no other(new)option to replace them.
