I had a tri-wire setup with the HDLs. While they do affect all frequencies, I found the most noticeable (and measurable) improvement was in the high frequencies, so I agree with Rush, I would start with the tweeter.
Walker HDL in bi-wiring set up. Woofer or tweeter?
Proac Reference 8 Signatures bi-wired powered by Cary CAD 300 SE, through Speltz's zero boxes set at 1.4X (impedance at around 11 ohm nominal). IF I want to insert Walker's HDL, should I do it at the tweeter or mid-woofer? I know I should use 2 sets for bi-wired speakers, but just want to try 1 set first. Thanks in advance.
