Dear all, anyone have any insight on this one: I plan to bi-amp my centre speaker. My centre (Kef) crosses over to the bass drivers @ 400Hz. My question is, is it okay to use different types of cable to the bass, and to the mid/treble? In this particular example, the mid/treble is getting 14AWG silver, and the bass is getting 9AWG copper. I'm slightly worried that the higher resistance of the copper will cause a volume decrease on the <400Hz, detracting from the neutrality of the speaker and consequently the 'rightness' of the vocals. No 'try it and see' replies please, as the decision is motivated by the desire to save $200 on the other leg of silver cable... Cheers!
