For a value priced speaker cable check out Kimber 8xx or 4xx many bi-wire with 8xx going to the mid-woofer and 4xx going to the tweeter. I used a long(36 foot pair) of Kimber 8TC for a long time and it sounded pretty good for the money, plus it is super easy to sell kimber and either break even or make money(as long as you buy used to begin with). You could also use a single run of 8TC or something similar and split it into 2-4TC runs while retaining the original braid.
