Captive speaker cables

[VantheMan]

As I have made up my external crossovers as suggested inside cigar boxes, I am thinking of connecting them direct to my boxes without resorting to bananas or spades anywhere, in other words I´m going to use captive cables between boxes and Xovers. Is there an accepted, neat way of exitting the boxes or should I be looking for some kind of grommet to accomodate the cables woofer/tweeter cables and thence to the cigar boxes ? Any ideas ?
Thanks in advance
Chris
