I have at least 4 or 5 pairs of Diamond Audio Hex and 1 pair of M series passives that are collecting dust and will never get used.... I only run active set ups these days and would like to unload these things... Make me a reasonable offer and they are yours for keeps... They are used and some have some left over dynamat smudges but can be very easily cleaned up and all work great. I am just not a big fan of passive crossovers...
