Mike23:The xlr cables I have retail for about £300, I cannot remember what brand they are... sounds stupid but I have bought them used from a HiFi dealer about 2 years ago, and he recommended them... I am wondering if it is worth to spend extra money on a good subwoofer cable, or if any cable (as suggested by someone) would do...
I use a (freebie) grey and black cable of about 3m long connected to one of my amps preouts... It works wonderfully, and I think actually better than the official MJA high level lead I used to use on my old amp. (cant do that on my class D for some reason)
I don't believe you'll be able to tell the difference in any cable up to the job, when it comes to a sub bass speaker.
