SPKR cable for 4x1200 amp @4r ?

Question : Is 2x2.5 twinax speaker cable ok with this amp, or would 2x4.0 be better, at least on the bass bins ? ( 4 box system 2x8 top/mids and 2x12 bass bins )

Thanks.

I have tried 4mm twinax on short 5-6 metre lengths on both tops and bins, and compared the sound with 2.5 twinax which is my standard cable. To my ears the 4mm definitely sounds better overall, but there is not a lot in it. I ,now, need some longer cables ( 10-12 m ) so ,maybe, the 4mm would be better on bass at these lengths ?
Any recommendations as to make of cable ?

Buy some gold connectors too that will help.

stop being mean you lot!!

if you can't find a bare ends cable just buy a speakon to Jack and cut the Jack off and throw it away!

Thanks Guys.

I have heard of people on here using 6mm cable, but that must be for higher power and longer lengths ....
As has been said, easier on the amp channels with the 4mm, but overkill for shortish lengths at this sort of power.......

Must say, I have just been 'playing with' an 800 watt guitar amp ( 2x400 /4r ) on recorded music with a small 4 box EV pa rig, with 4mm on bass and really cheap 1.5 mm on top/mids ( through the bass bin crossovers ), and it sounded great on low gain( I was in  the house at the time ). The dog next door complained loudly, though the sound was below registering on the signal meters! Lol

There are some online calculators you can use to work out losses, etc. for various cables runs. You also need to think about damping factor, especially for longer runs.


Here's a quick guide:
