ReL Subs: High Level or Low Level connection

Mijostyn

Thank you for all that info.

Some a bit over my head.

Does what you say apply to SUBS with an amp in them ?

For instance my Rel S/510's?

Or just to passive subs?

Thank you

I like to run my mains full range, never with any type of high pass going to my Amp.  With a low crossover the REL will never call attention to itself. 

Does that mean you are running 'low level"'?

No, running mains full range and driving sub via speakon cn.   I have a Velodyne SMS 1 that I used to use with the REL but I took it out and went speaker level off the same binding posts as speakers.   I ran that RCA and single cable out of that to sub.   I set the crossover low, at around 40 Hz.  Never calls attention to itself 

The 40 step  X - over knob on a REL  that is marked 25 Hz to 100 Hz is about 1.8 dB per step.

Please share your thoughts/ experience with the upgrade to the bass line blue cable. I'm running 2x S/510's with class D monoblocks (1 connected to each amp). I upgraded power cables to Shunyata and that made a noticeable difference in sound quality. I also bought some speakon connectors and was thinking about making my own version of the blueline cables but with some better quality wires.

Hi @veerossi

i found the Baseline Blue cables to be fine for sub high level connections.  I have nice cables everywhere, but do find the sub cables the least impactful.  I certainly looked at other options, but I have one long run of 30’ under the floor and across the room, and never felt the need to upgrade more. I am sure you can make better cables with nice copper wire.  Understand your connections first as you may likely only need two wires vs the three in a REL wire.
