ReL Subs: High Level or Low Level connection

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.

My Rel 812's work quite well with the Audion Mk3's using the high level connections. The Audions let me evaluate sub settings more accurately than did my tube amps.

Thanks for this info @fastfreight. I concur: sub cables are the least impactful. Yes, I’m using only 2 wires on each sub. Using all 3 was far too much.

If you could go back, would you spend the money on the Baseline Blue again?
