ReL Subs: High Level or Low Level connection


Good morning,

I have Rel S510 x2 in my system

Currently using Hi Level connection to my Pass Labs Int-60.

Had a conversation with a learned individual who feels very strongly that I should be using Low Level instead. Just Get the sun out of where the speakers are connected to the Amp

Any thoughts out there?

Thank you

Hi again @veerossi.  I would get them again, it makes me feel better!  And due to the long run the larger wire is probably a good idea.  I have some extra ones if you are interested pm me!

I have researched the high level option for driving subwoofers and according to Paul McGowen there is virtually no impact on the performance on the amplifiers when driving the subwoofer's high level inputs.  According to him the impedance of the high level inputs to the sub are so high that there is no impact on the performance of the amp.

I have a pair of T/i subs in my two channel system. I have both connections laid out depending on amp. Yes, the RCA's are a long run (purchased new from SVS..excellent people to deal with) but IMO based on my system and ears I prefer the low level connection. I feel it gives you more "head room" to make adjustments on the rear and allows the subs to do what they're suppose to do.

Appreciate all the input

Sounds like a HiFi debate

Equal numbers on both sides of the issue

I just compared using Hi level vs low level

At a given amp level and the same music the high level is 1-2 db higher than when using low level using my Pass Labs INT-60

High level sounds a bit better to my ears.

I'm a little disappointed as I was hoping to sell these baseline blues
