ReL Subs: High Level or Low Level connection

There are advantages to both.  Low level with a high pass filter to your mains allows the sub to do all the work at low frequencies and takes some burden off your mains.  High level allows for easier integration imo.  I used the high level speakon connectors for my two RELs and haven’t looked back.  There are many around here who swear by low level and a filter.  I’ve not tried it but I’m extremely happy with the sound and integration I’m currently getting so I likely never will.

You likely already know this, but I forgot to say that the crossover setting on the sub is critical to getting it integrated.  Obviously it’s speaker dependent but I started with mine too low.  

@thebingster I have both subs set somewhere around 60hz. I had them set too low previously and could hear the transition between my mains and the subs. I have stand mounts so that might make the transition more obvious when it’s not right but I could clearly hear it. I tuned it by ear by raising the crossover until the transition was smooth and seamless. What the correct crossover point for you is really speaker and room dependent so start somewhere just above the lowest frequency your speakers are rated and work your way up until the integration works for your ears.
