Moving up in the REL line of subwoofers

@ronkent Nice setup! Have you tried moving subs away from next to speakers? Often that makes a big difference. If they are well spaced in/around the room, then often more dimensionality is a welcome outcome. Refection on your reflections is my predilection.

Add a touch more gain? Adjusted the crossover?  Roast beaf and popovers? 

The 212se was replaced by the newer/upgraded 212sx in 2022 I think - do not know the technical differences and yes, the cost was quite higher...also do not know the technical differences with the new, just introduced 212...

@ronkent well if you have done pragmatic room coupling of the subwoofers I don't think you would be having upgradeitis

The truth is i am very happy with the sound and have no complaints or issues.  I know however from being  deep into this hobby since i started in 1975,  that there is always room for improvement.  Don’t know how that would sound until i hear it and thus am always on the lookout for things i could do to improve the sound and the enjoyment factor.

@ronkent 

so Dwette,  you had good luck with the four pack and preferred it over the 212?  

I never had a 212, nor claimed to. But that would have just been bigger subs in the same room. A REL line array is a different animal. I didn’t need more bass, so the 212 wasn’t considered. I wanted better bass and better space (soundstage), and that’s what a REL line array accomplishes. The REL web site has several articles about the six-pack and line arrays. Might be worth your time to seek those out, before you go to the trouble to trade away your S/812s. They can form the foundation of a line array. The 212 subs cannot.

My four pack of S/510 worked great. Recently, I made it a six-pack and that’s amazing. I’m rediscovering a lot of my record collection now that I hear so much improved soundstage and ambience from recordings.
