I've had a pair of REL S510 for two years that I use for both my HT set up and my 2-channel system. I'm a huge fan of REL -- I like that you're able to have HT and 2-channel connected at the same time each with their own adjustment. With my systems, the sound is spectacular. Like you, I debated between the S510 and and S812 and while I have no doubt the latter is even better than the 510, I determined that the smaller one was more than sufficient for my room size and system -- and that was a good value decision. The only other thing I'd say -- they're an incredible addition to a 2-channel system and if you can swing it, buy two of them. It really adds to the soundstage depth and breadth. Good luck.
REL S510 or S812
Hello all
Im buying a new sub. Ive narrowed my search down to REL. My budget is enough for a new S510 or used S812. My system is dual purpose so Sub has to be good at HT and 2 channel. Thats why ive landed on REL. Im not a fan of buying used because of warranty consideration mainly, but if the 812 is considerably better than the 510 I would consider. Does anyone have first hand experience with these subs?
