Quad ESL 57 with subwoofer

@georgehifi Nice but they don't have high-level inputs which won't work for me.

Thanks guys. I ended up removing the old REL and adding it to the other rig. It burned out anyway and I replaced it with an S3 which is MUCH better. The Quads sounded better without it. I've also removed the grills.
I was thinking of something like a pair of REL T5i.

I got a REL Strata 3 and it works well. I adjust it depending on recordings but for the most part keep it subtle. Definitely adds something to the Quads. I hope to buy a second one.

Thanks Dynalead. So are you running them from the same amp in parallel with the ESLs? I was thinking of powered sub(s) using a high impedance input from the speaker terminals...

Thanks all. Good stuff.
