Amplifier power needed by 1.7s

I had one REL sub and after six months added another...it did make quite a substantial improvement in depth and ambiance retrieval. I've spent too much money over too many years on trying to make a silk purse out of a sow;s ear (attempting to make horrible recordings sound good on quality systems with expensive tubed gear). And don't let anyone tell you that Maggies do not need a sub!!

I heard the 1.7's with and without a rel sub. Addition of the sub made the 1.7 a much better speaker. I was very impressed. I'm not so sure that tube amps are the answer. I prefer SS with maggies. I'd go for tubes in the source or pre.

Somehow (in my first response) I missed that you already have a REL sub. Everything I've read (and heard 1st hand from an owner of 1.7s and a Rogue Cronus Magnum indicates that that is an excellent amp/speaker match. After that, add a second matching REL sub. Two subs blend easier and give you more options for smoothing out room node resonances.

My experience with twin subs matches Auralone's. I started with a single sub in November with my 2-channel system with Mirage speakers. Three weeks later I added a second. Adding the second one unexpectedly resulted in much more 3-dimensional imaging and more perceived space around the voices and instruments.

Thanks to all. Being new, I'm not sure of the etiquette but this might be a good point to wrap up this thread. Lots of good info. and thoughts. I now have an idea of where I'll go from here.
