which is more musical? A REL or a SUMIKO subwoofer for two channel only?

update...Went with two G2's from REL to go with my Tidal Akira's and after the "fine tuning" process I am in ABSOLUTE heaven!"...:-)

Excellent choice....when it comes to music, REL is the way to go! 

Congrats on the G2's!

I was turned on to RELs some years ago by a close friend, and immediately found a used Q150e (150 watt front firing 10") on Ebay for 200 bucks...perfect but needed a new grill cloth (had the frame, easy fix)...GREAT sub that seriously transformed music in my Hacienda. A couple of years later added a Q108MKII (100 watts 8" downfiring) also for 200 bucks and that's that...seriously well made subs, great sound making me a "more than one sub" for home audio believer.

Happy with my REL S3 SHO. Saving for a second one. Used, as they are replaced by the new S series which is a little more expensive. Very fast and tight when needed. You might look into 4 smaller ones like the t7 as an option.
