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

My update,
I bought a REL T/7 and it is very good, very tuneful for my 2-ch listening. It’s nicely adding to the lows, and like many others had mentioned, it’s def not shaking the house and that what I was looking for.

Saw great potential of the T/7 and quickly bought the S/3. Wow, love it.

Note: If you are looking for a sub that will play (much) louder than your speakers, REL will disappoint you, horribly.

Thank you AudioConnection for tips on Vandersteen 2W Sub but, for now, I decided to go with RELs for easy/quick plug & play connection instead of spending more time researching on what to do with that Vandersteen Sub's X-over network.

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.
