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

I've had both brands for high-end two-channel systems.
I ***STRONGLY*** suggest you go with REL!
Believe me, in the long run, you will be much happier.

Lak,

You did not tell me why you feel this way?

More thought and technology put into the REL yielding better sound.
Check out the explanations provided by REL on Youtube, see the "REL Acoustics How To"
Talk to any store that carries both SUMIKO and REL and ask them their opinion.
In addition to the above, the REL customer service is there 100% to assist if needed.

Hi Lak, may I ask what REL model are you using?
Hello AudioConnection, a Vandersteen 2W can be had for $350 cash, locally. Where’d it stand in performance as today’s standard, Are the 2w-Q and Sub-3 much more superior than the original 2w?

REL T/5i, REL T/9i, SUMIKO S.5, and S.10
