Seems like every thread becomes contentious anymore. If you don' like the word "Rel": in the title, then instead of seeing red and getting you panties in a wad why not look at it this way

How does a REL subwoofer add dimensionality and depth to a sound system?

The video is put out by REL. Do you REALLY expect them NOT to put their name on it?

I get it. You like the flavor of the month. It's Rythmik now. It was SVS previous. Before that Rel. And as has been pointed out, when I bought my 1st REL neither of these brands were in existence. The point that I got out of watching this video is that the bass itself is the very thing that makes the dimensionality and  depth. So IF that is the case then the bass of the Rythmik & SVS are also instrumental in this task

@oldhvymec I understand that you are knowledgabe. but how many times do you need to hear that the REL subs are NOT DESIGNED TO DECOUPLE NOW DON'T THOSE CHICKENS NEED TO BE FED? And LET THE DOG CHASE THAT RABBIT FOR A WHILE. hE NEED THE EXERCISE.(sorry. Didn't mean to holler...stupid caps lock)

" But I’ve often wondered how my Rel subs make such an improvement to the main speakers."

doesnt he say how in the video ?

what was the point of starting a post if the answer is mentioned in the video

OK, So I got this in my messages from the above. Can someone tell him what the function of this board is?

I’ve been here 20 yrs now and have never had anyone email me something like this. Funny thing is , he too has been here 20 yrs and doesn’t seem to understand why it exists. As someone said earlier, this place has gone downhill quickly. I could understand this from a newbie. I’ve learned to expect most anything. Oh well. Let the games continue
