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

I love my REL. That said, when I wanted to get additional subs, I went with Rythmik. Why? REL is limited in the controls it offers to completely dial it in. For example, the phase is either 0 or 180; Rythmiks have a phase dial which can range in between 0 and 180. There are also a number of other features on a Rythmik —not least, their servo approach in the sub design — which you can read about, here: http://www.rythmikaudio.com/F12SE_features.html

Here’s a photo of the back of my two Rythmiks. I’m not saying that other subs don’t have this, only that this is why I chose Rythmik over additional REL’s.

I will continue to enjoy my REL in conjunction with the Rythmiks. But I have learned how hard it is to make bass work in my room, and the lack of flexiblity on the REL sets them below my Rythmiks. Phase has been my key to making everything work perfectly in 0-300hz.

Wow, the OP’s original question was pretty quickly forgotten. I hope this does not turn out to be a thread for REL haters and owners, but some seem itchin’ for a fight.

I’m a bit like @hilde45 on subs these days. When I bought my Britannia B1 and Storm III it was years ago and most of these new subs either did not exist or were not known by anyone. REL was one of the most musical subs offered, period. My B1 with my mains was fantastic and tight, running very low bass only.

That said, the most recent three subs I bought were two SBS SB-2000s and one SB-3000 and all three sealed subs are now in my audio room. The B1 went into the home theater (with an old DefTech PF1500) and the Storm III audibly lights up the 14x18 ft TV room now.

I believe in the DBA concept now, but feel that poster missed the OP’s question as well, even though good points were made on why DBA works well. As for the rest, why not start an “REL sucks” thread and have your own fun.   :-)  

I agree with hilde45. I went with JL Fathoms over Rel. They offer much more flexibility in set up. They have full adjustable phase to adjust for proper placement. They also have built-in room correction via eq. Another point for me was that they are built in USA which makes service easier if it is needed for me. 

The whole high level input is over rated imo too. There are also more than a get folks that have damaged amps by not having the high level connected properly.
