Subwoofer insight.

Actually, the SVS 16s that you recommend start at $2000 each.  The question from OP wasn't about which sub to choose.  It was how to make the best use of RELs, which he bought.  That said, the T/7i that he bought currently retails at $900.  

Bringing the discussion back to OP, in my experience, the RELs are good for stereo.  I'm happy with mine, and honestly think that since adding dual REL subs, by system is better balanced at all FR and sounds better than it ever has.  We'd like to hear what you think after you get it all tuned in.

I will also say I"m a big fan of SVS.  My father asked me to help with his HT setup, and we got him a full set of SVS Ultra speakers and a pair of SVS 2000 subwoofers.  His system sounds fantastic, too.  For HT.

• Sorry to the OP and I won't respond again. 

I don’t listen to any music that has bass any where near 20hz, let alone below 20hz. "I just know the RELs are twice the money of the SVS subs while getting less." You make your statement as fact, but it’s your opinion. I don’t want to defend REL, because I don’t have a financial interest in them. I submit "we" do a disservice to the audiophile community when we make comments like, "I just know the RELs are twice the money of the SVS subs while getting less." The truth is they’re different and to my ears, SVS just don’t produce different shades of bass. If someone said they required a subwoofer for HT and didn’t want to spend a lot of money I would recommend SVS. If someone said, they want a subwoofer that produces different shades of bass for 2-channel , that improves everything across the audio spectrum, I would recommend REL. If I had to recommend a subwoofer to someone with a dual purpose system combining HT with 2-channel and price isn’t a concern I recommend JL Audio.

My only reason for not buying a REL speaker is they don't dive deep enough. Notice I said speaker not sub....My SVS SB2000 can reach below 20Hz, has nothing to do about "hearing" this, its about feel and sustain of musical passages with deep notes.
My main speakers are prolly in the 35Hz range, why get a REL that is at 30Hz range, and pay 30-40% more.

Super pleased at what the SVS does to my 2-channel.....Proper setup is critical.

It only took this OP a couple of days before he quickly realized the undeniable shortcoming of old school set-it and forget-it subwoofers. Smart guy. 

I don’t listen to any music that has bass any where near 20hz, let alone below 20hz.

These low frequencies are inherent in the acoustic resonance of large spaces. Therefore present in all music that is well recorded in a large space. Its not "music" in the sense of any particular instrument playing it. Although this is definitely the case with a lot of music. But it is also there in a surprisingly large number of recordings of all kinds of music.

In other words its not that its not in the music you're listening to. Rest assured it is. Its just that your system is unable to reproduce it. If it were, you would experience it. Specifically, you would experience it as a heightened sense of envelopment, of being in the recording space, as opposed to merely being in your room. No doubt about it. Read the comments.
