Has Rel fallen out of favor with audiophiles?


I own a Rel Storm 3. which I've had for 10 yrs or so. My new hardwood floor has really opened things up, especially in the bass area. much more pronounced bass and excellent sound stage.  I was planning on upgrading my sub after completing the floor. My Rel Storm 3 is pushing at its max to keep up in a 5k+ cu ft  room. Ten yrs ago the Storm 3 was one of the best on the market. It integrates very wall into the 2 channel system. Now, there is SVS, Rhythmic, PSA  etc which have much better specs than the Rels for less $$$. But the question for me is whether they actually integrate with the main speakers as well as the Rel? I use mine  for music 95% of the time. Music doesn't need to plumb the 16hz range as much as HT does. And most of the reviews seem to come from HT sources, IE AVS forum and the various HT magazines. From what I can tell, then Rhythmic seems to cater to the audiophile more than HT. But how about a sealed  SVS ?. And will they both integrate as well as the Rel with the high level speakon input? 

So, for audipophiles, do you sacrifice the ultra low hz for the good integration of the Rel? Or do you go with then SVS, Rhythmic, etc with their lower octave output? IOW, do the integrate as well?
Thanks for your help

To answer your original question in your opening, a resounding YES, I would NEVER EVER sacrifice integration/coherence not to mention the benefits of a meatier more real midrange, greater image and soundstage accuracy and more natural presentation, for the sake of ultra low hz? yeah maybe if you're a headbanger or maximum low frequency SPL's are the goal, different strokes and musical tastes would dictate. 
artemus_5,

"My only question is whether a kit will be cheaper? IOW, if you count your labor as worth something, can you really save any $$$ over a comparable production Rythmik sub?"

Well, that depends on fit and finish and what you do and don't do yourself. I have a picture of my subs on my system page. I am not a carpenter, nor set up with a shop for that, so I farmed out the finnish work. Plus, I used Tineo (Apple Wood) veneer to match my main speakers for the cabinets and amp boxes. And, I had grill frames made, but will add my own grill cloth later. Parts and labor in the end came to about $4,200 for two subs. Then there's shipping.

I use 2 older RELs with Canare cables I put together. A Q150e and a Q108eII and they're perfect, and each cost around 200 bucks (used of course). I suggest a "swarm" system if you want an ultimate sub experience that's still musical, or do what I did and get another REL…the RELs don't have the alleged distortion at low levels that others have claimed, and although I can't speak for the new stuff (well regarded anyway), the ones I've owned for years are built to last…just tighten the speaker screws from time to time.
I have an REL S5 and would not trade it for anything. It does everything i, prior to buying it, that i wanted and then some. I great product.

artemus, for clarification here's some additional info: Rythmik Audio and GR Research have a unique working relationship and marketing arrangement. Brian Ding and Danny Richie are both located in Texas, and pooled their talents to design some of their products.

Brian Ding of Rythmik is the designer (and Patent holder) of his Direct Servo-Feedback circuit, which is included in all versions of his plate amps. He also designed and builds all the Rythmik factory-finished sealed and ported subs, also designing and having built his aluminum-coned woofers (as well as the paper-coned woofers found in his budget subs).

Danny Richie of GR Research is a speaker designer, focusing on drivers and x-overs for open baffle loudspeakers, for the DIY speaker builder. He offers kits only, no finished loudspeakers in cabinets, though he does have a few guys making enclosures for GR Research customers, built to Danny's specs. Danny is responsible for the paper-coned 12" woofer offered in the Rythmik F12G (he prefers the sound of a paper cone, and feels his provides low-level resolution and musical timbre superior to the aluminum version), the non-G version having an aluminum woofer.

Brian and Danny both sell the Rythmik DIY sub kits, while Brian is the marketer for the finished subs. The sub flat pack enclosures offered by both DIY Sound Group and Parts Express are one and the same, PE buying them from DSG, marking them up a little, and reselling them. There is both a 3cu.ft version and a 4cu.ft. one, the larger intended for 18" woofers, but recommended for the Rythmik 15" woofer as well.

The DIY Sound Group flat pack enclosure is an okay design, but could be better. Adding more internal bracing is a real good idea (Jim Salk's enclosures for the Rythmik subs are absolutely incredible!), as is adding a second layer of MDF to the single 3/4" panels, which are barely sufficient. I designed my own 4cu.ft. double-walled sealed enclosure, drawing up the plans and having a flat pack cut by a cabinet maker in my locale. Assembly with wood glue and braces is not too difficult, and the MDF can be veneered or painted in any way one wishes. I chose "Hot Rod Black" by John Deere, intended for their farm tractors. Looks real cool, like a 50's custom car---not glossy, not flat, more of an eggshell type low sheen. No flames, though!
