I need a subwoofer/sub-bass opinion from you

Hello All--

I have a large room (well large to me).  It's 20' long, 15 wide, and 10' tall.  I run either Klipsch Forte IIIs or PSB Imagine T2s through a tube amp.  I have plenty of volume with either loudspeaker.  

What I want to accomplish is to add sub bass.  I did this previously in a smaller room with a Sumiko S5 (I believe it's the same or similar to the REL T5).    When I had the Sumiko dialed in, the system congealed into a wonderful sound.  There was no noticeably appreciable sound coming from the sub.  Instead, it merely filled out the lowest octave and added space, dynamics, and really made the highs seem less harsh.  

The Sumiko S5 does help in this setup but it's just not enough to charge the room or at least add enough.  

I'm thinking REL.  Thoughts? 

PS  When I ran the Sumiko, it sounded clearly better when I ran it off the amp speaker outs than off my Primaluna's dedicated subwoofer out.

It will soon be 2019 and you're considering flip phone subs.

Subwoofers with room correction that are adjustable from your listening position have become affordable. 

Every subwoofer suggested here can do the job, but how easily and how well they can be integrated to your system and your room is questionable. Compare their setup procedures then look at the procedures here.

@m-db have you listened to Syzygy subs?

Wrt flip phones the SVS SB-3000 does appear to offer from-your-butt control via Android/iOS app. At a glance the control doesn’t look as refined as Syzygy’s.

Whether those or Velodyne units and their integrated DRC systems perform at or above the levels of comparable "flip phones" should also be questionable. REL, Rythmik, SVS, HSU and PSA all still seem to be in business, developing/improving and supporting their products within constraints of those businesses, and from feedback here and elsewhere seem to have their shares of discerning owners.

Yes I’d prefer to integrate subs into my 2ch rig from the comfort and optimal location of my butt. But I wouldn’t weigh that feature inordinately above overall sonic performance, reliability/service* and fair value. For now I’m fine with some manual monkeying.

One thing to keep in mind is there are two types of subwoofers. One is made to gel with your system and the other is to go low.

In most rooms once you work with 250hz and below you will have two different sets of pressure zones that react differently depending on your room's material and construction. If you have basic stud and drywall construction with wood floor joist you will get more musical tones to work with. If you have plaster walls or double drywall or quiet rock and a basement, you might end up needing two sub designs.

I have found that almost all newer high end audio main speaker designs end up wanting a sub to complete the range.

wrt 'flip phone' subs, nvm: after a lightening research session this morning, I bought two Syzygy SLF870's.

Will report back with observations & field test results.  In meantime here's a favorable review that helped tip my decision: http://forums.stevehoffman.tv/threads/syzygy-sub-woofers.682718/

REL subs with the wireless transmitter seem to work the same way sort of...and it's all good. REL should make a retro fitted "longbow" gizmo for people like me with older models, but do they? NO THEY DO NOT. I gotta calm down...whew...
