Ahhh--Problem solved. Adding a REL sub-bass unit...


I'm wondering how many audiophiles have given up on loudspeakers preamturely, or have gone down the rabbit hole of cable swapping to "fix" an issue with their speakers.  

I grew up hating subwoofers and home theatre.  I still haven't come around fully to home theatre.  I've warmed up though.  I've had my own issues with otherwise great loudspeakers, including a pair of Klipsch Forte IIIs.  I was very frustrated as I'm feeding them from a respected tube integrated, I've tried them with a 300B amp, and I've toiled over positioning.  

The issue that I was having was the mids and highs were dominating in my room--despite the size of the woofer and passive radiator. Some recordings were just too bright.  Sometimes I felt the speaker, however "alive" and dynamic was not imaging well, needed soundstage help, and so on.  

I hate to say the REL T9i I threw in the mix today is a panacea because there's always stuff to tweak.  Yet I have experienced this before with a Sumiko subwoofer.  Adding one to the mix and dialing it in so that it's barely audible has brought everything into focus.  Everything is more relaxed and energetic at the same time.  

I'd say that the REL is a room tuning device above all.  I have a larger room (I think it's 15 wide, 24 long and 10 high--in feet).   I'm not sure how much I'd have to spend or what different choices would solve this otherwise.  From a guy that used to reject subwoofers out of hand (my bias came from the 90s home theatre craze) I think that they might be necessary in the lion's share of systems with the lion's share of speakers.  To say, "you don't need a sub" with speakers might be true depending on your room, but I also think in most situations you are missing out on what they can do for so many criteria that are not necessarily in keeping with adding bass--e.g. soundstage, focus, imagine, fullness, taming treble, etc.). 

Finally, I really wish that I could try some other brands as many audiogon members recommended so many respectable names.  I ultimately went with REL because of its philosophy, my similar experience with a Sumiko sub (within the family of REL or somehow related), and the high frequency input connections.

Does anyone who has a REL mind that pretty much all their initial lineup doesn't dig down to 20Hz? Even the S3 drops off significantly before 20Hz. Seems like a prerequisite if going to spend money on a sub....and it's the pretty much the one thing that prevents me from buying a T/9i. Convince me my fears aren't warranted....
@ieales What do you recommend for a single capacitor that is "plug N' Play"?
(that is minimal DIY)
Points taken, but since I have Vandersteen 2Cs and those already go down to the low 30Hz, would I still benefit from a sub that only goes down a few hertz lower?
" IMO, the point of a sub it to reduce the load on the main woofer"

RELs don't do it this way, they are designed to pick up where the mains drop off. Vandersteen Subs do this, however.
" That, my friend, is nonsense."

Well of course you can tweak your output and set the low pass frequency on the REL to get a good integration with the main, but no load is being taken off the mains (as far as the amp is concerned) using the high level connection - which I believe is how the RELs are meant to be set up. Mains will keep running per usual and the REL will fill in the low end (Am I right?) With regarding your original statement I would say if you are truly taking a load off the mains, then you will be preventing some amount of Low freq from going through the mains in the first place (like with a high-pass x-over between the pre-amp and amp). Am I wrong here?
If you do this with the REL you are not using the high level speakon connectors, no?
2 things I am thinking about with REL:

1.)Will it go low enough for my liking? (I don't get the warm and fuzzies from only going to 28Hz on the T/9i
2.)Would I be better off, as in, better integration integration with my mains if I went the Vandersteen approach and used the low slope high-pass filters combined with the high-level speaker connection with a 2wq. Not only that, but the 2wq hits to 20Hz and is considerably heavier and is also known for being an extremely musical sub.
It seems like I might be better off with the Vandy, but I get the feeling I shouldn't discount the RELs (They are somehow calling my name, LOL)
