REL T/9i or S5


Looking to add a subwoofer to my system in an 11 by 18 ft room.
For those familiar with the REL line is it worth it to spend the money on a new T9i or move up to the S series and buy a used S5 with the intention of adding another one later?
Right now the new S series is beyond my means.
Thanks

Rythmik F12. Save yourself some cash and get a superior product. I was a REL owner. Switched to Rythmik and have zero regrets.
Thanks for all your responses. I'll be getting something in the lower end of the S series.
Pair of used S3 will outperform T9s. I have the S3 SHO and it blows away the Strada lll I had before.
That plain looking 400 watt 8" one that’s wireless with auto standby and an iPhone remote control w/equalization app? It retailed for $599. but can be found two for $899?

Sorry I can’t remember the REL model number, SLF something and a funny name? I think the Absolute Sound reviewed the 12" version?
Wish I could be of more help, sorry.
There’s no substitute for quality the S line is considerably  better. All the best
I have a pair of T9i's that I use with my Tannoy Stirlings in a room a little bigger than yours.  I can't speak to the S line, as I never got the opportunity to hear them.  I'm sure they're wonderful.  But I find the T9i a *highly* musical sub.  Very fast and tuneful, which is what I want in my bass.  I want tones from a double-bass, not boom or rumble.  They certainly could overpower a room and muddy up, but they're so adjustable it's easy to avoid that.
One of the nicer subs I found in that range the Rythmik F12G.  I owned a S/3 for 4 years and tried T-9 lent by a friend for 2 weeks.  The Rythmik is worth looking at.
I purchased a T9i for $750 and later, an S3 SHO for $1000, both new, from magnolia.

I’d take 2 T9i’s over a single S3 SHO.

The S3 SHO does seem to have quite a bit beefier driver.  If you can do 2 S3 SHO’s that would be pretty sweet.

I’m currently using a T5i with great results in my small listening room.  I will get at least 1 more if not 3 more eventually.

Rels subwoofer guide is very useful.  You can easily get too much sub for small speakers.  You won’t be able to properly integrate the sub if its too large for your mains.  The S3 SHO with Totem Arros was a mess. Bass went from too quiet to overbearing with one click on the volume knob. Something to keep in mind!

Also, 4 T9i’s might be better than 2 S3 SHO’s
What speakers do you currently own? Look at REL’s subwoofer matching, they are pretty specific. I can tell you the T9i is a hell of a sub for the $. If you can do two of those, depending on your mains you would be happy. FWIW I have an S510 and plan to add another soon. My room is a bit bigger than yours...
