KEF-LS50 with REL T-Zero? Anyone?


I am putting together a second system in our casita.  My source is a Bluesound Node2 and my power amp is an older Audio Research 100,2. (100 wpc SS).  I just bought a pair of KEF LS50s.  They are not setup yet so my curiosity about the need for a sub is speculative.  This is a small room with limited space so if I think I need a sub it will have to be very small.  Hence the Rel T-zero.  It is the perfect size to fit in the open cabinet I will place it in.  I have owned larger Rel subs in the past so I am familar with the brand.  The Zero is a tiny sub...so much so I wonder if it will be worth the expense or effort.  I've heard the LS50 and I know it has good bass....for it's size but just wondering if that extra bit of low end the Zero will provide will compliment the LS50.  Knowing the limitations of the Zero I am not setting my sights too high but just wondering if anyone has heard this combo and can share their experience.  Thanks

I have the T-Zero, it's good but really better to use with a desktop computer system.
I know you would be much happier with the T5i.
Please use my learning curve, and don't repeat my error, get the T5i or larger. My larger subwoofer arrives today ;-)
I agree lak, even the T5i is marginal in terms of the impact it has on the system.  Space and finances limit the degree to which I want to enhance this second system in a casita.  I am beginning to think that unless I can get a proper sub (T7i or above) I might just be as well off leaving the sub out of the system....particularly if the LS50W has improved bass performance and ends up being the keeper.  I have always had some form of a subwoofer in my system for the past 25 years.  I started with passive subs, them moved up to a larger REL (Storm).  I now have Vandersteen Quatros with the built-in subs in my main system.

Thank you for your advice.
I use a Klipsch sw308 sub with my ls50s and this is a very good pairing, if you can still find one.

The sw308 has 8" main driver and two 8" passive radiators and delivers a lot of detailed bass from a relatively small package.   Results are top notch.

I’ve debating adding an external active crossover but this sub meshes so well with the ls50s in my 12X12 room that I have happily opted to just keep things simple.
Save some bucks and try one of the Q108MKII RELs for sale on eBay...I own one of these (along with a similar vintage Q150e that also is a great sub) and they're amazing, and for around 200 bucks for a good used one you can't go wrong.
I've been listening to the KEF LS50Ws for about a day now....with and without the REL T5i.  They are pretty amazing.  Very similar to the LS50 but tunable to my room.  Something about those built in powerful amps that seems to focus and allow the speaker to project a rock solid image and soundstage.  A nice incremental upgrade from the very fine LS50 but not a "night and day" difference.  I'm still feeling my way through the KEF control app, experimenting with various settings to try to find the right mix for my room.  The basic settings seem to get you most of the way there while the "expert" settings offer a bit more refinement.  Adding the REL T5i to the equation complicates matters a bit.  I've used a REL sub in my main system for almost 20 years and have always used their recommended speaker level connection.  With the LS50W this is not an option but I am able to run an RCA cable between the KEF and the REL. I'm a little confused about how to combine the control settings on the REL with the settings in the KEF app.  KEF seems to recommend setting everything on the sub to max volume and highest crossover and make the adjustments in the KEF app.  Is this best?...or does it make a difference.  The KEF app has the option of using a "high pass" mode...or not.  Using the app to make subwoofer adjustments is like using a remote and much easier than getting up to make the trial and error adjustments on the sub itself.  Anyone with advice or experiencing setting up a REL with the LS50W?  I would appreciate your input.
