KEF-LS50 with REL T-Zero? Anyone?

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.

I just looked up the T5i and I don't see why it can't be set up like any other REL even using the low level input...I'd simply set the REL at wherever the KEF's low (without DSP) rolloff seems to be and set the level on the REL which I assume will follow the KEF signal level. It then doesn't need a "high pass" signal from the KEFs as it does it on its own.
