Adding Home Theater To 2 Channel System


I have a two channel system that I am very happy with located in a dedicated listening room.  I am considering how to add home theater without giving up the two channel sound that I enjoy.  My main speakers are Avantgarde UNO’s (horn speakers - 18 ohm, 108 db sensitivity). Avantgarde does not make a center channel speaker.  I assume that I will have a problem matching any box speaker center channel speaker with the Avantgarde - my worry is incoherent sound.  Is this something I should worry about?  Are there center channel speakers that might be a good match (I have been unable to find any obvious candidates ohm/sensitivity match)?  Is it likely that I will need to find a new set of front speakers from the same brand as the center speaker?

The rest of my setup: Pass Labs XA 60.8, Audio Research Ref 6 preamp, SME 20/2 turntable, Lumin x1 streamer, Ayon CD player, REL 812/S subs (2)

Thanks to everyone for the terrific and consistent feedback.  It will save me a lot of time, money and disappointment.  Your advice on this is invaluable.
I love the idea of having two separate systems, one for music and one for HT.  That said, I am having a hard time overcoming the amount of equipment clutter this will create ... 5 speakers, more subs, receiver, interconnects, cables.  I guess that might just be a “me” problem.

I already have 2 REL 812/S subs.  Adding two more is something I was considering just for music, nice that it makes sense for HT as well.  REL is very clear that their subs should be connected to the high pass on the sub and from there directly to the amp for music … no connection to the preamp.  This is the way I have set them up.  I guess/assume that for HT, the connection to the subs should be to the .1 LFE and then to a receiver(?). 
A lot more response here than I expected.  Thanks so much to everyone for helping me with this.  Reading over the advice here and talking with others I think I will get into the HT pool in the shallow end and build from there as I learn or as/if needed.  That would have me start with a receiver (for the surrounds), drop down screen, projector and two surrounds.  This gets me in the game.  Again, thanks so much!
