Sub Pairing With Harbeth 40.3 XDs

Why would you need a sub with those Harbeths? They should sound good just as is...

needing a sub and wanting a sub are two separate camps…I initially tried it just for fun and found adding a sub to be a total game changer. 

Have you called Harbeth or visited a local retailer to listen?  I personally like REL because of their high level connection.  I makes sense because they act like woofers if dialed in right.

Exactly. I want the clarity the Harbeth’s bring ,however, also want the ability to emulate the feel of a live concert where the kick drum is focused and hitting you in the chest like Thor’s hammer.... 🎉

The question is do I need 2 or just 1 ....my room is Medium large ,but open ended on one side , in the process of treating it as best I can...

I've never felt the need for subs with my 40 series, but if I were to go down that path, I'd look at REL.  Sounds like you may prefer a different kind of speaker... maybe some large JBL's or Klipsch Cornwalls.
