You’re already familiar with the enormous difference between 8KSE and 5200SE. The 8K non-SE is still, in my opinion, a far better speaker than any 5200SE adds a bit of refinement, etc., but an 8K is in a totally different league, in my opinion, if you have the space and the money is the same.

However, to clarify, you mention a 5200HCSE also, so are you intending to run these with a processor, Trifield, etc? Subs?
