As I said we used an KF92 even with R5 so we did not compare raw bass performance with the LS60 has too.
But we did use ls60 with and without sub .
Many people might not have felt the need for a sub with this speaker , but I had one for the last 24 years in my music system
This should hopefully last me a long time so I will get the means to eq the bass too , I’ll start of with a WiiM pro with its PEQ and possibly also my Music server as EQ .
Will have think about if Dirac is strictly needed and possibly also get an mini DSP if that’s the case .
Edit did not auditioned the R5 without sub can’t say how it performed without it .
