As others have already said, FLETCHER MUNSON
Oh how I wish I’d known about Fletcher Munson when I was flipping speakers! I went through everything from little Harbeth P3ES to their biggest M40.1 to giant Tannoy FSM with 2 x 5” cones per box! From Focals to Transmission Lines…
I never found a speaker that satisfied me at low volumes!
IMHO, the options are :
- Adjust your Subs to your taste. That’s what I do.
- Get an amp with a Boost button or get some form of EQ.
- Use Headphones.
Or….if you never listen above 60db, have you ever tried something like a Cambridge Audio EVO One or Naim Muso? Single box with speakers inside. You might be pleasantly surprised & be quids in when you sell your existing kit.
Good luck!
