10% would really be stretching it, no? Especially once it’s in your room.
I have 32 year old speakers that are totall crap in almost every way. Thinish MDF, little to no interior treatment, plastic surrounds and god knows how they cheaped out on the x-over.
But they sound good. So I got a Umic and REW and measured. Biggest issue was room modes. So I treated the room until till the room modes and impulse response was reasonable. Now the response is pretty dam flat from 40hz to 14khz Below 40 it drops significantly before bumping up again from 30 to 20. There is also still a null around 250. Not too bad, but enough I’m getting a sub to see if that will help. Above 1k it’s within +/- dB, which is better than I can tell with music. Distortion is low too, being only a percent or two off from some excellent monitors here. EQing both with REW and ARC3, make clear improvements in the sound, but honestly, blind, with a couple minutes between samples, I doubt I could A/B them. Back to back? Sure. So I’m left with wondering, given the limits of my hearing and my room, is ANY speaker going to make a huge difference? And I really really want the answer to be yes, since I hate everything about my speakers, except the way they sound.
