I have a pair of Kali LP6 set up on my desk, which is a small spare room (approx 10.73 cubic meters, 378 sq feet). I share this space with my girlfriend so I can't convert the room to a full studio. I have bass blockers (rock wool) set up behind the two speakers (they are 120x60x10 cm) to deflect some frequency buildup. However, I get an increase in DB when playing the B and C notes (anywhere on the fretboard) so around 246hz and 261 etc. Is there a software eq I can use to target these frequencies to adapt to my room mode? I can't do much more room treatment b/c as I said I share the room. When I pull my speakers away from the wall the DB increase goes down, but is not eliminated. I don't have a measurement of the DB increase, as I don't have a mic to measure with, but I could possibly borrow one. I tried the cheap EQ in Garageband and was able to target some frequencies and it seemed at minimum a 9db decrease was needed to compensate. Any advice?
