3-4 dB dip at crossover region: what should I listen for to hear it?


I haven’t posted here for about 10 years but thought I’d jump back in to ask about my new JBL 4349s. According to measurements on ASR and even JBLs own graphs, the 4349s have a 3-4 dB dip in the crossover region at about the 1.5 kHz mark. What should I listen for to hear this? I understand that music in this range will be quieter, but I’m not hearing any suckout compared to my Omegas or other speakers Ive had in my system. I’ve played some clarinet and violin concertos, two instruments that spend a lot of time in this frequency range, but I can’t hear an obvious difference. Am I listening for the wrong thing? I’d like to be able to hear this deficiency for leaning purposes if nothing else, so any pointers are appreciated.

 

Many thanks!

Today sound pressure meters are very inexpensive

get one with a tripod fitting

next a CD (not LP) with test tones, many single frequencies, and you set the mic at seated ear height at your listening position.

They don't have to be laboratory accurate, just give you relative differences, i.e. + ____ db or - _____ db than the prior frequency.

My test tone CD has 29 frequencies to compare. Expensive, you could find something else

 

You are measuring the space as well as your speakers. Slight relocation, slight toe-in adjustments differences can be found.
