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!


One other thing that I'm thinking about is that ASR is measuring the speaker at 1 watt.  Lots of speakers measure close to flat ONLY at 1  watt and then have their performance rapidly degrade when louder or heated up by playing (i.e. thermal compression). For a speaker like this, excellent performance even when played hot would matter more for me.

Ok, another thing, there are some crossover alignments which forego absolute perfect amplitude for excellent impulse response, the name of the crossover alignment escapes me, but not impossible this is an example of it.

If you want to know exactly what the crossover characteristics are, it’s quite easily done. Get a used audio frequency generator and oscilloscope and plot the curve with some graph paper or Excel.



@erik_squires I think you were thinking of Linkeitz-Riley crossovers which are nominally -6dB at the crossover points.


And as far as the ASR crowd, I have a sneaking suspicion the individuals commenting have never heard the JBL 4349 or heard of Linkeitz-Riley filters, let alone the theory behind them.
