I doubt you'll ever hear it. Tests have proven that when dips are narrow and near adjacent frequencies, the human ear can't detect them. Even very large dips exceeding 12 db. It has to do with second/ third harmonics canceling out the dip somehow. I tried to find a well put together video that I watched regarding that, which explained it in detail with graphs, but I was not successful. I believe it was on YouTube. Maybe someone reading this has a link.
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!

Thanks for the reply @ellajeanelle. That’s really interesting. According to most of the posters on the 4349 thread at ASR, this dip is an unforgivable sin. I’ve been taking hifi seriously for about 15 years but have only recently been using measurements to guage how gear might sound (though I’ve been using measurements for system matching from the beginning). Lots to learn! |
Trust your ears. As a musician you have a huge advantage in that your brain is very familiar with live music. Don't become like the rest of us that become hypercritical about things that in the end are not so important. Listen to a broad sampling of music you love. If the speaker checks off all the boxes important to you, measurements do not mean much. Good luck. |
