Wow.
I agree with Corelli.
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!
1500 is upper midrange. If you do a search for frequency chart of musical instruments, you should find what you are looking for. Erik, I have built using buttererworth, bessel, linkwitz riley and chebyshev. I believe that you were looking for bessel, this has a very smooth impulse response and I agree with you, I suspect the designer was most likely dealing with some other issue that they used this dip to deal with it. |
@jheppe815, thanks for the information -- very reassuring. My top end is pretty smooth so maybe these have more hours on them than I thought. Overall I like them, but I need more time to adjust to their sound. They’re SO dynamic. I’m used to the much more delicate sound of my Omega High Outputs. I’m about to switch the 4349s over to one of my tube amps and play some classical guitar. If it sounds as real/natural/correct as my Omegas, that will be a great sign. If anyone thinks I should start a dedicated thread for rhe 4349s, let me know. Not sure how much interest there is. |
@toddalin thanks for the explanation and video. I thought both sets of speakers came off pretty bad in rhat video, but - and feel free to accuse me of being biased - the JBLs were much more tolerable. The Klipsch sounded quite shouty to me, whereas the JBL had depth and warmth (warmth relative to the Klipsch that is). I’ll also note that the JBLs in the video were the 4367s, the model above mine. According to Erin at Erin’s Audio Corner, the 4367s measure and sound great. Erin is also one of the guys on the ASR 4349 thread who thought the 4349s measured terribly (I like Erin and subscribe to his Patreon). |
