The 3677s don't roll off that much, and it's addressable by room correction. I never found it to be an audible issue really.I know this is a Synthesis thread but thought I'd ask the following in here as I know many of you have experience with the JBL 3677. E.g. @fallinlight @Smurfin @Arcam_boy @LittleNipper
The specs give a frequency response of up to 12kHz. Which is a fair bit lower compared to the more regular 20kHz I typically see, and the XTZ M6 I currently have are rated up to 30kHz, so 12kHz is far below that. I know our hearing doesn't go that high so above 20kHz is probably not that important, but what about that 12 to 20kHz range? I'm just wondering if that rolloff at 12kHz causes any audiable issues - is anything lost compared to something that goes higher like the M6?
I know @fallinlight you were saying you were told to pay attention to the highs when comparing the 3677s and the M6s and iirc you described them as falling apart. But as the 3677 are highly regarded, how much was that actually a real issue in normal listening? And was it just in music or movies too? Was this reduced frequency response perhaps the reason you couldn't quite commit to the 3677 over your M6?
And to other owners/past owners, did you notice anything lacking due to the 12kHz rolloff? Most people love them so perhaps everything else outweighs any drawback from it?
Reason for asking is the 3677s are on my wish list for L&R, but as they are hard to find I'm also considering a slightly different set which also has the same 12kHz frequency response...
Thanks
Here's a rough measurement I took of one of the 3677s I owned, showing pre and post room correction.
