I agree and that's kind of my point. Who (other than Richard12511) is going to notice a 1dB difference between 20-40Hz?
Maybe I'll try recording it(umik-1?), but there's certainly a noticeable difference between my 2 target curves on some songs. It ruins some songs for me. I'd be shocked if others couldn't feel it, but maybe I'm wrong. At loud volumes, I feel like I feel it easily.
I have tried both shelving and peaking filters when adjusting a pair of Genelecs to my listening room, including ones that slope up gradually with frequency. Even small adjustments are audible. 1db that affects that entire top octave is "very noticeable."
Oh it's definitely audible(more audible than the 20-40 bass difference), it just doesn't affect my overall enjoyment very much. Mostly what I've found with my top adjustments(usually land between -0 and -3.5 at 20kHz) is that I'm trading small amounts of enjoyment for small amounts of endurance, but I could live without it. Bass on the other hand can be make or break for me.
Interesting that you've tried sloping up the 8351s treble. To me they're already hair too bright out of the box. Just goes to show how different preferences can be.
Really? You can hear 0.5-1dB differences in slope from 20-40Hz? Amazing.
At loud volumes and certain material I can feel the difference. I have two different sub 50Hz filters I run, .5db/oct, and 1.2db/oct, and I regularly flip back and forth(2 separate convolution files). I've also found that there can be a fine line between pieces of the house vibrating or not vibrating, and sometimes one slope will excite that, but not the other. I think it makes a real difference for some music, and none at all for others. I hear it less so than I feel it, but the difference in joy is greater for me than that top octave difference, as I just care about that range so much more. The 1.2 bass slope ruins some songs, but awakens others. By comparison, I fiddle with the top shelf filter much less. Could be a personal preference thing. 20-100Hz is maybe the most important 3rd of the graph for me, but I'm also kinda a bass head.
The bottom line is that a -6db downslope starting at 7kHz is not trivial.
I'm with you here, and I wouldn't buy this speaker because of that. It's just too much of a roll off in my eyes. One of the biggest I've ever seen.The Revel F328Be looks closer to what I'd like. My defense of this speaker has been about the reason for that downslope. My opinion is that it's an intentional deviation from neutral, not a failure of engineering(similar to the 800 series B&Ws). I think Magico(like B&W) has the engineering to get basically whatever response they want. They chose this response because they think thinks it sounds better(maybe internal listening data?), even though I don't agree with it.
I guess inserted myself in you and
@Beave's conversation because I thought you kinda jumped on him unnecessarily for what was a fairly off the cuff statement that was almost(but not quite) correct. I see it mentioned on here quite a bit that many don't really pay attention to errors above 10kHz all that much. Generally, I don't either, though I'd still prefer flat. I didn't think Beave was going out of his way to praise Magico(but maybe he has history I don't know of) unfairly, which is what seemed to upset you. I also think he was mainly thinking in context of this speaker(50-20,000Hz), and I can forgive him for forgetting that bottom octave.
I'm curious, though, other than 20-40Hz octave, which octaves would you consider less important than the top octave? Are there any octaves above 100Hz that matter less to you than the 10-20kHz octave?
