A friend told me JBL DD67000 is actually very bad speaker, is it true?

According to him, those Tidal, Kharma, YG, Magico, Vivid G1, Grande Focal and German Physik are truely good speakers, JBL ain't no good...and his reasons: JBL is boxy, horny coloration as hell, zero imaging.

is this true?

It all depends on what one is looking for in an audio system.

If one is looking for that big, dynamic, lively "rocking" sound, the JBLs might be a good choice.

But, if someone is looking for a more detailed, open, more neutral, more accurate (timbre, harmonically), better imaging, speaker, the others will do that better. At a substantially higher price.

As you might have surmised, I agree with your friend.

JBL speakers come of as a bit of a 'blunt tool' to me. They make everything sound as it it is coming from a high quality PA system. They don't get out of the way of the music, they always impart their sound.

Also, I agree, that they offer no real imaging. They create a big wide soundstage, but no real layering, or imaging, within that soundstage.

I have heard: Everest's, Summit's, L100's, and a few more.

It also depends on who’s making a statement like the above. Yes, I as well find the DD67000’s to provide a (in your words) "big, dynamic, lively "rocking" sound," but to my ears that in no way excludes them of most of the traits you’re lining up in the last quoted paragraph.

For one I find they image extremely well, but it’s more of a projected-into-the-listening-space kind of presentation that ignites the air, rather than the more laid-back, "spacious" (overly so, in my point of view) and thinner sound that comes from many of the brands of speakers you mention (especially the German Physik’s). Aspects of the Everest’s sound may have character, but I find it’s much less intrusive compared to speakers that are dynamically restrained, malnourished overall and less present sounding. Talk about character.

You describe them as (albeit high quality) brutes, which is a typical statement of many an audiophile; whatever possesses dynamics and full-bodied sound by definition almost must be devoid of nuance/subtleties, transparency, accuracy and spatial capabilities - indeed, haven’t we heard that before. God forbid power and presence of presentation, "hi-fi" is about the finer things where you listen to softened up music in what’s effectively an audio version of the past tense. Bollock’s, I say. This kind of "hi-fi" is what really imparts character to reproduced music and it sucks the life out of it. Or, shall we say: to each their own?

Once you hear a good JBL system, it will match anything. Plane and simple.
