Seriously, I've heard these speakers, and they seem to have a lot of the same attributes that made Quarts popular but annoying - bright highs, vocals getting edgy, and not much warmth - more of a hard sound.

They seem to be really impressive sounding in a display board, but not in a car, especially over time - they seem to have the kind of sound that causes listener fatigue after half an hour or so.

Not at all like Morel, Dynaudio, DLS, Alpine F#1 or even Alpine X type.

Does anybody else hear this or is it just me?

I think it's about price point. I have never personally listened to Diamond, but hung out in a caraudio channel on IRC for god-knows-too-many-years where everyone has an opinion and barely any of them were informed. From what I heard on there and on here, for the price point they are softer then Focal or MB, which is what most people who buy Diamond are looking for.

From doing a quick ebay search on DLS, Morel, Dynaudio, you're looking at $500+ for a set of components. Set of Diamond D600s is $175 shipped from ebay.

I just put diamond audio components in the front of my sedan. They sound incredible but they're a little too bright for me.

mint condition - $200 shipped

I had a Diamond audio TDX 12 sub in my old car and it was the loudest sub that I have ever heard. there is no comparson to it the W7 doesnt have anything on the TDX sub

is it the Hex s600 model???

Personally, I don't like any metal tweeters. They all sound too bright to me. I'll take a silk tweeter any day. Diamond does make component sets with silk tweeters also.

Diamond buys their tweeters from a German company. The version they buy from them is available either way. (I buy the same tweeter in silk form for use with our house-brand avincar speakers). But their "high-end" stuff is available in aluminum only.

Either way the Fs of the tweeter - the resonant freq - is kinda high. Why our house brand is low end for us, I guess... (Our house brand speakers go for like $240 a set for 5 or 6" comps).
