Wharfedale Jade 3 aluminium tweeter problem

but I have problems playing some aggressive bass movement tracks, it seem the woofer hit the plastic surround...

If this sound is a somewhat loud pop, then the woofer has reached the limit of its excursion, and you will need to turn down the volume to prevent this, as damage to the woofer will eventually be the result.

as for the bass woofer I guess it's the same thing, hmm how come so hard to break in?

And no, break in will not solve the pop from over excursion. The only solution is to turn down the volume.

Breakin is a combination of several factors. The easiest notion to comprehend is loosening up the surround and the many important elements of the suspension. If wood is a major player the cabinet it contuse to dry or absorb or dissipate the atmospheric humidity . Paper cones I would think The crossover matures or burns in as any piece of good electronic piece of gear does. The magnetic elements loose some of their strength (not obviously until much older) our ears pick up all these perhaps small changes in aggregate and the burn now seems obvious and it continues throughout the life of the speakers,.
I know I have ny Father old JBLs approx. 57 years old which need to be refreshed.
Don't forget the changes you would get using a modern tube power amp. A tube anywhere in the path does not make the system tube in all that discussion..

Tls49: You mean that the speakers reach the excursion limit? hmm did you mean every speakers got this limit?

Mechans: From your experience, do you think this metal dome tweeter break in will ever happen? I mean it's metal! The build on Jade 3 is so rock solid, it's like very stiff stuff, all 3 components high, mid, low is very stiff indeed. I got a pair of Denton, soft dome tweeter, it seem not much burn in needed, it play pretty good

No not really, I have aluminum inverted tweeters on my Focal Electras and the tweeter was mercilessly and revealed everything in the system. I got some tube power amps and Holy Moly these tweeters found the right amplification and I don't mean rolled syrupy slow sound you remember from your grand parent's RCA console. No they quick crystalline and create a huge soundstage. Imaging that you can easily call holographic.
When I had friends over to listem I wouldn't say much about these relatively inexpensive tube monoblocs. Every comment that my speakers sounded a lot better, what did I do to get them to sound better. You know the punchline.
As for your tweeters they do break in hard or not it is suspended and has electronic elements and magnet in them. You are right they don't get burned in as fast as the other elements. Only time and listening will let you know if all the drivers in your speakers are maturing into a cohesive unit where they mesh well. The tweeter is a part of it but not the only one.. That said if you keeping your equipment as it is today you may be ready for a nice silk or whateve fabric tweeter. Do you any audio buddies around, if you do you can ry your aluminum tweeter with various amplification.
If you just can't stand them return them and get a fabric or paper tweeters. The time and discomfort with metal may not be worth it to you and I don't blame you. In another life I hade two systems The one with the Focals and many amps and sources, but wasn't until I found the right amps with the help of Trelja on these forums after 6+ years of trial and error (mostly error) I found nirvana.
The 2nd living room system is and was easy to listen to. Von Scheickert VR 2s powered by a smallish el-34 integrated. I had a MMF-5 turntable there and a couple of tuners one an old Sherwood and a Sansui the first cd player was a Music Hall MM CD-25 player.
I wish you luck be forewarned this hobby is addictive in some people.

Mechans: Thanks for your detailed explanation. I'm a poor music lover, always looking for budget gears, indeed I already found my audio nirvana with JDS Labs ODAC > Class D Audio 400C power amp > Wharfedale Denton 80th Anniversary speakers, this combination is musical enough to bring tears and joys when I'm listening, just that I'm trying to seek some dynamic improvements, though I'm not used to giant size of floor stander speakers due to immobility of moving those. I got an refurbished NAD 3020i, though I was trying to use it as preamp, it does not sound clear enough to me, and I found that I dun like to put preamp + poweramp as 2 blocks of big gears, in the end still prefer without preamp, control volume from computer DAC volume, this sound best to me.
