JBL's cabinets sure aren't what they used to be

I do miss the blue JBL monitor colour, otherwise they look kind of like the 4345 which is fine by me

Come on guys, patience is a virtue!

I have been away from home this weekend. Will post some pics later this week.

The sound has changed very much from friday to sunday.

Cool, sounds good. Oh yes, it will. Just wait until a month from now. You'll be in audio heaven!

Can you describe the changes you experienced?

My 4365 sounded thin in all registers out of the box. And also veiled to some degree.

But now it is starting to sound good!

I played a 16hz pink noise tone all night on high volume, can not hear it anyway!

I have plans to make my 4365 white using plastic film, and white grille cloth.
I have done it to speakers before with good result. Makes then dissapear a bit on the white walls.
Pictures will come when it is done.

Behind the green blanket stands my 4429 center. It sounds crazy good!

I will make a frame with white speaker grille cloth in front of it. Fastened with magnets on the bench.

Please don't destroy the speakers and it will not sound any better. Just leave them as it is.

What are you doing

Breaking it in. What is your concern?

I repeatedly played 1 minute noise, 1 minute digital silence, so there should be no probem with overheating or something like that.

Destroy? Everything is 100% reversible.

If you would use a pink noise with 20Hz-20kHz with low volume, this is more resonable than only using 16Hz. You are beyond the speaker specs.

Just play some music thru the speakers.

I play music the whole day on normal "background"" listening level. Then tonight I played a combination of 25hz sinus, 20hz sinus and 16 hz pink noise with digital silence in between. The volume was slightly higher than normal listening level.

Yes, the S4700s also sounded both thin and veiled at the same time new out of the box. A bit disappointing to me at the time.

What happens is that the midrange and treble opens up to a large degree, while the bass becomes full and powerful.

So, the sound becomes more dynamic and transparent.

It took a long time to break these in. They're now 6 months old. I'd say they're still breaking in, but I might be wrong on that.
