Default burn in ?

Any difference on these ?
How many hours ?

I also have a theory that a full range driver heats up a little (while playing) and sounds a little better past 30 minutes.

"And I'll tell you what: Beyond the simple matter of amplifier warm-up times, the longer I listened to the Voxativs in a given session, the better they sounded. Heaven knows why. " stereophile's review of their 8" full range driver speaker of the year.

Norman,

It will make a difference. If you're using an OB, they'll break in faster. Some boxes, especially those that restrict excursion a great deal (BIBs) will slow the process down. I often break them inside a well covered cardboard box in the basement to allow excursion and keep the noise down. Depending on what you choose to do, they may be at their best in 40 hours or continuing to change well past a couple hundred. Whatever you do, don't blow 'em up!

I need to get them hooked up first !!!!!!!!!!

I actually havn't blown a speaker in more than 2 decades.

I'm thinking phy open baffle (67" high, center panel 12-16", left and right panels 24" wide).

You can see baffle (phy) past 6:30 in their video, dont' forget to click on 480p !!!!!!!!
But his is dual walled with sand between layers.
PHY-HP famous speakerunits made by former Bernard Salabert of France. - YouTube

The last baffle I had, the wife liked it (wings folded back, not parallel though). Birch 1/2" ply, 60" tall, center 12" wide, left 15" wide, right 19" wide, driver centered at 36".

There is also the Human element.

You slowly get used to the new sound.

Yes...the primary components that experience actual burn-in are the synapses in the audio interpretation circuitry between the listeners ears!

I do know my akg headphones took 200-300hrs before they opened up.

And markaudio swears by it (burn in).

Just because it is (mostly) your perceptual system doing the burning in, it is nevertheless entirely real as a subjective experience. Think about it - there is ample direct evidence that our brain circuitry adjusts and refines its synaptic network in response to external stimuli. There is also the supporting element of those neural pathways that support the pleasure-seeking drives that underlie addictive behavior. So when the audiophile, who invests money, time and ego in pursuit of the pleasure of the listening experience, believes in burn-in and exposes his aural circuitry to the latest gear/mod/tweak is it surprising that the circuitry, over time, seeks to return the maximum pleasure reward to the listener. Add to this the supporting reinforcement of shared like experiences by like audiophiles and soon you have debates over how many hundreds of hours it should take to "burn-in" a length of speaker cable or interconnect. While speaker and phono cartridge suspensions have some plausible mechanisms that might subtly alter sound fairly quickly, there is no explanation for wires, passive components or assemblies thereof changing properties significantly past initial powerup.

Burn-in can be easily pre-programmed if the programmer is congruent enough.

how much did you pay for those?
did you get them complete or just the drivers?
can you measure fr response and post it?

2 sets of identical ludspeakers, 1 with fresh drivers and one with well broken in ones can clearly demonstrate that driver break-in is very real and independent of ear/brain familaeirt,
