Urgent help regarding Exams (question on Burn-in)

Thread Starter 
Giving an exam on Enterprise Resource planning..and the topic of 'burn-in' will be coming under Product Failure rate.

i.e its importance to prevent early/premature failure of the product

i am giving example of speakers/headphones as products which need burn-in/run-in like Cars (which need to be driven under 30mph or so for the first 1500 miles or so .depending on the manufacturer)


is there any formal advice given by speaker/headphone manufacturers to not play the equipment at high volume level OR to use pink-noise etc to burn-in?


basically ..what i am asking is that...do audio companies acknowledge requirement of the burn-in in any form?

if i buy a set of speakers today and start playing them today itself at maximum operational volume until it starts clipping....will i be damaging them?

I've heard that some companies include a little note with their products suggesting some hours of burn-in before critical analysis of the headphones. I think MEElectronics did this (don't know if they still do), and some other ones that I can't remember.

Yes, many manufacturers do specifically state that the product should be burned-in before use. From the manual for my Energy C-100 speakers:

BREAK-IN PROCEDURES
It is VITAL that your new C-Series speakers be allowed to break-in properly
before you perform any precise set up procedures,system adjustments,and
before you play them at higher volume levels.The best method of performing
the break-in is to play a full range musical passage at a moderate level as long
as possible.Utilizing the repeat function on your CD or DVD player can assist
greatly.Optimum sound will not be achieved until approximately 100 hours of
playing time.After break-in,the volume level can be increased.Do not play the
speakers at high levels until the break-in process has been completed.The
transducers need to “loosen up”,and until this occurs,damage can result to
the transducers.

My new subwoofer sounded like trash and i was sorry for buying it until like 2 or 3 days later after a few hours of working in the driver. It just didnt move far enough to push out lows, and to move fast enough to be musical.......then all of a sudden it was sounding great. I believe in physical burn-in of drivers, and burn-in of tubes because i am a ham radio operator and have used 2000 watt radio amplifiers and also tube radios and i can see evidence on my watt meters of burn-ins affects.

I dont believe in hours of wire and cable burn-in.

Caps probably burn-in a bit, and probably change sound depending on the type of cap and the temperature theyre at, and as they get older, they dry out and change also.
