Breaking period

Hi,

I recently bought Tannoy F1 custom.They are nice to listen,but
treble is thin but clear.Old spk sound open in High freq. area.

What can be it?
Do they need breaking?
What differnce one can find?
Do tweeter sound quality improve?

Pls. share your experiences.

absolutely no offence meant, and please take this as a Joke.....but "breaking" might be very bad for the speakers.....breaking-in on the other hand might be worth considering....

That was a nice one, psychotropic

it could well be that it needs breaking in. normally the new model is mostly an improvement on the previous. breaking in could take anywhere from 10 to 100 hours

I have no experience with these particular speakers but I cannot think of a brand that does not have a breaking in period after which sound improves dramatically. You can of course accelerate the breaking-in period by using the popular method of: wiring one out of phase, having them face each other and playing music that spans as much of the frequency range as possible. If not, simply give them time and they'll sound a lot better after around 10 hours of play.

Particleman,
I'm curious to understand why this accelerates the break-in period.

Thanks,
Jinx.

OK,

As I know breaking causes improvement in Bass department(deep)
I wld like to know does treble improve?currently treble from my spk.
are thin.Will they open, & become wide,sweat by breaking?

Spirovious, the word is Break-in or Breaking-in. Not 'BREAKING'. When your are breaking something, you take a hammer to it and smash it to pieces. I am sure you do not want to do that your brand new Tannoys.

Break-in is also called 'burn-in', or 'run-in'. An analogy I can think of is when you buy a new car, you find it a little stiff. When you have driven it for a little while, you will find it is responding better to your commands.

A loudspeaker consists of a cabinet in which there are two sets of devices. One is the crossover circuitry, the other are the 'drivers'. The drivers are the units that generate sound for you.

The driver is a electromechanical device. Look at the following image of a driver.



Th two important parts are the Diaphragm and the Spider. The diaphragm vibrates when it gets electrical signals thereby moving a volume of air to generate the sound. The diaphragm is suspended between the outer frame and the Spider. The Spider is made of varnish-impregnated linen and a new Spider is usually stiff. It does not allow the diaphragm enough freedom of movement. As the driver is exercised with electrical energy, the spider loosens up allowing the diaphragm to move freely.

Driver burn-in is considered relevant only for low frequencies (woofers) and mid frequencies drivers. Why not for tweeters that generate high frequencies? Simply because the tweeters are very small units, have very little physical movement, and many tweeters operate on principles that are different compared to a conventional LF and MF drivers.

Cheers

Did you change any of your cables? Are the speakers in the same position as the ones before?
Lean sound could be due to many reasons but most commonly due to RF/EMI being picked up by cables. Try moving cables away from power lines and raise them from the floor.
Also, if have any highly reflective surfaces at the first reflection points (side wall between you and speaker) these will increase the treble.
Try playing around with speaker placement.
If all else fails, PM me your email address and I will send you some tips sent to me by the owner of Shunmook (Shun Mook Audio, Inc.) to overcome this issue.

Why not share those tips with all fellow members?
