The important thing is that the break-in must be longer than the return period. See a pattern ?

Here's my favorite break-in method.
  1. Find some mono program material. Old Beatles recordings work well.
  2. Connect your speakers out-of phase (i.e. connect the wire backwards on the back of one of your speakers).
  3. Put your speakers face to face so there is less than 6" of space between their fronts.
  4. Get a heavy blanket and drape it over the speakers. This will muffle the sound that leaks out while they're playing.
  5. Turn on your equipment, insert CD, turn up the volume all the way, and hit play with endless repeat.
  6. Now leave the room immediately and let the music continue for 30 days or the duration of your money back guarantee, whichever is shorter.

Because the music is in mono and the speakers are out-of-phase and facing each other, you should actually hear very little sound even though the speaker drivers will be moving quite a lot. And who would want to hear the sound from un-broken-in speakers??

I figure if you do believe in break-in, you should go all out.


Did I mention I'm a non-believer? \:\)


DAMMITT!!!! 6"???? I thought it was 16". Woe is me. This explains why everything sounds a little off, even with a solid state maple shelf, crystals and magic pebbles.

"In an electrodynamic driver featuring the usual surround-diaphragm-spider construction, driver suspension mechanical compliance plays a key roll in determining the measured value of various driver parameters. All of these parameters will shift as the mechanical compliance of the driver's suspension shifts in value. The bulk of a driver's compliance shift will occur at the time of initial burn in.
Subsequent shifts in compliance are largely temporary in nature. An example of one such mechanism contributing to such temporary shifts is that which arise from the elastic deformation of butadiene-styrene surrounds. Given sufficient time to recover, these changes tend to reverse themselves and the driver returns to its pre-stimulus state.
As the enclosure compliance in both totally enclosed boxes and vented cabinets dominates that of the driver for most practical implementations of either type enclosure currently in production, any potential changes in system amplitude response attributable to changes in driver suspension mechanical compliance tend to be minimized. Normal production unit-to-unit driver spec variances can affect final amplitude response of a system to a larger degree than that expected from normal pre- post-burn in driver suspension compliance changes."
