Spendor D9.2 Run In

OP,  “speaker needs 300 hours, why isn't the manufacturer running the speaker”.

That is simple. Cost. Think of the space required and taps to power them. Not in this price category.

Hang in there… only 12.5 days of playing. 

I personally found the these speakers to be a bit too bright.

Give them a couple hundred hours. Speaker drivers do need to settle in. 
 

All the best.

I'm thinking I might move them, aggressively.  We shall see.

I have not purchased any "new" equipment in decades.  Back then my speaker break-in was done out of the box, connected to an old receiver in a closet.  Speakers place face to face with one speaker hooked in reverse polarity.  Receiver set to an FM music station, Mono mode and ran a bit higher than my regular listening setting.  After a couple days, I reverse the speaker polarities.  And run them another couple of days.  Reset the connections to proper polarities and in Stereo Mode another few days.   Took a few days to a week, but never was disappointed because of "break-in".
