Driver matching vs break in period

I installed a new mid range driver for my B&W 803 SII and noticed that the image shifted to the speaker with the older driver. I got out my radio shack SLP meter and found that the new mid range driver was about 2-3 DB lower than the old driver in the other speaker. I ended up reinstalling the old driver and putting the new one back in the box. The question is: Is this a matter of matching drivers, or is a matter of allowing the new driver to break in, or is a bad driver? Any thoughts?

Did they have the same part number?Also switch them (Midrange drivers)between channels to see if crossover is ok.

I guess I should have said,try the new driver in the good speaker and see if it still has a big loss. I don't think that kind of loss is normal.Make sure the plus and minus are correct also.That my 2ยข

That sounds like a good move.I've had hard,or a little brighter on a couple mids in the past.On woofers,I've had boominess until it broke in.I can't ever remember a quieter one.At least they will know of the problem so you don't get stuck with an unusable driver.

It sounds like a typical I don't want to be bothered answer.Just give me my paycheck.They used to work with a customer from what I remember.
