dc resistance mismatch question

Speaker Asylum

General speaker questions for audio and home theater.

I need to replace one driver of my 1997 Kef Q55 that I own since new. Unfortunately, Kef don't have spares for that old production, so I was looking for used drivers. I've measured DC resistance on both sides to have a clue to get a good match. But, in many months I didn't find drivers with the exact match, except for one pair that I lost on a bid. All of the rest, have a little more. Both of mine are (dual concentric, only one mid woofer is blown) had:
mid woofer 7.2 ohms
tweeter 3.2 ohms.
The ones that are available have:
mid woofer 7.9 ohms
tweeter 4.0 ohms.
What can I espect from this mismatch, it is a neglectable difference or can cause a noticeable (or subtle) different output level from the other channel? Thanks in advance.
Btw, I have double checked from where this drivers are taken and has exact the same code from crossovers, drivers and of course speakers version. Even the drivers production number is more or less close.
Thanks in advance
