Would This Have Scared You Off?

Hi - I was thinking of buying an expensive speaker driver on eBay the other day. The seller did not know anything about speakers/electronics and the speaker was untested. She did not have a multimeter but was willing to buy one in order to get a DCR reading for me. After picking one up on the last day of the auction, I stepped her through the DCR test process.

She said that the meter reading was jumping around but when it stabilized it was generally in the 7.1 - 7.9 range. This driver is rated for 8 ohms and usually measures in the 4.5 - 6 ohm range DCR. I have measured approx. half a dozen of them myself.

Question - Would that higher DCR reading scared you off from placing a bid? It did for me, so I passed on it. I didn't really need it and there was still no guarantee that the speaker didn't have VC rubbing or some other issue. Thanks.

Yes, I'd avoid that because of the chance of VC buzzing, unless
you get a great return policy.

I might bid based on the assumption that it would need reconing or a new diaphragm. If it's a pro speaker, the trials and tribulations it could have endured are endless. Amateur repairs with non-OEM parts, months to years stored in a leaky van or chicken barn, all-night dubstep parties...
