Can't tell the difference in sound even though one registers 4.1 and the other 7.6 on the ohmmeter.  These were paired with some ESS AMT Ribbon tweeters in a 2-way system.  I still have one of the tweeters.  Have both of the woofers for sale in this auction.  You can mount them with or without the facing plates that are included.

Thanks for bidding!
