Nick is asking about the new "Classic Series". A less expensive current offering from FA. The 68 you mentioned was the forerunner to 688 and was from the original Signature series.
The Dealer is correct. The 9900 revelator (currently used in the 688) was only used in the $8800 flagship 88 speaker.
The dealer is also correct about the tolerances. Wilson matches its drivers to within 0.5db. Focus Audio matches their drivers within 0.25db.
Doug from Soundstage magazine on one of his posts at AA said in measurements at the NRC, the drivers in the FA688 were the closest matched of any drivers that Soundstage had ever tested. The 788's werent reviewed at the time and I'm sure they would test similar.
From what I have been told FA buys their drivers in batches of 200 then matches them and keeps a record of their results of file. Should a driver ever blow the measurements are on file so the replacement driver would be almost identical.
