From my understanding the glue was on the suspension surrounding the actual cone of the woofer? If thats the case, and provided it was a relatively small amount of glue, I can't imagine it would make any difference whatsoever to the overall sound quality. There also has been mention on here before, although I can't find where, of a stray glue drop appearing somewhere. Rest assured that you didn't get Factory Outlet speakers. With respect to them sending you the wrong driver the last time, it's possible that they misinterpreted your return of the first driver they sent. Some thought along the lines of: "Oh he returned the replacement, we must have sent him the wrong one."
