Greetings- I have a chance to purchase a pair of 2240 that need a recone locally at a decent price. I read here that a 2240 can be reconed as a 2245. This may be a stupid question, but will the reconed 2240 take on all of the same parameters as a stock 2245? In other words, will the effeciency drop from 98 Db to 95 Db, and the low end of the FR from 30Hz to 20Hz? Thanks for your help. wpod
