Hallo! I am a newcomer to this forum. I would like help to recicle for home use a pair of church loudspeakers I bought for 5 euros (the pair). They are custom-built (probably) by a small italian firm (Melloncelli). The lodspkeakers work ok and the sound is good. This firm still exists. Also asked the firm to provide all possible information. Problem: since they are built for human voice, there only are mid-range speakers, 9 (nine) of them. So I would like to: build separately two woofers to connect to the B out of the amplifier (Marantz PM-45); replace one or more mid-range with tweeters. My main question is: how many tweeters to replace as many mid-range? Thanks for any help. Maurizio
