Hi, I recently discovered a pair of RTA 12's in the basement of the warehouse I work in, and theres a pretty good chance I can get them for really cheap price, maybe even free considering the condition. They have been down there for at least 6 years and aprox. 2 years ago the basement flooded a little(1 inch maybe) and the bottoms of them got wet and have swollen and venear is pealing. My question is, if I build new cabinets to the exact measurements of the originals out of mdf will this affect the sound quality? Also, were can I purchase replacement tweeters one is damaged. I would like the peerless version if still available. This is my first post so go easy and thanks in advance for any help/advice given.
