Hey, I dont have very high end system as im just a poor student newly entering the whole AV world, but im sure you guys wont begrudge helping me out. I managed to get hold of a 'Aiwa AV-D58' for free. And my front speakers are a pair of old 'Technics SB-4000 2way', which i simply love the sound of. I bought a little new speaker wire, 316copper strand from richer sounds nothing extravigant. Anyway i finally got round to actually opening up one of the speakers to have a look inside, theres is tons of 'padding' of some sort in side, whats this for? The actual wires inside the speaker are fairly tiny, now should i consider replacing this wire? do think rewiring the actual speakers will show much improvment? The sound from the speakers is still good, but the boxes are old and battered, so i want to make some new boxes for the driver units. Can anyone give me a link to a site with good speaker box designs? any tips? Thanks!
