I know there's a lot about this already, but I couldn't find any satisfactory answers so far. I play a 2nd half 70-ies Ampeg SVT through my own made 2x 4x10's. High quality arctic birch plywood. Exactly modelled after a squareback, just cut in half. I use a combination of SVT 32 ohm reissues: Eminence Legends, Electro Harmonix and 2 Jensen Mod's for a bit extra highend - like suggested on this forum. Main instrument is a pre-CBS P-bass with flatwounds. I live from playing music. I was actually pretty happy with my sound, although I always kept on looking for more warmth and nicer more airy mids. Just a year ago I completely by coincidence ran into 8 totally original '78 (all from week 35) Eminence squaremagnets for a really fair price (400€ (say 550$) so I had to buy them. Coils moving properly. They all measured like 25 ohms which is supposed to be good: so everything cool. I put them in my cabs and used them for over half a year on a wide variety of stages and for recording. They inmediately struck me with a totally vintage vibe: they sounded superwarm, creamy and very deep. The highs are way more natural then on the reissues. Guitar for instance sounds awesome through them. But I started to miss the tight punch of my reissues. The old speakers just don't seem to be lively. They don't seem to cut through on stage and have mainly a lot of boom without too much articulation. I guess 'muddy' would be the proper word. Is this something typical for the 70-ies speakers? Would the older CTS alinicos sound tighter? Or would reconing help (although everything seems to work properly). I don't run into old cabs too often I'm affraid. I played through some 'towel-bar ones' a couple of times on festivals, but you never can tell what's in there in such short notice. Maybe I'm just used to more modern tighter sounds although I consider myself totally 'Old-School' and I dislike almost all more modern cabinets. I've put my reissues back in and everything is back to normal again. The question now is what to do with the beautiful old speakers! All thoughts are appreciated.
