Hi everyone on the Altec post, i have a pair of Altec 604-8k speakers in Altec cabinets. The issue i am having 1 driver sound the way it should, the 2nd driver has very little bass very thin and flat sounding. i checked the phasing all good, i changed over the crossovers fault still there. i checked the HF positive and negative all as it should be, the DC reading of the LF speaker number 1 is 6 ohms the 2nd is 7 ohms. i bought the speakers 2nd hand few years back of my boss who use to run them very loud. my thoughts were i may have a burnt voice coil, or the magnet has lost it gauss . has anyone else had the same issue and or is there anyone here in Australia with a 2nd driver etc. my work has the re-cone kits from the USA so the drive does not have to be working. thanks any hope you guys can help doing my head in
