I have been aware and looking for Altec 604 and 605 speakers for several years. Finally I was offered and purchased one pair of 604 - 8G with Stonehenge III crossovers and one pair of 605B with N-1600B crossovers. I want to either purchase some Altec cabinets or build my own for one pair of speakers and crossovers. I've looked these over and preliminary testing indicates that these speakers and crossovers are fully functional and in good condition. Let's say i am only interested in using one pair of speakers. Which speakers and crossovers do I put into service?
