Hey Gar The 409 Altec is a single speaker, if you can find another it would be a steal at my price of $10, sound is nice, bottom end good, needs help on the top. The Heathkits are a pair. The picture shows them mounted on a couple baffles I had on a back loaded horn cabinet, good bottom end, not impressed with top end so I use a 1st order xover and add a tweeter and they sound very nice. The Telefunkens are by far the best sounding single speaker I have used. Good performance all around, very smooth with solid bass and top end. Imaging is excellent great speakers. All of the speakers were used in a cabinet. The Telefunkens came out of a console I purchased from an elderly lady who said she used the radio maybe twice in 20 years and they look new. If interested let me know and we can do some price talk, but cheap is the order of the day.
