Pair of Altec 420A (Y) 15" alnico biflex drivers used in altec Santana and popularized by Lampizator in his monster P24 Project.( The designator Y comes from the version used with tweeters attached to the front basket which were removed) Like Lampizator I replaced aluminum dust caps with GPA (Great Plains Audio) sourced paper caps to tackle HF hash of aluminum dust caps. Since I don't have a room for big OB's (too narrow) I never built the speakers. I was holding on to drivers but even though they are becoming increasingly difficult to source they do pop up from time to time so there is no reason to keep them indefinitely. I can send via cheap courier service to Eastern EU and most of the Western EU via Polamer shipping for ~$100. It will take 3-4 weeks and no tracking unfortunately.I will provide TS parameters . Drivers are in very good condition. $450

Nice drivers, they are woofers or full range drivers?

[klamka]

They are 15" fullrange drivers with QTS around 0.7 or more and 21 Hz Fs . The are used in Santana fullrange with adjacent tweeter (cap crossed ) . Lampizator is crossing them at 1.2K Hz to oval vintage radio mid and RAAL tweeter . I had them in JE Labs Open baffle and they are very good . My friend has a huge OB with a pair in each.  Motor and the basket is the same as in 416.
