Eminence Beta 12LTA. near new. $80/pr. Great mids for 12". "Afterburner" for boxed, good to mate with sub for OB.
Coral Flat 6B. One whizzer is off, comes with so can be reglued. $60/pr. Smooth and creamy.
Tannoy CMS65 ICT. The drivers from a ceiling speaker unit they make. 4 ohm. $50/pr. near new. Good, easy listening, 0.5 ft3 sealed or ported.
8" poly woofer, rubber surrounds. Meniscus Audio Magi WR0838R. $80/pr. Imo cleaner and better bass than Vifa poly's. 2 way at 2000-2500, 3 way or sub. 1 ft3 sealed, 1.2-1.5 ported. Surprising bass quality.
Pioneer 4" Alnico. nos. $40/4 of them. I haven't played with these besides a check to see if they work, they do. They do not have a typical surround, are just the cone material pressed and adhered to frame. So would think best considered a lower mid-treble driver?
Philips 15", alnico. $75/pr. Reconed, foam surrounds. They work fine, didn't get around to experimenting. Came from a 3 way retro. (maybe groovy with pioneer 4's in a two way?)
Madison Knight 15". These are good OB bass drivers, ~ 88db (estimate). Tried with FE127e's and had to pad the 127's a little to match. They have very nice tight bass, imo best of all 12-15" drivers I tried this way. Imo a real sleeper. Made for bass player speakers. Qts. 1.0.
Thanks, Don
