Offering for sale these ISOPHON Speaker Components: $250 for the complete lot.

These vintage pieces - made in Germany - probably in the late 1960's to early 1970's, are highly valued and fairly scarce. I would prefer to sell them locally, but will consider packing & shipping to buyer (at additional cost). I'm open to selling individual drivers in pairs - prices as listed accordingly. Please inquire for more info or with any questions you may have.

1) A pair of PH2132E drivers: ($120) Elliptical woofer in 21x32cm frame with Coaxial 10cm tweeter. Woofers measured 2.76 & 2.71 ohms DCR, resonant frequencies of 60 & 62 Hz. (Mfg's spec. is 55 Hz.) Tweeters measured 4.44 & 4.75 ohms DCR. Crossover capacitors replaced with selected upgraded parts. Play tested & sounding fine.

2) A pair of P30/37A 12" woofers: ($120) These 30cm units appear identical in construction except for a difference in the rear magnet cover: One has a formed aluminum cover, and the other has a slightly deeper molded plastic cover with spacers on the magnet structure for attachment. Measured 2.64 & 2.66 ohms DCR, resonant frequencies of 59 & 47Hz. (Mfg's spec. is 45 Hz.) I have measured the T/S parameters & have .wdr driver files for WinISD available on request. Play tested & sounding fine.

Components from a pair of DHB 6/2-10 Mid/High driver assemblies:

3) 2 pairs of 10cm tweeters: ($40/pair) These look very much like model HM10C units, but being part of the stated assembly - they have no individual ID markings. Measured DCR values between 4.42 & 5.66 ohms. Tone tested & seem to be working as they should.

4) A pair of mid-range drivers in plastic re-entrant horns - approx. 12cm ID mouth opening x 17cm long: ($40) Measured 3.18 & 3.27 ohms DCR. Tone tested & seem to be working as they should.

5) A pair of mounting plates, hardware, crossover components, & input terminal plates - all AS-IS - from the DHB 6/2-10 assemblies & the NORESCO NE-581 cabinets which the woofers & mid/high assemblies came out of. ($20 for all the bits shown)
