Offered for your consideration is a vintage PIONEER #25-737A-1 10 inch woofer removed from my HPM-40 speakers, manufactured in Japan. This cast basket mid/bass driver with carbon-fiber blend cone was also used in the HPM-60. It bears what appears to be a 1979 build code on the basket’s rear. So, please have a look at my large photos and read the remaining description to decide if this capable PIONEER woofer should be yours. *Although the listing is written largely in singular to avoid any confusion, two (2) PIONEER #25-737A-1 10” woofers are available at time of this writing. Please choose if you’d like to buy one or both in the quantity field at the top of the listing. The shipping cost will be automatically calculated by eBay checkout. This PIONEER woofer is in relatively clean, very good condition. The sturdy ribbed, carbon-fiber impregnated paper cone is structurally flawless with perfect voice coil cap, but it exhibits some staining as pictured (the first of the two woofers to sell, not pictured, has a cone that is less stained). Plus, the surround is permanent “accordion-style” textile material, instead of the fragile foam used on the early version of this driver, and is urethane-coated for added durability. Also, the sizeable cast aluminum-alloy basket is perfect and there are no chips or oxidation on the large magnet structure. And, the +/- terminals are marked for polarity (red dot = +), measure the standard .205”, and have never been soldered on the spades. Overall, this is a well-preserved vintage woofer. Most importantly, it was tested recently and sounds great with clear, fast midrange and ample low-end. It’s rated down to 35Hz and carries to 4kHz in the HPM-40, so it’s a stout wide-range driver. Plus, I tested its DC resistance at 5.9?, consistent with an 8 ohm nominal rating of the past (it would be considered 6 ohm today). Lastly, the basket measures 10?” across, 11½” at the rounded corners, stands just a bit over 4” tall, and the mounting holes are spaced 7?” adjacent / 10?” diagonal, c-t-c. So, if you have a blown or damaged 10” woofer in your 1977-80 HPM-40, HPM-60, or other suitable model, you’ve found the right listing! Your speaker will be soundest its finest again in no time. Discontinued long ago, and become scarcer every year, it’d also make a smart “rainy-day” spare to have around just in case. As pictured and described, this PIONEER #25-737A-1 10” woofer is offered at a competitive price.
