This is a pair of used Dalesford D100/250 10 inch woofers from a Fried Model H2 woofer. One driver has a crack in the plastic cone that has been repaired, see photos. They both play okay, and DCR measures 6.15 and 6.40 ohms, and both have a March 1978 manufacture date. These woofers were used by Irving "Bud" Fried in his Model H2 and Model T transmission line speakers. This pair is from a Model H2 woofer and the cabinet (in fair condition) is also for sale for local pickup only, contact me for details. For shipment, these woofers will be bolted together to protect the cones as shown in the last photo. Dalesford datasheet included in the photos.
