Below text compose by Mike Bruno for the sale of these drivers. We are not re-building them; Mike is. All after sales support will be handled by Mike by his terms on these refurbished drivers. PM: woofercooker – or preferably – e-mail: idblbruno@hotmail.com for inquiries. ---------- I will be selling Sundown’s inventory of SA-8s that have either failed quality control testing or were returned by customers. Each of these woofers were tested by Jacob and found to have a defect in the coil alignment or other cosmetic / performance defects. I will be refurbishing these woofers with the latest OEM SA-8 parts and reselling them to the public. Many of these have never been mounted or powered other than to check for coil alignment or other defects; some are warranty returns so will be used motors, though. Buyers will receive 100% fully functional refurbished Sundown Audio SA-8 woofers. As I said, some of these have been used before so there may be some signs of use on the motors. The baskets and soft parts are all guaranteed to be brand new. Available in D2 and D4 coils.
