Fisher Stereo Speakers model#ds810

Not sure about that exact model but if i had to guess i would say mid 1980s. Are they the ones with the 15 inch woofers? If so i had the same ones and i had bought them brand new in 1986 and they came with a full rack system that i spent about 600 for and that was in 86 i dont think they will be worth much but they do sound good if they are the ones im thinking of. What i had done with mine though was change out the tweeter and mid range to a lil higher quality but the woofer pumped out some serious bass. Hope that helps
