Hello everyone. I need help identifying my lascala speakers i got at an auction recently. pic attached.there type is LS-BLS and serial number is 11R-908. Any information would be great , as i know nothing about them. thinking of selling them on ebay. they have many serface scratches and one chip in them,they r very sturdy and sound great. also does anyone know how i would go about cleaning the crossover up ,should i use just canned air or is there something else i could use on them ?
