I am considering using these speakers for my DIY home theater system. I will buy them from Parts Express They have an 8" # 296-136 on sale and I may purchase 8 of these and build MTM setup using the Audax textile dome tweeter #276-152. They will be floor standing except the center. I could use a crossover recomendation for these if anyone may know what I could purchase. I don't know how to build one.
