I saw a thread a while back about a fellow named Todd Welti, that did a study on optimum number and locations for subs. http://www.harman.com/wp/pdf/multsubs.pdf . The results were that two were good and 4 were better. With that in mind, how do you send the LFE from your receiver/pre-pro to 2 or 4 subs at a time? I am picturing a medusa looking cable that splits from one to 4 and going to the 4 subs. Is that how you would do it if you only have one LFE output on your receiver? Or do you daisy chain around the room? What if you had separate amps? That would get to be lots of cables. Like the article says, you would get lots of output, and pretty smooth response. Anyone tried spacing 4 subs around their room? If so, what are the results?
