I just purchased 4 Aura bass-shakers, and have been reading previous posts to figure out how in the world to hook them up. From what I understand, the proper connection requires a Y on the LFE (I only have 1 sub output), and an extra amplifier (I am going to use an old Dolby PL receiver). My question is, isn't there some type of Signal Loss by Y-ing the LFE output? If not, then am I correct in my connections? I guess I will daisy-chain them together in pairs and hook them up to the speaker terminals. Also, where can I get a 50 hz low pass filter? Been looking, but to no avail. Thanks in advance for the help!
