    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! [​IMG]

    There is no signal loss, it is just weaker. It doesn't make any difference as you are sending it to an amplifier before the sound is reproduced.

    Hi Derek -
    I just picked up a pair of the Aura's from Ubid. I bought a used NAD 2240PE 2-channel amplifier from a local audio store to drive them. I Y-ed the LFE output from my receiver -- as you are thinking of doing. The LFE level did drop some, but I just increased the gain on my sub to compensate.
    I found an electronic 3-way crossover for about $30 bucks over at RadioShack. It has low-level inputs/outputs, selectable x-over frequencies, and a bass gain control. The downside is that it is designed for a car stereo system so I had to buy a 12 volt power supply for about $15 bucks too. Come to think of it, I probably spent another $10 bucks on misc. cables and splitters as well.
    SIDE NOTE:
    I'm not sure if the manual covers it (I guess I should read it), but I found that mounting the bass-shakers to fire vertically works better than if they are mounted to fire horizontally.
    At any rate, good luck and have fun with your project! I know I did.

    So, there is some signal loss, huh? Any idea where I can buy an outboard crossover so my auras won't be over-zealous? (online?) I hear that is basically their only problem. I haven't heard anything about mounting them vertically or horizontally - which is better?

    If you buy the Aura Interactor Vests and strip out the transducers, they come with their own amplifier, complete with level and rolloff adjustments.
    The last batch I bought were $5.50 each.

    Any idea where I can find these Interactor Vests? What are they, and how many do I need...........do they work as well as an extra receiver, or better?
