Hey guys, hoping for some quick input. I saw that Parts Express has the Aura Bass Shakers on sale and may order a pair Friday depending on what you folks say...here's my question: The shakers are 25w RMS/ 35w Max (4 ohms) , could I use my B channel on my Yamaha RX-V496 (70wpc 8ohms) to run a pair under my main chairs? All my speakers are set to small since I have a pretty good sub, so the reciever should be able to handle the 4 ohm load very well, I just want to know if it will be TOO much power...and if this is the case, could I run 2 shakers per channel to help out? Final question: Can u "hear" the shakers? I know they are meant to be tactile, but I don't want to be adding "unwanted noise" to my listening enviroment unless its a good thing. Thanks.
