Hello, I aploigize in advance if this is in the wrong section, I assume aura shakers can be categorized with subs, LFE and all. I have a standerd 7 1/2 - 8 foot couch, that I am looking to outfit with aura shakers. First question: The only spare amp I have is a old "vintage" Pioneer SX-3700 http://www.classic-audio.com/pioneer/sx3700.html My main reciever is a Denon 1802. Will I be able to split and run my subwoofer out into this older Pioneer unit, to power the shakers? It puts out about 45 watts RMS per channel, and is perfect working order. Second Question: I am looking at the following two types of aura shakers: http://www.partsexpress.com/pe/showd...number=299-027 and http://www.partsexpress.com/pe/showd...number=299-028 Which would you recommend for a standerd size couch? Two smaller one's are obviously less expensive, but will they do the job? Am I better off going for the "Pro" bass shaker with it's higher power handling, or, if I dare, two of the Pro models, one on each channel of the reciever perhaps. I've never had the opertunity to experience bass shakers, so I do not know what to expect, nor how to judge if they are adaquate or not for my needs. Any help you can provide is greatly appriciated.
