I was thinking of getting some Aura Bass Shaker Pro's and hooking them up through an old Pioneer receiver of mine (251x-r or something) like I've seen some of you describe on past threads. However, I dug out the old manual for this receiver and the specs read: 50 watts per channel at 8 ohms; ranging 40Hz to 20,000Hz with 0.8 THD. I think the wattage per channel is OK for these, but how about this 40Hz range? Does that mean I won't feel anything from the shakers if the LFE is below 40Hz? Thanks in advance.
