Before I ordered 2 of the cheaper variant of "Body Shakers" which fiberglass oscillating elements had (allegedly 100W)
but these do not come closer to this product !!
I can be seen on the pictures, the "Body Shaker" screwed to a plate under my bed (3).
The basses are extremely tired and defines outstanding. If you turn the volume it takes a downright breath.
I really did not think that a single unit, even for this price / performance -mäßig good price can convince so.
I use the Reckhorn BS-200 on a normal stereo amplifier from Pioneer, which serves as a feed receives the subwoofer signal my 5.1 receiver. So I can save a low-pass filter and it works just fine.
The Bass Shaker is also very well made and makes a very sophisticated look. Another plus are the pressure plug, what plug and play convenience. My Home Theatre System has been usefully supplemented with this unit and Music, Movies & Games now benefit from the bass impulses of the body shakers. To get a comparison: If you are the Bass Shaker approximately 60-70% of the maximum power in music or movies, the bass pulse effect is already comparable to a subwoofer Beyond the "real" 500W brand - for 57 has thus a cost-Class Alternative !
Strong buy recommendation!
