Oh really?They look far too small for the space you want to fill with sound
The dimensions are 12 x 6.5 x 9.25 inches (HxWxD), which is considered large for a bookshelf I think. Also I read that:
"The maximum output is specified to be 109dB at a distance of 1 meter from the stereo pair", so I thought this would be plenty enough.
What makes you think they are too small for the space?
