Since subs produce low frequency audio which is Omni directional there is no need to elevate. In bottom firing subs elevation would be counter productive.
Is Subwoofer Elevation a Viable Option?
I know this topic has had various discussions over the years, but despite a review of past comments, I could not get a definitive answer on its relative advantages and disadvantages.
I run three subwoofers in my two channel system and am very pleased with the results, but some questions keep nagging me.
Because the sub is typically on the floor, along with all the furniture in the room, wouldn't low frequency waves be blocked/diffused a lot. Wouldn't the sound from a subwoofer benefit from an unencumbered dispersion of energy into the room?
Coaxial driver speakers have their "woofer" at ear height without causing issues. Why not ear height subwoofers?
Is it just because subs are large, heavy and require a power cable or are there sonic reasons for keeping subwoofers on the floor?
