As ThomasW says... we can't tell the difference between 10hz and 15hz (did I get that right?)... looks like you don't even need an IB. 
That is amazing response! |
Hi Sonnie
Do not confuse a steeply rising response curve from a reflex enclosure with what an IB can do in terms of incredible clarity and a real sense of brute power unleashed. My IB plays tunes on organ pipes that the big SVS can only pretend to know. It's never enough just to play low frequencies at high levels unless it is done without unwanted distortion components muddying the effect.
Since the infrasonics are inaudible you can only feel them. The human physiology is poorly adapted to judging the frequency of infrasonics. Provided it makes the room rattle you have nothing to really lock onto. In my experience a 15Hz sinewave is no different from 12 or 10Hz Hz test tone unless your windows, doors, walls or floor begin to resonate in sympathy with the acoustic energy generated by the sub. I can sense nothing at these frequencies myself. There is not the same feeling of pressure in the head that I usually get up around 18-20Hz. At 15Hz and downwards the windows and doors start to shake violently and that is the only warning that something is happening.
Here the SVS presently seems to have the edge in getting our boarded floor vibrating so hard it feels competely soft. I'm hopefully working towards this same effect with my IB using Thomas' and other Cult member's help and recommendations. It can only be a matter of degree since the IB keeps on going where the SVS falls off a cliff at around 15Hz.
