1000+ Head-Fier
What is the big deal with using the control box anyway? I don't mean that in a challenging way, I just don't know how you're using the control box. The KEF M500 is a nice headphone. I only sold mine as they weren't internally balanced and I wanted the balanced option for the Onkyo.
First, I still love my gorgeous sounding KEF Audio M500 on-ear headphones; these will still be my primary portable cans with my Onkyo DP-X1, unless I get cash for the Audeze SINE (simply because I already have DHC Zync cable, and that should work with the new SINE headphones too).
Second, the SubPac S2 is not an amp, DAC or any kind of audio device you've heard of.
There are two models, one you can wear (M2, very recently released, an update over the M1), and the S2.
With either model, the control box for each adjusts the intensity (mechanical power) of the device to let you FEEL the bass on your back.
The S2 I have (and is used by artists, DJ's, studio's like Abbey Road Studio's, etc) sits on your chair. You then lean your back to it.
The control box does two to three things.
- It receives an analogue input from an audio source, and takes only the sub-frequencies. This is then converted to a mechanical response using miniaturised actuators. Think of cinemas with vibrating chairs. This is the SAME TECH, miniaturised!
- If you plug your headphones to the output of the control box, the control box will pass the analogue audio stream (supposedly) unaffected out via 3.5 mm SE.
In my case I use amps with two outputs, one signal to the control box but I directly connect my headphones to the amp; this way I can have a cleaner signal.
- Or, you can Bluetooth an audio source to the control box and then use it's headphone out. I've used this once as a test, never again as it's of no use to me.
The control box is a central part of the SubPac S2 seatback tactile bass system.
