So after years of pontificating that it doesn't matter where a sub is located (move it around until you find the sweet spot, dont get hung up on symmetry / visual appearance) I was sitting at my desk listing to my recently bought ADAM A3X's and the just arrived Sub 7 unit which was of course placed dead centre and front facing...

) and still wasn't perfectly happy with the tone, (I used my Sennheiser HD580 headphones to A/B with and tweak HF controls on the ADAMS) so I wondered, sub - can you kick it? Yes you can.
Luckily I have a smooth (fake) wood floor under my desk so I kicked the sub around from side to side and found that it sounded best facing left with the long side of it parallel with the sliding door / window.
Great!
Also the little sub volume and crossover adjuster remote controller is VERY handy for fine tuning set up.
So its ugly seeing the cables dangling out from the side! (but I can obscure that with the electric heater under the desk I use in winter.)
Ah! Playback bliss!
Sounds lovely!

Actually - last time I had a sub set up (Genelec 1031A's + a huge sub) - I liked that positioned sideways against the facing wall too
