Klipsch speaker placement

The Cornwalls are a great loudspeaker. The woofer crosses to the midrange horn at 700 Hz. Thus the woofer carries a large chunk of the midrange. Remember, middle C is 256 Hz. This means the bass requiring long excursions is going to Doppler distort voice which is very noticeable once you now what to listen for. This makes a subwoofer essential for the best performance. This is true of any speaker that does not have a built in sub driver. You will hear people frequently say that adding a sub "opened up the midrange" of their speakers. The added bass is nice also. 

Klipsch loudspeakers should be against a wall. Subwoofers should always be against a wall or in a corner. The problem is matching the subs to the main speakers in time. That requires DSP which most do not have.

Placing speakers against the wall doesn't not affect the 3rd dimension. Your brain can however. In humans what you see can affect what you hear. Always listen with your eyes closed. You will get a much better appreciation of how the system is performing.

Moving the speaker away from the front wall does TWO things. It effects the response of the speaker in the lower midrange/upper bass depending on the distance and it you move them far enough away the first reflection becomes an echo. What you are interpreting as the third dimension is that echo. The third dimension is the realization of the depth of the instruments, a marker of the size of the instrument and there location in space. 

Echoes that you produce are distortion 😂😂🤣😅😏
