"3 Dimensional Sound"?


Many speaker ads boast of "3 dimensional sound" from their product. I can easily hear the width dimension (based on left and right panning) and a sense of depth. But can you get height information from two speakers?

I agree with the crowd. In my experience with thiels(dynamic drivers) and the correct absorption materials correcting the 1st reflection points (sidewalls, floor, ceiling) behind the speakers with bass absorption in the corners and on the front walls; the thiels disappear in the room. My thiels required considerable setup. My source Cd players also made a huge impact on the staging too. Listing to levinson and wadia equipment of the past put a 2 dimensional sound. With the best theta processor at the time there was a huge 3 dimensional stage.

My electrostat experiences range from maggies, martin logans. In a professionally setup sound room. The speakers disappear and so does all staging and points of reference. It’s like listing to a pair of reference headphones.

Some of the best reference recordings for staging can be had from

The DIY asylum has tons of diy bass traps acoustic panels. Jon Risch has a website of some very basic acoustic diy projects that work wonders and are inexpensive as well reference books and web-postings from ASC etc…
