waveguides as far as i can tell are designed to equalize the power response.
for example if we are talking about a typical 2-way speaker with a 7" midbass and 1" tweeter then there will be a discontinuity in the power response around the crossover. because just below the crossover the woofer is quite directional and just above the crossover the tweeter is radiating in all directions.
on the other hand if you use a waveguide like this:

it will flatten the power response around crossover frequency because it will make the tweeter equally directional at those frequencies as the woofer.
since we don't listen inside a black hole any energy that leaks into the room ( at any angle ) is likely to find its way into our ears. equalizing power response thus i think makes sense if you can do it without compromising the response on the listening axis.Rerurn to Romy the Cat's Site
