Loudspeakers perform best only free-standing or flush-mounted in a boundary
Evidence
In the case of flush mounting the speaker in the wall, the result is slightly different. Now the effect of the mounting surface extends to very high fre quencies and therefore the number of surfaces that affect the low-frequency response reduces to two. This means the maximum low-frequency rise becomes 6 dB and the optimum ratios of placement change. — David Howard, Jamie Angus, coustics and Psychoacoustics, 2194 (

- By placing the speaker carefully, with respect to the boundaries, one can eliminate some of the variation in the response. However, one still has a 9 dB rise in response at low frequencies. This is well known and the 9 dB rise at low frequencies is inherent in operating in an environment with three boundaries. In general, the lowfrequency responses of loudspeakers designed to be placed close to boundaries is tailored to compensate for it. — David Howard, Jamie Angus, coustics and Psychoacoustics, 2193 (
