A surface mount ring assembly for loudspeakers which comprises a 'hard' ring in which the speaker is secured. This hard ring is, in turn, secured to a resilient or 'soft' ring which soft ring is secured in the wall opening. The soft ring has a durometer of between 30 to 90 and a dynamic loss modulus of 10<10 >Dynes/cm<2 >at 100 to 1000 Hz. This effectively isolates the loudspeaker from the resonant frequency of the structure in which the speaker is secured.
