The Sonance SM55 SST Surface Mount Speaker is the perfect solution for those who demand quality sound but cannot use in-ceiling or in-wall speakers. In the SM55 SST, Sonance engineers have created a speaker that sounds great, yet is decor-friendly, easy to install, and do not require a mounting hole. A one-step paint process saves time compared to traditional ﬂanged speakers.
The low-proﬁle surface-mount design is ideal for installations that cannot accommodate in-ceiling or in-wall speakers. Installation is extremely simple: Connect the mounting plate to the speaker wire and screw it to a junction box in the mounting location. The mounting plate rotates, allowing the SM55 SST to be aligned with lighting ﬁxtures or other decor features after installation. For installations without a junction box, the speaker can be attached directly to the mounting surface without using the mounting plate.
