Collection: Sound Dynamics

Sound Dynamics was a well-regarded Canadian speaker brand through the 1980s and 90s, and models like the S-15, 120-S, SMT-1000 and 300Ti built a loyal following for their value and sound quality. These speakers are known for a distinctive orange-red foam surround, and while the colour has held up, the foam itself hasn't - by now it's typically brittle, cracked or crumbling, leaving the cone loose and the bass weak or buzzy.

We stock Sound Dynamics repair kits across the full range of sizes these models use, from 8" up to 15", including colour-matched red foam options so the repair looks as close to original as possible rather than an obvious foam-coloured patch. Each kit includes two surrounds, T7000 adhesive, a brush and full instructions. If you're unsure whether a kit fits your speaker, drop us a message with your make and model and we'll confirm before you order.
