Collection: Energy

Energy Speaker Systems built a strong reputation in Canada and the US for well-engineered bookshelf and floorstanding hi-fi, and models fitted with the ESM4 mid/bass driver and similar units are still delivering solid sound decades on, provided the foam surrounds have held up. Foam perishes with age and UV exposure, turning brittle and eventually crumbling away from the cone edge, which causes buzzing, air leakage and a noticeable loss of bass tightness. We stock foam repair kits for Energy drivers across the common sizes, from 5" up to 12", covering the OD/ID needed for the ESM4 and equivalent models.

Each kit includes two surrounds, T7000 glue, a brush and full instructions, enough to refoam a stereo pair in one go. It's a cost-effective way to bring tired Energy speakers back to their original performance rather than replacing the whole cabinet or driver. If you're unsure whether this fits your speaker, drop us a message with your make and model and we'll confirm before you order.
