The DynaBox Speaker Enclosure is an innovative acoustic solution designed to significantly reduce unwanted sound transfer by containing the reflected sound energy produced behind a speaker. By enclosing the rear of the speaker within a sound-insulated chamber, DynaBox helps minimise sound migration into adjacent rooms while enhancing overall audio performance.
Its flexible, compressible design allows the enclosure to fit through a 165mm speaker cut-out (or larger) before expanding back to its full shape once installed. This makes the DynaBox ideal for both new installations and retrofit applications, where controlling sound leakage from existing speakers is essential.
Internally, the enclosure is lined with high-density acoustic foam on all four sides, with an additional rear foam insert that helps absorb speaker back-wave energy. This reduces distortion, improves sound clarity, and creates a cleaner, more accurate listening experience. The enclosure also provides added protection for the rear of the speaker by acting as a barrier against moisture, dust, and debris.
Suitable for use in domestic, commercial, and marine environments, the DynaBox offers a simple yet highly effective way to improve speaker performance while reducing unwanted noise transmission.
