Miniature speakers may not show their performance without a rear cavity. These enclosures provide a controlled volume for testing.

Same Sky has introduced three speaker prototyping test enclosures that give engineers and product designers a simple way to evaluate miniature speakers with an acoustic cavity of approximately 1 cc. The enclosures provide a controlled rear volume during testing and can also be used as a starting point for a final product enclosure.
The three models are designed for different rectangular speaker frame sizes: BOX-1511-1CC for 15 × 11 mm speakers, BOX-1609-1CC for 16 × 9 mm speakers, and BOX-1813-1CC for 18 × 13 mm speakers. Same Sky lists these enclosures as accessories for its miniature speakers in the corresponding sizes.
Audio engineers, product designers, and R&D teams can use the enclosures while selecting and testing miniature speakers for products. They can assemble a speaker with the enclosure, test its performance with a defined rear volume, compare different speaker options, and use the results while developing the product’s final acoustic design.
A rear enclosure can be important for miniature speakers because some models require an enclosure to achieve their specified performance. Testing such speakers without the required acoustic cavity may prevent them from showing their intended performance. The approximately 1 cc cavity in these test enclosures provides a controlled rear volume for evaluation.
Same Sky describes the enclosure as a simple three-part system intended to support quick testing of miniature speakers. The same setup can also serve as a building block for a final product design. An assembly guide provides step-by-step instructions for preparing the speaker and assembling the enclosure.
The company also provides speaker-related resources, including an SPL calculator, custom audio solutions, audio design services, videos, and other technical content. Its speaker enclosure resources cover the role of rear enclosures and design considerations for miniature speakers.
