- Full range audio tactile transducer (speaker). - Attach behind ceilings and walls (inside) for a truly invisible home theater experience. - No unsightly speakers visible anywhere - these speakers are completely hidden behind your project / walls. - Mount to plywood, fiberglass, or a number of other materials to propagate sound through the air. - Great for a number of projects, including plate reverbs, spas and hot tubs, bath and message therapy applications, museum exhibits, and experimental projects. - Includes 13 ft of wire, mounting disc and bolt.

- For applications that require higher power handling.
- Extended bass response
- Same precision and quality as our 3" full-range tactile transducer.
- Completely weather resistant.
- Use multiple transducers for even higher power handling and louder total output (require additional amp power).
- Includes 13 ft of wire, mounting disc and bolt.
- Compare to other costing 5X as much.
