For difficult installation situations with little available space, especially in N-gauge, we recommend our miniature loudspeaker with a footprint of just 10mm x 12mm. This speaker was selected by our audio engineers after extensive testing because it offers a good compromise between acceptable bass reproduction and volume. This ‘dwarf’ produces an astonishingly high sound pressure level - when combined with the appropriate sound chamber. The set includes four sound chambers of different heights, resulting in a total height (with mounted speaker) of 11mm, 8mm, 6mm or 5mm. Choose the largest sound capsule that you can accommodate. Adhesive tape is provided on the speaker itself for simple, airtight mounting. The solder connection is made via a short piece of flexible printed circuit board.
