K 28.40 - 8 Ohm

Art. No. 2945

2.8 x 4.0 cm (1.1" x 1.6") miniature speaker with paper cone and rectangular plastic basket. Small dimensions due to neodymium magnet. The excellent interaction between the different components achieves a very linear frequency response. Connection via soldering points on rear side.
