Red Part No RYB0103.  Foster Part No: 426539. 

0.5W Speaker unit, 4Ω, 36mm Diameter.  

Manufactured by Foster, and used in a high number of two way radios this 36mm diameter speaker has a mylar cone for water protection and is slim.


This speaker will also fit the Fox RX plus, fishing alarm unit, although we recommend the higher impedance unit RYB0101 as this speaker is 4Ω rather than the original 8Ω unit in the receiver and although the RYB0101 is a 16Ω speaker and will slightly reduce the highest volume setting, it is a robust speaker.

Once this stock has run out we will not have any more.
