Hello All,
My grandfather is hard of hearing and found out how to adjust the cv's.Well he likes the rumble sound of the Alco  s4 .He turns it up to around max. Sound really good ,but when the horn is blown the speaker cannot handle it all together it cracks and then gets real tinny.We replaced the speaker 3 times so far.Was thinking I could find a higher watt speaker the same size to fit in the speaker enclosure ,but not exactly sure my measurements are correct. Does anyone know what size speaker is in it exactly so it can press fit in the enclosure correctly?
  Thanks.
