Sega Blast City Speakers
The Blast City is equipped with a pair of speaker boxes ( sega part # 130-5156-01 ) each containing
- 2 full range speakers ( Toptone F17E4U01-1 )
- 1 tweeter ( Toptone FH25G13-9 )
The foam around the F17E4U01-1 will rot and fall apart over time, but can be refoamed.
A revision was made for other sega machines that appears to be the same ( 130-5156-02-91 )
