4. Speaker System Model: SS-H2500
The enclosures of the R&L channel speaker were partially damaged at the rear due to water absorption, as they were made of MDF board. To replace them, I built two new enclosures using plywood. Additionally, since a 2-inch paper cone mid-range speaker was unavailable, I opted for a normal 2-inch, 10W speaker. I also upgraded the piezo tweeter to a dome tweeter.

Fabrication
To achieve an original look, I fabricated the front side of the enclosure by using material from a plastic office file/folder after applying two coats of black matte spray paint.
My Sony MHC2500 HiFi system restoring—final look.
Restoring the Sony MHC-2500 HiFi system has been a rewarding experience. The new enclosures now closely match the original design while offering improved durability. With upgraded components and a bit of creative fabrication, the speaker system retains its classic look while delivering enhanced performance. It’s exciting to see this vintage system come back to life with a blend of originality and thoughtful upgrades!
