Overview

This Yamaha S4115H is a vintage horn-loaded speaker cabinet built during Yamaha’s early professional audio era, known for rugged construction and efficient, high-output design. Featuring a large horn-loaded configuration with an integrated high-frequency horn and level control, this cabinet is designed for strong projection—ideal for PA use, rehearsal spaces, or even unique studio and vintage rig applications.

Rated at 100 watts continuous program with an 8-ohm nominal impedance, this cabinet pairs well with vintage or lower-wattage solid-state and tube power amps. The horn design helps deliver excellent midrange clarity and vocal presence, making it especially useful for live sound or retro PA setups.

This is a great piece for someone looking for vintage Yamaha PA gear, a unique cab for a retro rig, or even a conversation-starting studio piece.
