Why this accessory matters

Standard speakers in model locomotives can sound thin or limited in bass response. An enhanced bass speaker improves depth and realism, making engine sounds more immersive and closer to full-size railway acoustics.

How to use it

Install inside a compatible OO scale locomotive, connect to the HM7000 decoder output, and secure in an acoustically suitable enclosure where possible. Ensure correct wiring and placement for optimal sound projection.
