Scale Sound Systems AHRR-UNI1 Athearn Roundhouse/Athearn GP40-2 HO Scale AHRR-UNI1-RC1

The Athearn Roundhouse (now branded simply as "Athearn") GP40-2 uses the AHRR-UNI1 speaker. 

More than just a box, the enclosure features Diapasonic Tuning™, which allows the lower frequencies to accurately develop and resonate, clears the midrange of excess resonance and tunes the upper-mid/high response. The speaker uses the factory mounts and no modifications are needed to replace the factory speaker (or install this one on models with mounts but no speaker).

The speaker comes fully assembled and tested.

Dimension: 15mmH x 18mmW x 43mmL
