The XHD speaker system allows for extreme volume capabilities and realistic sound clarity. Simply connect the FOXPRO SP-XHD (8-ohm) external speaker to any FOXPRO game call with a 3.5mm external speaker jack. The FOXPRO SP-XHD is a horn speaker with an added tweeter for improved frequency response. The attached legs allow for more elevation, which creates a better distribution of sound. With the legs folded up, they double as a convenient carry handle. The FOXPRO SP-XHD speaker is proudly made in the USA.
