This FR (Full Range, Flat Response) version houses a precious, max. 130W SICA 6 D 1.5 SL double-cone Neo speaker. Equally at home with acoustic guitars, keyboards, harmonica, violin and even human voice, it also serves as a compact but loud enough personal/studio/stage monitor for the modeling amp/IR community. Use a pair for stereo, or in wet-dry setups together with larger TOOBs.
