## Description

Review: Small, works - Should have read the dimensions, smaller than I thought. I used this with the same brand ultrasonic tone thing that it’s meant to be used for. Together the volume is sufficient for a medium room but outdoors maybe 20ft. Not amazing. Speaker definitely gets up there in frequency, just wish it was louder with this setup, and larger. This is my first peizo but I noticed the cone is plastic, not that carboardy-fabric stuff like with real speakers. Makes me wonder if I can use it outdoors without a cover since it’s like all plastic.
Review: Great speaker - Super clean and responsive
