Feature(may vary by option.)

●This bass reflector duct is a special bass reflector duct that has been tapered like a horn shape. This bass reflector is used in the Sound Kobo Z speaker/speaker kit. The speaker you are using is "Product Description"
●The biggest benefit of this tapered bass reflector is that it reduces the habit of being called "bass reflex odor" even when the bass reflector has to be used for a long time, and is expected to improve low frequency response resolution
●Duct can be easily cut with a saw to change the resonance frequency. The instruction manual includes a spec sheet (with calculation), which describes how much resonance frequencies will occur when you cut this bass reflector by 10 mm (10 - 45 L). People who make their own speakers can understand the resonance frequency estimates without having to do troublesome calculations
●The appearance and design of the product is very beautiful when installed, and is not as good as it is used in market speakers
