hemp cone speaker. Hemp is a denser, stiffer material than traditional paper pulps, and

cap. More mass will have an inverse effect.
Also, take notice of the material. A cloth,
screen-type cap is commonly used on guitar
speakers and sounds relatively transparent.
Hard paper caps sound brighter. Felt caps
add warmth and smoothness to the highs.
The frequency response graph is also a

levels (figure 5). A speaker that exhibits
a variance of peaks and dips will typically
