I have a Kicker S15D (circle model) and the spec sheet recommends a 1.5cuft and 50% polyfill do I have to use polyfill ? and doesn't the use of polyfill reduce SPL.

Because really I don't want to use any

it will effectively boost volume the speaker sees which will lower the frequency the box can hit plus it will add sq to the sub and (maybe spl but not always)

Do you think I would gain more SPL without the polyfill or with it or should I just use some dynamat inside the sub box would that change anything
