Progressive spider provides better control at excursion limits than does the more commonly used linear spider.

    You Will Not Upset
    I have 2 of these in a sealed box and it bumps. I recommend this for anyone on a budget. You will not be upset. It would sound awesome in a ported box but you can't complain with it in a sealed box. It's simply great.
