REDLINE EROM Surround
Less -

EROM (Extended Range Of Motion) surrounds, pioneered by DD in the early 90’s, allow our subs to have higher, more linear excursion with more cone area than subs using wider surround profiles. Simply put, this surround design allows our subwoofers to make more and better bass than other subs out there. In fact, we like this surround style so much that some variation of it is used on all levels of our subwoofers. The REDLINE EROM surround features new signature aesthetics including a red accent line pressed into the surround and an embossed REDLINE logo.
