SRX828S is a dual 18” subwoofer for concert, touring, or installed use. Featuring a wide stance for splaying top boxes, indexing feet for stacking in both the standard and cardioid position, and a 141dB max SPL, the SRX828S is an ideal solution for musicians, bands, and DJs, concert use, public speaking, or installations such as performance venues, corporate spaces, educational facilities or houses of worship.

I'm completely satisfied in my choice to add another one of these guys to my inventory. These srx828's sound great and responds well even while being pushed AND once powered correctly.



So Much BOOM!


Possibly the best value 218 on the market. So much boom and enough cut to break through any mix. If you need a powerful passive 218 this is a great cabinet. *Hands on review by Christopher M. from store 57 in Indianapolis.
