Massive Audio Hippo XL 15" Subwoofer

Want “Big Bottom Bass?” Well when Massive Audio designed the “HIPPO XL” Series Subwoofers we had one thing we wanted out of the design. A subwoofer with a “Big Bottom.” The improved HIPPO “XL” subwoofers have changed the herd and wants being heard! The upgraded 2K RMS CEA2031 Certified “HIPPO 122 “XL” & 152 “XL” now use 350 Oz high energy double stacked Strontium magnets bolted to a custom milled oversized back plate.

This design helps lower heat buildup in the dual 2 Ohm Black Anodized 3” VC Formers which are using space age Kevlar Spinlace for extra strength! Kevlar Fiber reinforced Non-Pressed Paper Cones that have been stitched in “Red” into the oversized surrounds. The bonded to dual Poly Nomex Spiders carry the stitched hard wired high voltage tinsels leads that are hard wired to pure 10 gage copper speaker wire.
