Availability: Out of stock
$ 149.99


Get that “Big Bottom” with the HIPPO Subwoofers When Massive Audio designed the “HIPPO” Series Subwoofers we had one thing we wanted out of the design. No junk for a trunk just a subwoofer with a “Big Bottom.” All three Hippo Series subwoofers 8”, 12” and 15” are truly giant works of art that can slam! These big bottomed boys use 3” over sized voice coils that hold 4000 Watts of power, extra deep diamond polished cast aluminum baskets, double stacked Strontium Magnets and Kevlar Fiber Reinforced Non-Pressed Paper Cones that has a industrial machined stitched edge right into the cone’s surround for added strength. To feed a 2013 HIPPO Massive Audio recommends 500 – 2000 RMS of raw power. You can cage a HIPPO in a sealed box as small as .375 cub. Ft for Hippo 8, 1 cub. Ft for the 12” and only 2 cub ft for the 15” or you can let them relax in a ported box for even more of that “Big Bottom ”. Massive Audio “HIPPO” Series is Big, Bad and Beautiful”.

Ask a Question
  • What is the mounting depth for the hippo84 and what is a recommended ported box for a single cab 1999 ranger.

    The HIPPO84 is 5.04" deep. Optimum box would be 1.1ft3. If you open the Manual on this page it will give you all the mounting and box specifications if you need more info.

  • What's the warranty for a HIPPO84-8?

    Please review our warranty policy https://www.massiveaudio.com/pages/warranty-policy. Thank you and stay safe.

  • I am running a db 3000 watt amp and want one 8 inch sub could you help me please

    Hello Daniel, Thanks for coming to Massive Audio.  Is that 3000 rms wattage?  Asking as that is a ton of power for a single 8" subwoofer.  Do you have space for a larger sub by chance?


  • What is the magnet diameter?

    magnet diameter for HIPPO 8 is 6.2"

  • are these now discontinued in favor of Hippo xl 84

    No, we have both models avaiable.

  • Is there a protective cover or grill made to fit this sub?

    So sorry our subwoofers do not come with and we do not make any grills or covers for them.

  • Can two of these subs be wired down to a 1 ohm load

    Yes any 2 x Dual 4 Ohm woofers can be wired to 1 ohm if you connect POS to POS and NEG to NEG
