In the ancient Japanese sport of SUMO the rules are simple. When the Gyoji waves his fan; push the other guy out of a big circle. Massive Audio created the “SUMMO” line of subwoofers with the same goal in mind. Summo Series subwoofers play so low and with such a deep center of force that the competition cannot help but to bow out gracefully.

Let there be no doubt that with Massive Audio you will be the “King of the Ring.”

Ask a Question
  • What is its depth? I need to know the mounting depth so we can check if it fits in the vehicle (Hyundai Veracruz) which has an existing subwoofer that I'm planning to replace. Thanks.

    The SUMMO64 is 4.76" deep. If you open the Manual on this page it will give you all the mounting specifications if you need more info. 

  • What air space is needed for the summo 64 , it doesn’t list it on the manuls down load , it only shows the 10,12 and 15 inch summos

    The basic airspace is 0.25 - 0.41 ft3 and the user guide has been added for more detailed information. 

  • What is suggested for breaking in your subs?

    We suggest playing low frequency music at very low volume for a few hours. Just enough to make the cone move up and down without a lot of volume output.
