This model of the Power Acoustik MOFO is the best in terms of affordability. While we included it as a good inexpensive option in our list of the best competition subwoofers for a while, we don't think it's held well against other more obscure brands we've found recently. The article below is the original review as we wrote it back then. Our sentiment for this sub hasn't changed, we've just tested more units now.


  • Size: 15"
  • RMS: 1800Watts
  • Peak Power: 3000Watts
  • Sensitivity: 87 dB
  • Frequency response: 44-1,300Hz
  • Impedance: Dual 2 or 4 ohms
Power and Sensitivity

With an RMS of 1,700 Watts and peak power of 3,000 Watts, this sub can produce sound rivaling that of the more expensive options on this list.


A sensitivity level of 87 dB gives it a hefty push, in terms of sound output capabilities.

Voice Coils and Cone

Another outstanding feature on this MOFO model is the aluminum reinforcement fins and aluminum dust cap, which make for better sound quality.

This sub comes complete with a high-quality aluminum 2.5-inch, 4-layer, dual voice coils and a patent pending heatsink for top-notch heat dissipation.

This sub has some of the most sophisticated components, all for an outrageously low price.


This competition sub is available on either 2-ohm or 4-ohm impedances, so, as with many of the others on our list, you have options for how you want to wire it.

You can even go as low as 0.5 to 1 ohms to wire it, so you won’t have to buy an expensive amp to power it.


This last entry is the most realistic price-wise and definitely will not disappoint in its performance.

With its outstanding SPL and solid SQ, this MOFO model has all the power and clarity of a sub that would cost at least twice as much.

Some other features that make this competition sub the high-quality, high-powered monster it is are its nickel-plated compression wire terminals and its dual-stacked 340 oz. strontium ferrite magnets.

Considering all the top-notch components included in this sub, it comes at an insanely low price.
