For just $557.89, below its 30-day average of $574.59. The 90-day average sits at $565.40 and the 180-day average at $565.45, so this price is a genuine dip worth acting on if you have been shopping in this category.

What You're Getting

The Supernova MKIV-12 is a 12-inch dual firing powered subwoofer with a 450-watt Class A/B amplifier. SLAPS technology (Super Low Audio Power Saver) increases the dB output while drawing less power, which means louder, cleaner bass without taxing your electrical circuit. The variable crossover filter runs from 40 Hz to 180 Hz with a 12 dB/octave slope, giving you flexibility to blend with any speaker setup. High-level inputs and low-level outputs with automatic signal detection simplify installation whether you are using a receiver or a dedicated processor.

Who This Is For

Best for home theater builders who want deep, room-filling bass without stepping up to a 15-inch or dual-sub configuration. The dual-firing design and 450-watt amp make it a strong fit for medium to large rooms where a single front-firing subwoofer might leave dead zones.

Skip this if you are building a compact desktop near-field system or need a sealed enclosure for tight, musical bass in a small space.

Final Verdict

The Supernova MKIV-12 delivers legitimate subwoofer performance at a price that undercuts its own recent averages. For $557.89, you get SLAPS efficiency and dual-firing output that competes with subs costing $200 more.

If you are outfitting a dedicated theater room or upgrading from a budget sub. This is the price point to move on. Wait if your setup requires a smaller 10-inch driver or a sealed box design.
