MX15D4 vs KS10D4 Subwoofer Specs
Woofer Size
The DR Double ROCK MX15D4 features a 15-inch driver, while the KS10D4 uses a 10-inch cone. Larger diaphragms generally move more air, which helps produce lower frequencies with less excursion. The 15-inch unit is built for deep, resonant bass that you feel physically. The 10-inch model focuses on tighter, more accurate low-end response. You will notice a distinct difference in the sound character. The larger cone offers more physical presence, while the smaller one aims for precision. Your choice depends on whether you prioritize raw output or controlled accuracy.
Power Handling
Power ratings differ significantly between these two subwoofers. The MX15D4 handles 600 Watts RMS and 1200 Watts peak. In contrast, the KS10D4 is rated for 1000 Watts RMS and 2000 Watts peak. Higher RMS ratings indicate greater sustained power handling capability. The KS10D4 can manage more continuous energy without thermal stress. This makes it suitable for high-output amplifier setups. The MX15D4 is robust but rated for lower continuous power. You should match your amplifier’s output to these RMS values for optimal performance and longevity.
Resonant Frequency
The resonant frequency (Fs) indicates how low a subwoofer can naturally play. The MX15D4 has an Fs of 33.2Hz, allowing it to reproduce very deep bass notes. The KS10D4 has a higher Fs of 49.3Hz, which limits its lowest extension. Lower numbers mean deeper bass output. The 15-inch driver is better suited for sub-bass frequencies found in hip-hop and EDM. The 10-inch model focuses on mid-bass and punch. If you require audible sub-bass, the MX15D4 is the superior choice for low-frequency extension.
Sensitivity
Sensitivity measures how efficiently a subwoofer converts power into sound. The MX15D4 has a sensitivity of 88.1dB. The KS10D4 does not list a specific sensitivity value in its published specifications. Higher sensitivity means louder output for the same amount of power. Without a stated figure for the KS10D4, we cannot directly compare efficiency. You will need to rely on the power handling ratings to estimate performance. The MX15D4 provides a known efficiency metric for your calculations.
Enclosure Requirements
Both subwoofers work in sealed or ported boxes, but their volume needs differ. The MX15D4 requires 2.98 cubic feet for sealed enclosures and 3.76 cubic feet for ported ones. The KS10D4 is a standard 10-inch size, fitting most aftermarket boxes. The MX15D4 needs a larger, custom-built enclosure to reach its tuning frequency of 33Hz. The KS10D4 offers easier installation in pre-made boxes due to its smaller footprint. You must ensure your vehicle has enough space for the larger 15-inch unit.
Which DR Double Rock Subwoofer Fits You
Deep bass lovers with space for large enclosures
The 15-inch driver moves more air for deeper resonance. Its 33.2Hz resonant frequency targets lower notes than the 10-inch model. You get 600W RMS power handling and a 99 oz motor for control. This unit suits sealed or ported boxes up to 3.76 cubic feet for impactful low-end reproduction.
Listeners wanting high power in a compact footprint
This 10-inch sub handles 1000W RMS and 2000W peak power. It delivers tight response at 49.3Hz without muddying mids. The rigid aluminum basket and advanced cooling ensure durability during high-volume sessions. Its smaller 10-inch diameter fits standard aftermarket boxes while providing punchy, accurate bass for various music genres.
Installers prioritizing weight and physical dimensions
The 10-inch model weighs 27.5 pounds and measures 10 inches wide. While heavier than typical 10-inch subs, it remains more compact in overall volume than the 15-inch variant. The 15-inch unit weighs 18.5 pounds but requires significantly more space with a 15.3-inch diameter. Choose based on your available enclosure volume and mounting constraints.
