When you compare a 300W vs 100W subwoofer, you are looking at two 10-inch powered speakers designed for home theater use. Both units feature MDF or braced cabinets to reduce resonance and include LFE inputs for easy connection to AV receivers. The main difference lies in their amplification and power handling. One offers 300W RMS Class A/B amplification, while the other provides 100W Class D amplification with a deeper frequency response down to 24Hz. This choice affects how you experience bass impact and efficiency.

Verdict: Choose the 300W model if you prioritize raw power and a classic Class A/B amplifier design. Select the 100W model if you require deeper low-frequency extension and precise tuning controls. Both are 10-inch powered subwoofers suitable for standard home theater setups.
Power, Amps, and Build Specs
Power Handling
The WMQ subwoofer lists a power handling rating of 300W RMS. This higher wattage suggests it can sustain louder output levels before reaching its limits. The Polk Monitor XT10 is rated at 100W. While both are powered units, the WMQ offers three times the stated power capacity. For listeners who want maximum headroom for loud movie explosions or high-volume music, the 300W rating provides a larger buffer. The 100W rating on the Polk is sufficient for most living rooms but offers less reserve power for extreme dynamic peaks. You should choose the higher wattage if you plan to push the system hard.
Amplifier Type
These two subwoofers use different amplifier technologies. The WMQ employs a Class A/B amplifier. This design is known for producing clean, detailed sound, though it typically generates more heat than other types. The Polk Monitor XT10 uses a Class D amplifier. Class D amps are generally more energy-efficient and run cooler. The Polk features a rigid, critically braced cabinet to manage heat and minimize resonance. The WMQ uses a heat sink in its MDF enclosure. Both designs aim to protect internal components, but the Class D efficiency of the Polk may result in less heat buildup during long listening sessions.
Connectivity
Both subwoofers offer standard connection options for home theater integration. The WMQ provides an RCA line input and a dedicated LFE (SUB) input. This allows you to connect directly to an AV receiver for bass management. The Polk Monitor XT10 also includes line level and LFE inputs. However, the Polk specifies that its LFE input is unfiltered, meaning the low-pass filter is disabled when using this connection. This gives you more control over crossover settings if your receiver handles bass management. The WMQ does not specify this detail. Both support straightforward setup with most modern receivers.
Enclosure Type
Build quality impacts sound clarity by reducing unwanted cabinet resonance. The WMQ uses a sturdy medium-density fiberboard (MDF) structure. This material is dense and helps dampen vibrations from the woofer. The Polk Monitor XT10 is housed in a rigid, critically braced cabinet. The bracing adds structural integrity to reduce sonic interference. Both designs prioritize a solid enclosure to ensure pure sound. The WMQ also mentions a heat sink integrated into the MDF. The Polk emphasizes down-firing bass to isolate the woofer sound. Both approaches aim to deliver tight, distortion-free bass without coloration from the cabinet itself.
Frequency Response
Low-frequency extension determines how deep the bass goes. The Polk Monitor XT10 specifies a frequency response that reaches as low as 24Hz. This allows it to reproduce very deep sub-bass frequencies often found in modern movies and special effects. The WMQ data does not list a specific frequency response range. It mentions delivering deep and tight bass through its 10-inch woofer and high-rigidity paper composite diaphragm. Without a stated lower limit, you cannot verify if it matches the Polk's 24Hz capability. If deep extension is critical, the Polk provides verified data for this spec.
Which Subwoofer Fits Your Room
Home theater enthusiasts with immersive formats
The Polk Monitor XT10 supports Dolby Atmos, DTS:X, and Auro 3D decoding. Its Class D amplifier delivers bass down to 24Hz. This unit offers precise control via variable crossover and phase polarity settings. It integrates seamlessly with timbre-matched Monitor XT speakers for a complete surround sound experience.
Listeners prioritizing raw output power
The WMQ subwoofer provides 300W RMS power handling with a Class A/B amplifier. This higher wattage rating suggests greater sustained output capacity. The 10-inch woofer uses a high-rigidity paper composite diaphragm for deep bass. Its sturdy MDF enclosure minimizes resonance, supporting clear audio for movies and games.
Users seeking simple connection options
The WMQ unit features both RCA line input and a dedicated LFE input. This straightforward connectivity allows quick setup with most AV receivers and TVs. The Class A/B amplifier design aims for clean sound reproduction. Its compact dimensions fit easily into living rooms or bedrooms without complex configuration.
