What subwoofer box hits the hardest?

1.  
2. The thing is that the subwoofer box that strikes the most depends on different factors such as type of subwoofer, box construction and power that is supplied to the sub. However, it has to be noted that sealed subwoofer boxes are the two traditional types of boxes that are used for varied sound reproduction. Here’s a breakdown:
3.  

Ported (bass reflex) Subwoofer Boxes:

Hits Harder in Terms of SPL (Sound Pressure Level): In ported boxes, there is a vent known as a port whose dimensions are tuned to improve certain low-frequency outputs. These subwoofer boxes are usually louder in SPL (stand peak loudness) and richer in low frequencies. If you are in search of the subwoofer box that delivers rattling performances and deep, powerful impacts, a ported box is normally used.

Best for:
SPL competitions
High-output bass
Loud bass tones

Down4Sound Pro Subwoofer Box
Q-Logic Ported Subwoofer Box
The key innovation at Sundown Audio is the ported enclosures.

2. Sealed subwoofer boxes:

Hits harder in terms of accuracy and tight bass: Sealed boxes normally provide more accurate, smaller, and faster and slammier bass than ported boxes; choose the type that the subwoofer box manufacturer prefers. Although they do not generate as much SPL as a ported box, you will get clear and deep bass that is also accurate in its response. This is good for those who are interested in clear and non-distorted sound instead of very loud ones.

Best for:
All the music that needs accurate beats from bass (rock music, jazz music, etc.)
They come in various sizes (sealed boxes are usually smaller than the open ones).

Subwoofer box cabinets of JL are one of the many series of enclosed woofers that are sealed.
Rockford Fosgate Sealed Boxes
More advanced forms of Kicker Solo-Baric subwoofer boxes are built with sealed enclosures, not boxes.

3. Woofer boxes: hits hardest at specific frequencies:

Bandpass speakers are a combination of sealed and ported designs, but tailored to a specific frequency range. Their job is to produce large amounts of bass at certain frequencies, making them perfect for genres of music with that kind of base, such as hip-hop or electronic dance music. However, they tend not to be as sharp or wide as the first type of antenna, which means they are not as wide and clean.

Best for:
More specifically, it is capable of delivering very high specified power (SPL-based) in certain frequency bands.
Examples of Bass Frequency Enhanced (B.F.E.)-oriented genres (hip-hop, dubstep, etc.).

Key factors that affect how hard a subwoofer enclosure will hit are

The design of the enclosure

The type of bass enclosure—sealed, ported or even bandpass—and the tuning of the structure will determine how hard the subwoofer box hits. Basically, ported cabinets tend to produce more volume and impact than sealed ones but deliver more defined bass.

Subwoofer power handling

The amount of wattage your subwoofer is rated at is directly proportional to its ability to produce high-impact sound. Matching a high-wattage subwoofer to an ideal loudspeaker will optimise performance.

Tuning

With ported cabinets, the tuning ports, and therefore the frequency, play an enormous role in the way the subwoofer hits at certain frequencies. Tuning has been proven to improve performance when done correctly.

Subwoofer size

Large subwoofer boxes with larger drivers, such as 15 or 18 inches, produce more air movement and are more powerful, especially in vented enclosures, but smaller subwoofers with 10 or 12 inch drivers tend to be more defined and faster.

If you want the highest SPL (decibels) and the kind of bass response that gives the 'boom', goes the deepest and hits the hardest, then a ported cabinet is often the best choice. However, if you want tight, punchy bass, not necessarily earth-shattering bass, but good bass, then a sealed cabinet is preferable. For really specific bass frequencies, a bandpass may be the answer.

For the most powerful subwoofer box experience, consider pairing a powerful subwoofer box such as the Sundown Audio SA or X Series with a ported subwoofer box enclosure designed for the needs of your particular subwoofer box.
