B2 Audio Subwoofers
Sold by AudioSellerz.com
Shop B2 Audio Subwoofers at AudioSellerz.com for everything from compact daily-driver bass systems to serious high-output car audio builds. The B2 Audio subwoofer lineup covers multiple sizes, power levels, voice-coil configurations, and system goals, giving customers options whether they want a simple single-sub setup or a much more aggressive bass system.
Audio Sellerz currently carries B2 Audio subwoofer options across several series, including RAVE, RIOT, RAGE, RAGEXL, RAMPAGE, and other B2 designs. The lineup includes compact 6.5-inch and 8-inch subwoofers, popular 10-inch and 12-inch options, and larger 15-inch and 18-inch woofers for builds where enclosure space, amplifier power, and electrical support allow for substantially more output.
Browse the available B2 Audio subs below or return to the main B2 Audio collection to shop B2 amplifiers, speakers, DSP processors, and other B2 Audio equipment.
Choosing the Right B2 Audio Subwoofer
The best B2 Audio subwoofer is not automatically the biggest woofer or the model with the highest advertised wattage. The right choice depends on how the complete system is being built.
Before choosing a B2 subwoofer, consider:
- Available enclosure space
- Subwoofer diameter
- RMS power handling
- Voice-coil configuration
- Final wired impedance
- Amplifier power
- Electrical-system capability
- Desired low-frequency response
- Daily-driver vs higher-output use
- Single-subwoofer vs multiple-subwoofer system
A properly designed system should be planned around the subwoofer, amplifier, enclosure, wiring, electrical system, and tuning working together. Simply installing a powerful woofer without matching the rest of the build can lead to poor performance or damaged equipment.
B2 Audio Subwoofer Sizes
B2 Audio offers subwoofers across a wide range of sizes. Each size can work extremely well when it is used in the right application.
B2 Audio 6.5-Inch Subwoofers
A 6.5-inch subwoofer can be useful when enclosure space is limited but you still want substantially more low-frequency output than normal door speakers can provide. B2 offers high-output compact designs for customers who want to fit serious bass into smaller spaces.
Compact subwoofers can also work well in multi-sub builds where several smaller drivers are used to create additional cone area.
Compare additional options in our 6.5-inch subwoofer collection.
B2 Audio 8-Inch Subwoofers
B2 Audio 8-inch subwoofers are a strong option for customers who want compact enclosure requirements without giving up serious bass capability. The live B2 lineup includes high-excursion 8-inch designs for both daily and higher-output applications.
An 8-inch sub can make sense in trucks, hatchbacks, compact vehicles, behind-seat installations, custom center consoles, or multi-subwoofer builds where space is limited.
Shop more 8-inch car audio subwoofers.
B2 Audio 10-Inch Subwoofers
A 10-inch subwoofer can provide an excellent balance between enclosure size, output, and low-frequency extension. B2 offers 10-inch designs across different power levels, including higher-excursion models intended for considerably more aggressive bass systems.
Ten-inch subs are popular in single-sub and dual-sub systems where customers want strong output without the enclosure requirements of larger 15-inch or 18-inch woofers.
Compare the full selection of 10-inch car audio subwoofers.
B2 Audio 12-Inch Subwoofers
The 12-inch subwoofer is one of the most popular sizes in car audio because it works well in a huge range of vehicles and system designs.
The B2 Audio lineup includes multiple 12-inch options ranging from shallower, lower-power daily-driver designs to substantially higher-power RAGE and RAMPAGE models.
A 12-inch B2 subwoofer can make sense for:
- Single-subwoofer trunk builds
- Dual-12 systems
- Daily-driver bass systems
- Loud daily builds
- Higher-power ported enclosures
- Systems where output and enclosure size both matter
Browse all 12-inch car audio subwoofers available from Audio Sellerz.
B2 Audio 15-Inch Subwoofers
A 15-inch subwoofer provides more cone area than a comparable 12-inch driver and can deliver a larger low-frequency presence when the enclosure and amplifier power are designed around it.
B2 offers 15-inch options for customers building serious daily systems and much larger high-output setups. These larger subs need enough enclosure space and electrical support to perform correctly.
Shop additional 15-inch car audio subwoofers.
B2 Audio 18-Inch Subwoofers
An 18-inch subwoofer is typically chosen when maximizing cone area and low-frequency output is a major part of the system goal. B2 Audio offers high-power 18-inch models intended for builds with the enclosure volume, amplifier power, wiring, and electrical system required to support them.
An 18-inch woofer is not automatically better than a smaller subwoofer. It only makes sense when the vehicle and complete system can support the larger driver.
Compare more 18-inch car audio subwoofers.
B2 RAVE Subwoofers
The B2 Audio RAVE lineup includes options aimed at customers who want B2 equipment without automatically jumping into the most extreme system level.
RAVE models can make sense for daily-driver bass systems where space, power, cost, and practical installation requirements matter.
For example, B2 offers shallow-mount 12-inch options within the RAVE lineup for builds where mounting depth is limited.
B2 RIOT Subwoofers
B2 Audio RIOT subwoofers step into stronger daily-driver and high-output territory with models available in common car audio sizes and multiple voice-coil configurations.
RIOT subs can be a good fit for customers who want real bass output without immediately moving into B2's most aggressive competition-oriented designs.
B2 RAGE Subwoofers
The B2 Audio RAGE lineup gives customers additional power and performance options for builds that demand more from the subwoofer system.
When considering a higher-power B2 subwoofer, make sure the amplifier, enclosure, wiring, charging system, and battery capacity are all being planned at the same time.
B2 RAGEXL Subwoofers
RAGEXL models move further into higher-output applications. These types of subs are better suited to systems where the customer is intentionally building around higher power and has enough enclosure and electrical capacity to support it.
Moving into a larger-power subwoofer usually requires more than simply buying a larger amplifier. Power cable size, ground paths, fuse protection, alternator output, battery capacity, and voltage stability become increasingly important.
B2 RAMPAGE Subwoofers
B2 Audio RAMPAGE subwoofers are among the more aggressive woofers currently represented in the AudioSellerz B2 lineup. The collection includes RAMPAGE models across several sizes, including compact 6.5-inch and 8-inch designs as well as larger 10-inch, 12-inch, 15-inch, and 18-inch high-excursion woofers.
These are the types of subs that should be chosen as part of a complete high-output system plan rather than treated as a simple factory-audio upgrade.
B2 Audio Competition Subwoofers
B2 also offers competition-oriented subwoofer designs for customers building systems where extreme output and power handling are priorities.
A competition-style subwoofer can require significantly more amplifier power, enclosure strength, port area, electrical capacity, and installation planning than a normal daily-driver woofer.
If you are moving into this level of system, do not overlook the supporting equipment. The woofer may be the part everyone sees, but the electrical and enclosure are what allow it to actually perform.
Matching a B2 Audio Subwoofer With an Amplifier
Start with the subwoofer's RMS power handling and voice-coil configuration.
The number of voice coils and their impedance determine the loads that can be presented to the amplifier. A dual 1-ohm subwoofer, dual 2-ohm subwoofer, and dual 4-ohm subwoofer do not wire to the same final loads.
Before buying the amplifier:
- Determine how many subwoofers will be used.
- Identify the impedance of each voice coil.
- Determine the available final wiring configurations.
- Choose the target amplifier impedance.
- Compare the amplifier's RMS output at that impedance with the subwoofer system's RMS capability.
If you want to keep the system within the B2 lineup, browse our B2 Audio Amplifiers. You can also compare all available monoblock car audio amplifiers.
Choosing the Right Subwoofer Box
The enclosure is one of the most important parts of the bass system. A strong subwoofer in the wrong box can perform poorly even when the amplifier and wiring are correct.
Before choosing or building an enclosure, verify:
- Recommended net enclosure volume
- Subwoofer displacement
- Port displacement
- Port area
- Port length
- Tuning frequency
- Mounting depth
- Baffle strength
- Available vehicle space
Browse our complete car audio subwoofer box and enclosure collection when you need an enclosure for your build.
Sealed vs Ported Subwoofer Boxes
A sealed enclosure is generally compact and can provide controlled bass response when the subwoofer is designed for that application.
A properly designed ported enclosure can provide increased efficiency and output around its tuning range, but port size, tuning, and net airspace all need to be correct.
Neither design is automatically better. The correct enclosure depends on the subwoofer, vehicle, available space, music preferences, and system goal.
Electrical Upgrades for High-Power B2 Audio Subs
As subwoofer power increases, current demand increases as well. A high-power B2 subwoofer system can easily exceed what a factory electrical system was designed to support.
Depending on system power, electrical upgrades can include:
- Larger power and ground wiring
- Big 3 charging-system wiring upgrades
- Additional battery capacity
- Lithium or other upgraded energy storage
- A high-output alternator
Browse our high-output alternators, car audio lithium batteries, and Big 3 upgrade kits when planning the electrical side of a larger system.
Power Wire & Fuse Protection
High-power amplifiers require properly sized power and ground wiring. The correct cable size depends on current demand, cable length, conductor material, amplifier efficiency, and the rest of the electrical system.
Shop car audio power and speaker wire, amplifier wiring kits, and fuse blocks and power distribution to complete the installation correctly.
Setting Up a B2 Audio Subwoofer System Correctly
Once the equipment is installed, proper tuning matters just as much as proper hardware selection.
Check:
- Final subwoofer impedance
- Amplifier gain structure
- Low-pass crossover settings
- Subsonic filter settings when applicable
- Source-unit output
- DSP settings when used
- Electrical voltage under load
- Clipping
Amplifier gain is not a volume control. Excessive gain and clipping can damage a subwoofer even when the amplifier's advertised wattage appears to be appropriate.
B2 Audio Subwoofer Frequently Asked Questions
Does Audio Sellerz sell B2 Audio subwoofers?
Yes. AudioSellerz.com carries B2 Audio subwoofers across multiple sizes and series, including daily-driver and higher-output options.
What size B2 Audio subwoofer should I buy?
Choose based on available enclosure space, desired output, amplifier power, and how the vehicle will be used. Smaller subs can work extremely well in space-limited systems, while larger 15-inch and 18-inch woofers require more enclosure volume but provide additional cone area.
Are B2 Audio subwoofers good for daily systems?
B2 offers several subwoofer series and power levels, so the lineup includes options that can work in daily-driver systems as well as considerably more aggressive builds.
Does a B2 Audio subwoofer need a special amplifier?
No specific brand of amplifier is required. The important factors are RMS power, final impedance, amplifier stability, wiring, and electrical capability. A properly matched B2 amplifier can be used, but amplifiers from other manufacturers can also work when correctly matched.
Can I run two B2 Audio subwoofers?
Yes, provided the enclosure, amplifier, wiring, final impedance, and electrical system are designed for the pair. Always calculate the final load before choosing the amplifier.
Do I need a high-output alternator?
Not every B2 system requires one. Electrical requirements depend on amplifier current demand and the capability of the vehicle's factory charging system. Higher-power builds are more likely to need alternator and battery upgrades.
What box should I use with a B2 Audio subwoofer?
Use an enclosure designed around the specific subwoofer's recommended airspace and application. Ported boxes also need appropriate port area and tuning. Do not assume any box that fits the speaker diameter is automatically correct.
Can Audio Sellerz help me choose a B2 subwoofer?
Yes. Use the live chat bubble on AudioSellerz.com and tell us your vehicle, available enclosure space, amplifier or planned power level, how many subs you want to run, and what type of bass you are trying to achieve.
