🚨 IMPORTANT UPDATE — AMERICAN HARD BAG / HERTZ SUBWOOFER ORDERS 🚨

We owe everyone waiting on our new American Hard Bag modular subwoofer enclosures with Hertz subwoofers an update — and first and foremost, an apology.

This shipment has taken considerably longer than anyone anticipated. We’ve had estimated arrival dates change multiple times, and we know how frustrating that is when you’ve already spent your money and are waiting on your system.

We want to be completely transparent about what’s happened, where the product is today, and what Volunteer Audio is doing about it.

IT STARTED WITH TYPHOON DOLPHIN

Our container was originally scheduled to be loaded aboard its ship around August 21st.

Earlier in August, Typhoon Dolphin disrupted operations around the major Shanghai and Ningbo-Zhoushan shipping ports. Ships were delayed, port operations were interrupted, and a significant backlog developed that continued affecting vessel schedules after the storm itself had passed. By the time we reached our original August 21st loading window, the shipping system was still working through those delays.

Our container ultimately wasn’t loaded in Shanghai until August 25th — approximately four days later than originally planned.

Unfortunately, that was only the beginning.

THEN CAME TYPHOON SAUDEL

Just as our container was finally getting loaded and underway, Typhoon Saudel created another round of severe-weather disruptions in the region.

According to the shipping information we’ve received on our particular shipment, after getting out of port and into the South China Sea, the vessel encountered additional severe-weather restrictions and was held up for approximately 10 more days before being allowed to continue its voyage.

So this wasn’t one simple delay.

Typhoon Dolphin disrupts the ports → the backlog pushes our original August 21st loading back → our container finally loads August 25th → Typhoon Saudel and additional severe weather create another disruption → our ship loses approximately another 10 days.

And unfortunately, the problem doesn’t end when the weather clears.

When large numbers of ships are delayed, all of those vessels still have to get back into the shipping schedule. Then they begin reaching destination ports later and closer together, where they still have to be assigned berths, unloaded, processed and transferred.

It creates a domino effect across the entire supply chain.

That’s why the estimated arrival date we’ve been receiving has changed multiple times and continued getting pushed farther back.

A shipment we originally expected to have around the first week of September is now showing an estimated arrival at the Port of Long Beach around September 24th.

It’s honestly incredible that a shipment that should have been here during the first week of September can end up arriving at the West Coast near the end of the month.

We are frustrated too, and we’re truly sorry that our customers have had to wait through it.

IF YOU ARE WAITING ON HERTZ SUBS, THIS IS VERY IMPORTANT:

Volunteer Audio purchased every production Hertz subwoofer that was available for these systems.

There isn’t another batch of Hertz subs sitting at the factory that we can simply put on an airplane.

We bought the available production inventory. It’s ours. And it’s on this container.

We’ve asked about air freight. We’ve looked at expediting. We’re currently working on the possibility of diverting product directly to our supplier’s location in Southern California once the container reaches Long Beach and then air-freighting or second-day airing product to Volunteer Audio in Tennessee.

We’re willing to spend a substantial amount of additional money to shorten this delay wherever we possibly can.

But when it comes specifically to the Hertz subwoofers, there simply aren’t any more available to air freight.

We cannot air-freight something that doesn’t exist.

The production Hertz subs we’re waiting for are already on the water, and unfortunately, there isn’t anything Volunteer Audio, Hertz or American Hard Bag can do to make that ship move faster.

That’s how limited the Hertz inventory situation is right now:

Even Volunteer Audio doesn’t have production Hertz subs in our own demo bike.

The Hertz subs currently playing in our demo bike are the original PROTOTYPES.

We have 100+ customers currently waiting on Hertz systems, and when the production Hertz subs arrive, those customers are our priority.

WHAT DOES THIS MEAN FOR SMOKY MOUNTAIN BIKE WEEK?

This delay has significantly affected our plans as well.

Volunteer Audio will be working Smoky Mountain Bike Week, and our crew has to begin setting up on September 24th.

The rally begins September 26th and runs through October 4th.

We have been extremely excited about bringing these new American Hard Bag modular subwoofer systems to the rally. Our original plan was to have inventory there so people could hear them on our demo bikes, purchase them, and even have systems installed during the event.

Unfortunately, our container is now showing an estimated arrival at the Port of Long Beach on the same day we’re supposed to begin setting up for the rally — September 24th.

So we’re making some changes.

We are currently looking at air-freighting Velocity subwoofers into the country because additional Velocity inventory can be produced and shipped by air.

Our goal is to have the Velocity version of these modular subwoofer systems available at Smoky Mountain Bike Week so people can hear them and, hopefully, purchase and have them installed during the rally.

But we want to be very clear about the Hertz version:

We do NOT plan to have production Hertz subs available for sale or installation at the rally.

If that container arrives as currently projected and we begin receiving Hertz inventory during the week of the rally, those subs are not going into show inventory.

They’re going into boxes.

Every Hertz subwoofer we receive will immediately begin shipping to the 100+ customers who have already ordered and have patiently waited through these delays.

We believe that’s the right thing to do.

We’re not going to take Hertz subs to an event and sell them to someone who walks up to our booth while customers who trusted us with their money weeks ago are still waiting on theirs.

Existing Hertz customers come first. Period.

PLEASE STILL COME SEE US AT SMOKY MOUNTAIN BIKE WEEK!

We should still have our Hertz demo bike at the rally — but remember, even that bike is running the original prototype Hertz subwoofers because we don’t have production inventory sitting here.

Come hear it.

And hopefully we’ll also have the new Velocity subwoofer systems there for demonstration, purchase and installation.

We’ve been incredibly excited about these systems, and while we’re disappointed that these shipping delays have changed our plans, we genuinely believe these subs are going to be worth the wait.

Most importantly, to every customer who has already trusted Volunteer Audio with your money:

THANK YOU.

Thank you for your patience. Thank you for your understanding. And thank you for continuing to trust us while we’ve worked through something that has largely been outside of our control.

We’re spending additional money, making the phone calls, looking at expedited freight, air freight, second-day shipping and every reasonable option available to shorten this delay.

We will continue giving you the best information we have at the time we have it.

If the September 24th estimate changes, we’ll tell you.

If we find a way to get them here faster, we’ll tell you.

We’re not going to hide from a delay just because it’s outside our control. We’re going to keep you informed until every one of these orders is fulfilled.

Thank you again for your patience and for trusting Volunteer Audio.

American Hard Bag Modular Bass System

Available with Your Choice of Hertz® or Velocity® 10-Inch Subwoofers

More than a subwoofer. A complete bass system engineered specifically for the 2023.5+ Harley-Davidson Touring platform.

Experience the bass your Harley has been missing without permanently giving up the saddlebag storage you depend on.

The American Hard Bag Modular Bass System is engineered specifically for 2023.5 and newer Harley-Davidson Touring motorcycles, combining precision roto-molded enclosures with your choice of premium 10-inch subwoofers and integrated 8-inch passive radiators.

Unlike traditional saddlebag subwoofer systems that rely on the entire saddlebag as the acoustic enclosure, each American Hard Bag enclosure is completely self-contained. This innovative design delivers deeper, cleaner bass while allowing your saddlebag lid speakers to perform without being affected by unwanted air pressure inside the saddlebag.

The result is a system that sounds better, installs cleaner, preserves your motorcycle’s handling characteristics, and gives you the flexibility to reclaim your storage space whenever your ride requires it.

A Modular Bass System Designed Around the Way You Ride

One of the biggest compromises with most Harley-Davidson saddlebag subwoofer systems is the permanent loss of valuable storage space.

The American Hard Bag Modular Bass System eliminates that compromise.

Each enclosure securely mounts inside your factory saddlebag using the original mounting locations while remaining completely removable. Whether you’re commuting, heading out for a weekend ride, or packing for a cross-country adventure, your motorcycle can be configured in just minutes.

Three Ways to Ride:
Maximum Bass

Install both enclosures and experience the full performance of a true dual-subwoofer system.

Maximum Flexibility

Need room in one saddlebag?

Simply remove one enclosure while leaving the other installed. You’ll retain impressive bass performance while regaining the full storage capacity of the opposite saddlebag.

Maximum Storage

Planning a long trip?

Remove both enclosures and restore the full storage capacity of both factory saddlebags.

When you’re ready for incredible sound again, simply reinstall the enclosures and reconnect the included plug-and-play wiring harness.

Bass when you want it. Storage when you need it.

Note: This system installs inside your existing factory Harley-Davidson saddlebags. Saddlebags are required and are not included.

A Better Way to Build Bass

Traditional Harley-Davidson saddlebag subwoofer systems often rely on the entire saddlebag as the acoustic enclosure.

That means every bass note creates pressure throughout the saddlebag, forcing your lid speakers to work against constantly changing air pressure. Many systems require additional baffles or isolation panels behind the lid speakers simply to maintain proper performance.

The American Hard Bag system was engineered differently.

Each enclosure houses a dedicated 10-inch subwoofer paired with an 8-inch passive radiator inside its own precision-engineered roto-molded enclosure.

Because the enclosure is completely self-contained, low-frequency energy remains inside the enclosure not inside your saddlebag.

  • The benefits are substantial.
  • Saddlebag lid speakers perform naturally without unwanted pressure loading.
  • No additional baffles or isolation panels are required behind your lid speakers.
  • The passive radiator delivers deeper bass and greater efficiency than traditional compact sealed designs.
  • Midbass and sub-bass work together instead of competing against one another.
  • Every speaker on the motorcycle performs as part of one balanced audio system.
  • The result is deeper bass, greater clarity, and a more natural listening experience.

Engineered for Performance Without Compromising Your Ride

Adding bass to a Harley-Davidson shouldn’t come at the expense of the motorcycle’s handling, balance, or touring capability.

From the very beginning, the American Hard Bag Modular Bass System was engineered with weight, efficiency, and real-world usability as primary design goals.

Each fully assembled enclosure weighs approximately 17 pounds, keeping the system within Harley-Davidson’s recommended saddlebag load capacity. The result is exceptional bass performance while preserving the balanced handling characteristics riders expect from their motorcycle.

Rather than relying on oversized amplifiers and excessive power to create bass, this system has been engineered for efficiency. The combination of the precision enclosure, optimized passive radiator, and carefully matched subwoofer produces impressive output while making exceptional use of every watt available from your amplifier.

Designed to Deliver:
  • Approximately 17.8 pounds per enclosure
  • Designed within Harley-Davidson’s recommended saddlebag load limits
  • Preserves the motorcycle’s natural handling characteristics
  • Outstanding bass output without requiring excessive amplifier power
  • Efficient acoustic design that maximizes every watt

Because the best motorcycle audio upgrade shouldn’t make your motorcycle feel like a compromise.

Designed for Volunteer Audio Stage Systems

This package has been engineered specifically as an expansion for Volunteer Audio’s Hertz Stage 2 and Stage 4 audio systems.

The amplifier configuration is simple and effective.

Front amplifier channels power up to four full-range speakers.

Rear amplifier channels power the dual subwoofers.

No additional amplifier is required when installed with the recommended Volunteer Audio Stage systems.

The result is a properly balanced system with crystal-clear highs, dynamic midrange, and deep, authoritative bass.

The American Hard Bag Modular Bass System is available with your choice of two premium 10-inch subwoofers.

Both have been extensively tested in this enclosure and both deliver exceptional performance. Neither is better. They simply have different personalities.

Velocity Performance Edition

Engineered Specifically for the American Hard Bag Enclosure

The Velocity 10-inch subwoofer wasn’t selected from an existing catalog.

It was engineered specifically for the American Hard Bag enclosure, creating a system where the driver, enclosure, and passive radiator were developed together as a complete acoustic package.

Rated at 300 Watts RMS and 600 Watts Maximum Power, the Velocity subwoofer features an injection-molded cone, Santoprene surround, oversized 56-ounce ferrite motor, and a 38 mm TIL voice coil to deliver exceptional punch, musicality, and long-term reliability.

If your playlist is filled with country, rock, blues, classic rock, or live recordings, the Velocity Performance Edition delivers outstanding impact and natural musical accuracy.

Ideal For: Country, Rock, Classic Rock, Southern Rock, Blues, and Live Recordings

  • 300 Watts RMS
  • 600 Watts Maximum Power

Hertz Reference Edition

Legendary Hertz Performance

The Hertz CS 250 S2 has earned a reputation for delivering exceptionally deep, controlled bass from compact enclosures, making it an ideal match for the American Hard Bag Modular Bass System.

Rated at 300 Watts RMS and 600 Watts Maximum Power, the CS 250 S2 utilizes a high-density ferrite motor, polypropylene cone, and precision-engineered suspension to reproduce the lowest octaves with outstanding authority and control.

If your music library includes hip-hop, rap, EDM, pop, or other bass-heavy genres, the Hertz Edition delivers the effortless low-frequency extension that brings those tracks to life.

Ideal For: Hip-Hop, Rap, EDM, Pop, R&B, and Bass-heavy playlists

Volunteer Audio Recommendation

At Volunteer Audio, we’ve spent countless hours listening to, tuning, and testing both versions of this system.

Rather than offering a one-size-fits-all solution, we chose to offer two distinct subwoofer options because each excels with different styles of music.

If your playlist is primarily country, rock, blues, or live recordings, we generally recommend the Velocity Performance Edition. It delivers exceptional punch, outstanding musicality, and was engineered specifically for the American Hard Bag enclosure.

If your music leans toward hip-hop, rap, EDM, or you simply want to reproduce the deepest notes possible, we recommend the Hertz Reference Edition for its exceptional low-frequency extension.

There isn’t a better version.

There’s simply the version that’s better suited to the music you enjoy most.

If you’re unsure which system is right for you, give our team a call. We’ll be happy to help you choose the perfect setup for your motorcycle and your listening preferences.

Why We Sell This System

At Volunteer Audio, we evaluate every product using one simple question:

Would we install it on our own motorcycles?

It delivers exceptional low-frequency performance without permanently sacrificing your saddlebag storage. It preserves the motorcycle’s handling characteristics through an efficient, lightweight design. It integrates seamlessly with our Stage audio systems. And thanks to its modular design, it adapts to the way riders actually use their motorcycles.

  • Some days it’s your daily transportation.
  • Sometimes it’s loaded for a thousand-mile road trip.
  • Other times you’re riding with empty saddlebags and your favorite playlist turned all the way up.
The American Hard Bag Modular Bass System was engineered for every one of those rides:
  • Install both enclosures when you want maximum bass.
  • Remove one when you need additional cargo space.
  • Remove both when your touring plans require every inch of storage.
  • No permanent sacrifice.
  • No unnecessary weight.
  • No compromise in the way your motorcycle rides.
