Don't Miss Out!

These woofers are the best performing woofer for saddlebags. We are big believers in this particular product. These speakers do not look like traditional high power speakers due to the unique design, but are the very best speaker for the job. A traditional woofer with a heavy iron magnet and a heavy moving mass (cone) just does not perform well in a saddlebag. These woofers are extremely efficient due to their low moving mass and neo magnets that are actually quite a bit more powerful than a traditional iron magnet. 

Want Bass?

The Cerwin Stroker SM8 has much more ruthlessly hard hitting bass than any other woofer including 10" subwoofers. And you can hear them at 80!

At American Hard Bag we have made a science out of getting big sound out of saddlebags. We are responsible for more thunderous, loud, hard hitting bikes than anyone. The key to getting loud bass that you can hear while you ride is to design the woofer system so that it plays at extreme volume levels down to 50 hz and then filter all bass below that frequency. 

Loud Highs

Not just a woofer. This is a full range speaker with an extremely wide dispersion. The mid and high frequency response of these woofers is purposely disproportionate. These speakers play louder as frequency rises. This makes it a perfect solution for saddlebags. Even pointing in at the wheel, these speakers sound crisp, loud, and crystal clear. This all adds a lot to the overall volume level and clarity of the entire sound system.
