Designed to blend within any outdoor setting, the FORZA-10 is a powerful and stealthy outdoor rated subwoofer that enhances outdoor sound systems by adding crucial bass notes for a more enriching surround sound experience. FORZA-10 cranks out 300W of power and includes a 10” polypropylene cone woofer and a high impact molded plastic enclosure with a unique antique bronze finish. Truly weather-resistant, the FORZA-10 is IP66 rated which means it is 100% sealed and protected from dirt and dust as well as powerful water jets such as sprinklers. Its unique curved shape and down-firing port makes it the perfect addition to decks and porches, but you can place it anywhere you run speaker wire. For optimal performance, however, we recommend placing this subwoofer on a paved or hard surface. The FORZA-10 also includes a built-in eye bolt that allows you to anchor it to the location to prevent theft or to keep it firmly in place. Pair this outdoor subwoofer with a mono subwoofer amplifier like the OSD SMP300 and combine it with any of our landscape satellite speakers, and you’ll have an outdoor audio system that rivals your indoor system.
Why Add an Outdoor Subwoofer?
Most outdoor speakers are not designed to cover lower frequencies so adding a subwoofer to a backyard audio system can make a huge difference in the quality of sound you experience. If you have outdoor speakers in your patio or backyard, you’re hearing mid and high frequencies and some bass so adding an outdoor subwoofer not only delivers missing bass notes, but also takes the low-frequency burden off the other speakers which will optimize your entire system.
Do I Need a Subwoofer Amplifier?
Yes! The Forza-10 is a passive subwoofer and needs a subwoofer amplifier to power it. An ideal match is our SMP-300 which is rated at 500W peak power and 250W continuous RMS.

What's on your mind?

Charles • 09/20/2021, 4:16:57 PM This sub has 4 keyhole slots used to anchor the unit. I thinking about getting rubber feet with threads to insert into the slots. Does anyone know the diameter of the keyhole slots for this unit so I know the thread size of the screws to get?
