    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 SMP200 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 SMP200.

    Doyle Robles • 12/17/2019, 2:17:43 PM Can this subwoofer be using with a Sonos 250W amp?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Doyle:Good question, the new SONOS Amplifier has a low (signal) level output connection (female RCA) for adding a dedicated Subwoofer. You have a choice of connecting directly to a Powered Subwoofer or a Dedicated Subwoofer Amplifier connected to our FORZA 10 which currently does not have an internal passive crossover network. We would recommend either our SMP300 or SMP500 DSP to power and control the FORZA10. Note: The FORZA10 is rated at 4-ohms if you wanted to add a second FORZA10 you would need to connect (wire) in Series. And we would recommend the SMP500 with DSP control and much more power to drive and make adjustments for two of the FORZA10s.You would set your levels for Phase, Adjustable Low Pass Filter, and Gain then control the volume level on your device connected to the SONOS Network.

    Rocky • 12/17/2019, 2:17:43 PM How does this compare to the GLS8?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Rocky:Both the GLS8 and the FORZA10 are passive Subwoofer that needs a dedicated powered Subwoofer Amplifier. But they are for two different applications. The GLS8 is meant to be buried in the ground with just a stove topped pipe with a mushroom cap that outputs a 360-degree low pass signal. The FORZA 10 works on a Flat surface like a patio or deck where the 10 inch woofer fires downward coupling with the surface below. The GLS will handle more power meaning it has an 8.0" woofer with a bigger magnet than the 10" sub found in the FORZA. Both Subwoofers feature drivers that optimize by their respective enclosures. The GLS8 is rated at 8 ohms so with most of our dedicated Subwoofer amplifiers you can drive two GLS8 in parallel so the amp will see a 4-ohm load. To add a second FORZA10 you would need to wire in Series so the amplifier would see an 8-ohm signal. The FORZA10 has slightly higher Sensitivity at 86dB vs. 84dB for the GLS8. So the FORZA takes less power to drive it but not a big difference. So it comes back to your application. In both cases, your best choice for a dedicated Subwoofer Power Amplifier would be our SMP500.Good luck, my email address is [email protected] if you need additional help.TL/5542
    Brian • 11/27/2020, 3:36:10 PM Does the Forza10 have both high and low level inputs? I have some good amplification in my system with available channels to use (Rotel / Parasound). Is there any reason I can't connect this to those amps as opposed to buying a dedicated Sub-woofer amp? Can I use a "speaker out" terminal to the amp and then to the sub, or does it have to be a sub-woofer out terminal. Thanks in advance for your help
    Customer Service • 12/04/2020, 3:35:06 PM
    Hi Brian: The FORZA 10 features a two conductor input connection (+/-). There is a low pass filter at around 300Hz so you can connect to a full range signal and get information up to 300Hz so there will be some mid/bass midrange signal coming out. You can try it and see if it is acceptable. Its rated to 300 watts so you should not hurt anything. Remember it is 4-ohm, so make sure you connect to a High Current amp that will do 4-ohm. Or you could use either our SMP300 or SAM300 at a minimum. Good luck TL/12/4/2020
    Brian L Shaw • 05/02/2021, 11:39:32 PM I have a Sony STR-DH590 5.2 reciever. Between this sub and the passive sub of the same design which would be a better choice for me?
    Customer Service • 05/10/2021, 12:01:17 PM
    Hi Brian: The subwoofer output of your SONY AVR is s signal level output that needs to connect to a powered Subwoofer or a dedicated subwoofer amplifier to drive either the FORZA10 (a passive sub) or the other Passive Subwoofer. Something like our SMP200 or SMP300 sub amps. Make sure you pick the Subs without the crossover or satellite connections. The sub should only have a single positive and negative two conductor speaker wire connection. TimL 5-10
    Adam Jannetta • 05/28/2021, 10:15:46 PM What is the approximate coverage area for bass produced by this sub?
    Customer Service • 06/07/2021, 1:47:14 AM
    Hi Adam: The FORZA 10 outdoor subwoofer would cover an area of 1500 to 2500. The FORZA 10 is Rated at 4-ohms. We recommend either our SMP200 (1500 sq. ft.) or SMP300 (2500 sq. ft.). We also have a 12 inch sub the XSub12. You also need to consider which satellite speakers you are using and what is their is their Frequency response. It appears there is a 30% increase in coverage as you go from 8" to 10" to 12". TimL/6-6-21
