Features & Specifications

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. 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.

How does this compare to the GLS8?
1 Answer
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 if you need additional help.

Can this subwoofer be using with a Sonos 250W amp?
1 Answer
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. 

Good choice

Is it possible to get a working demonstration of the outdoor subwoofers

1 Answer
Hi Aaron:

The FORZA10 is just a passive subwoofer so you need a dedicated subwoofer amplifier to go with it. What else can you tell me about your setup? Knowing more about your system will help me answer your question. The sub features free shipping and a 30-day performance guarantee.

Can you confirm if this is a powered subwoofer?
1 Answer
Hi Kris: The Forza-10 is a passive 10" Outdoor Subwoofer that needs a dedicated Subwoofer Power Amplifier. Currently, we have two OSD Audio Subwoofers that would work for this sub. Check out the SMP500 and the SAM300 (found on our web site under Black Series Amplifiers) There is no price online; you would have to call customer service and tell them Tim from Tech Support sent you. There are two new more affordable choices coming to our warehouse at the end of April 2019. The SMP200 and SMP300 both on the web site. One other thing to think about passive subs. When connecting up to 50 feet, we recommend using 14 Gauge wire. Over 50 feet you will need 12 Gauge. We offer both in Direct Burial rated cables (minimum 50 feet). TL/5502

Hi, I have 4 satellite/outdoor speakers running at 8 ohms on an Onkyo av receiver and Yamaha wxc50 preamp. Question - if I was to add this subwoofer, how do I connect it? This is a passive/non powered sub, right? So I would t use the sub out/lfe on the receiver. I see the sub has a single connector with a black and a red wire - how does this work? I need the power and signal from the receiver to run the sub, right? Thanks, Mike
1 Answer
Hi Mike: You would need a dedicated Subwoofer Power Amplifier to make this work with your system. The question is, are you using the Subwoofer for playing music from your Yamaha Pre-amp Musicast or your Onkyo AV Receiver for surround sound or even stereo mode from your AVR? If it is for music generated from the Yamaha WXC50, there is a dedicated Preamp signal level output. The ONKYO AVR also features a Preamp signal level output. In both cases, you will need a dedicated Powered Subwoofer Amplifier. Check out our SMP500 or our SAM300 (on our premium site under our Black Series). You would have to call for a unique quote from our Customer Service, mention Tim from Tech Support would suggest a special price. There are also two new amps coming in at the end of the month, the SMP200 and SMP300. That would give you a price range between $199.00 and $349.00. Good luck TL/5501
