OSD Forza 10 10" Outdoor Subwoofer with 300W of Power and High-Impact Molded Enclosure, IP66-rated Weather-Resistant

I purchased this back in April 2022 as part of a patio upgrade, and originally paired it with a Fosi M03 200W subwoofer amp. The other components were simple - Fosi DA2120C 240W bluetooth amp which paired with a set of Definitive Technology AW6500 outdoor speakers. At first, the bass was muddy and the sub would sound as if it was clipping and too much amp for it. I upgraded the amplifier to a Crown XLS1002 running in bridged mode @700W. WOW it was like a whole different sub! This product puts out some good quality bass, but you should keep in mind you can adjust the amp settings to a higher cutoff frequency, say 235hz and you'll get more thump (if that's what you desire). I decided to try a higher "quality" subwoofer, so I purchased JBL Professional Control SB2210. To my amazement, and after listening to many different genres of music and made all other settings equal, I could not distinguish any difference except for 2 things. The JBL is more pricey and the build felt like the housing was cheap plastic. So, bottom line if one expects good quality sound from this sub, go with a higher powered, higher quality amplifier and it will make all the difference! Side note I also decided to upgrade my main speaker bluetooth amp and purchased an S.M.S.L. SA400. Pricey but much better quality, clean undistorted sound . Since then, any gatherings I've had, my guests are amazed at the sound and the consistent remark is the bass is very clean and doesn't overwhelm.Adding a note:Since it's a downward firing sub, it doesnt sound as good if you place it on a softer surface such as grass, dirt, gravel. I moved it to a concrete surface and there was a huge difference. I placed some concrete pavers on the gravel where I originally placed it. Then did some research to understand more about bass and how their soundwaves work, then understood why a grass surface didnt work as well. Also if you place a plant or vase on top, it will slide off with the vibration. I placed 3 plastic bumpers with double sided tape to keep it in place. I also purchased some silicone sound insulators (feet you can stick to the bottom to minimize vibration). Hope this helps!

This sub hits! I have this paired with some Crestron landscape speakers. This sub changed the entire outdoor space adding so much warmth and low end to the music. It’s an easy install. I secured it to a large paver using some TapCon screws secured to the paver. The sub has keyhole openings on the bottom so it sits on top of the crews then a twist of the sub to lock it on. Zero movement and tons of SPL! I was pleasantly surprised. I paired it with a small Bass controller as a preamp to really maximize the sound. Check out the pictures!

Having gone through a few other options for outdoor subwoofers, I was skeptical about trying another one out, especially without seeing any Amazon reviews. But I did take a chance and I will admit that I'm more than impressed. I have it tucked away in the middle of my new double pergola patio and have it paired up with a bridged Behringer A800 Power Amplifier. This speaker does take a fair amount of power to really give it some volume and headroom.I'll also say that it is well put together, hefty, and a bit bigger than I had imagined. (Don't you love reviews like this - as if the dimensions aren't provided in the description! LOL!!)A few other items to note - sitting it on the ground or hard surface is recommended in order to get the best response from this subwoofer. That does cause it to vibrate and buzz a little from the plastic legs - so I added some 1 1/4" isolation feet (1.25" Platinum Silicone Hemisphere Bumper, Non-Skid Isolation Feet with Adhesive) to the bottom of each of the four "corners" - and it solved that problem right away.I have a set of Definitive Technology AW6500 speakers and a set of Polk Audio Atrium 6 outdoor speakers that get played through my Sonos Amp (with this subwoofer getting a 70-80 hz direct subwoofer out crossover to the dedicated amp) and it more than rocks my backyard with clear sound.In all - it is a great low-end additional to my outdoor space and I couldn't be happier. My friends know me - "you can never have too many subwoofers" and for the price and performance of this one, I'm thrilled to now take that mantra outdoors.

This subwoofer I'm in a love hate relationship with. I got it for my large outdoor patio to bring some thump to the party. It sounds so good you can't tell where the speakers left off and the subwoofer picks up. This makes for a very full and satisfying sound, it's a beautiful thing. I think it's got plenty of power for 90% of people, I am just a bit extra. I like to feel my music. I'm feeding it with a Fosi 320W receiver which powers my speakers but sends input to a 300W Nobsound pre-amplifier which directly powers the subwoofer. My only complaint is the sub still leaves me craving a good thump. It sounds great, I love the fullness of sound my backyard now has but not 100% fulfilled with the amount of low tones produced overall. I'm going to add a 600W RMS 12" car subwoofer/amp kit to finish the job. It will be in addition to this unit.

It sounded OK when I first got it worked for 30 minutes and then stopped then I had to dig it all up again. Couldn’t hear anything wrong. Just stopped working.
