This backyard subwoofer may shake a few plants and perhaps some neighbors too but it promises to deliver the kind of bass you've been looking for to fill the backyard, patio or pool area with detailed, crisp and heart-pounding low notes. Although it may appear to look like a simple and attractive rock found in any backyard or garden, inside the RSUB300 hides a robust 10' reflective woofer and an 8-inch subwoofer for incredibly realistic bass notes to round out a 2.1 or 5.1 or higher outdoor surround sound system. Designed specifically to provide the best sound in open air environments, the RSUB300 includes a rigid and acoustically inert enclosure with aerospace-grade multi-layer composite cabinetry that protects the outdoor subwoofer from the elements such as rain, snow and high temperatures.

What Are the Benefits of Adding an Outdoor Subwoofer? 
Adding a subwoofer to a backyard sound system makes a lot of sense and here's why. If you have outdoor speakers in your patio or backyard, you're hearing mid and high frequencies and some bass. But outdoor speakers are not designed to handle only low frequencies; that's a subwoofer's job. What many people don't realize, however, is that when you add an outdoor subwoofer, it takes the low-frequency burden off the other speakers. By adding a subwoofer, you'll not only hear awesome bass, it will optimize your surround systems because those speakers can focus on the sound frequencies for they were designed. 

Protecting Your Outdoor Subwoofer
The OSDRSUB300 is built to last with a rigid and acoustically inert enclosure with aerospace grade material that protects the 10" reflective woofer and 8" woofer; however, we recommend you place the outdoor subwoofer in a shaded area when possible and avoid contact with pool chemicals. In areas with very severe weather, it's not a bad idea to cover them with a plastic bag so when spring comes and you spark up the barbeque, the music will be ready when you are.

43 Questions asked on 10" Dual Woofer Outdoor Rock Subwoofer w/ 500W of Power & Aerospace-Grade Cabinetry, Brown -RSUB300

Gina • 12/17/2019, 2:17:43 PM Q These speakers have a 10" reflective woofer + 8" woofer. It comes with 2 speaker wires and I've connected them both but only the 8" woofer is working.
Customer Service • 12/17/2019, 2:17:43 PM
A The 10" woofer is a reflective woofer. The 8" woofer is the one that receives power. The purpose of the reflective woofer is to create resonance & improve bass response.
milton grice • 12/17/2019, 2:17:43 PM Q To you hook both speakers wires together into the subwoofer amp
Customer Service • 12/17/2019, 2:17:43 PM
A You just hook up one set of wires (+ & -) to the sub amp output. Only one woofer is active, the other woofer is reflective.
Rick • 12/17/2019, 2:17:43 PM Q Are these two speaker units joined as a unit, or are they separable? If they are separable, what are some location guidelines on locating the subs.
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Rick: This is a single unit that features an internal 8 inch woofer and 10 inch passive radiator that operates as a reflective driver. It comes in two differnt colors, Granite Grey and Sandstone Brown. TL
Jamie • 12/17/2019, 2:17:43 PM Q Is this a powered subwoofer?
Customer Service • 12/17/2019, 2:17:43 PM
A HI Jamie: When you see in the features Power Handling: 500 Watts, it usually means the Subwoofer is not powered. If it listed Power Rating: 250 watts RMS as an example then it would be telling you it is powered. So no this is not powered. TL
Robert Melvin • 12/17/2019, 2:17:43 PM Q How is the Subwoofer connected - connected from the receiver - Does this have speaker line level in and out for the Highs to go to the additonal satellite speakers or just speaker wire connections + / or left and right inputs? What is the recommended average RMS power form the amp Does this hae a speacker volume control to icreae the bass?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Robert, Unlike the OMSUB200, this does not have a built-in crossover that would enable you to do the sub-sat systems you describe. The ideal RMS for this Rsub300 is 250 watts. The volume would be controlled on the sub amp used to power it or the receiver the sub amp is connected to. CL/MA
