Features & Specifications


• Heavy-duty weather-resistant outdoor subwoofer puts bass in the backyard, porch, patio or poolside to complete your outdoor surround sound system
• Rated at an 500W, includes a 10-inch reflective woofer and an 8-inch subwoofer to crank up powerful low frequency sound effects for backyard sound systems
• Rock-shaped outdoor subwoofer blends easily in the backyard landscape and is built tough to withstand rain, snow and high temperatures due to the specially coated aerospace-grade multi-layer composite cabinetry
• Turn your backyard into party central with the best outdoor subwoofer for the price that not only looks incredibly real but does not need to be buried like traditional outdoor subs
• Enjoy outdoor movies during warm summer months with true surround sound with this all-weather subwoofer that can be purchased in canyon brown or granite grey to match your backyard landscape

OSD Audio’s RSUB300 is a non-powered outdoor subwoofer that delivers gut-wrenching bass with a whopping 500W of power. 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.

HI, is the rsub300 Omni directional or it needs to directed towards the audience?  Also how far apart can these be placed from each other if i order two.  I currently have two sets of outdoor speakers

speakers and would like to add a sub to each set.  I would also purchase the smp500 amp for the two subs.  I am currently using two of the new sonos 250 w amps and would like to implement

subs with my outdoor setup.  i currently have two sets of speakers facing each other and they are approximately 70 feet apart.  I would also like to know weather i should use a 2 or four conductor

 outdoor cable going to the subs from the smp500 amp.  any help is greatly appreciated. 

1 Answer
Hello Doyle:

The RSUB300 Rock Subwoofer is not Omnidirectional. The ideal location (starting point ) would be between the pair of outdoor speakers. I would connect the speakers before you bury your wires, placing the sub in a couple of different locations to which one sounds the best. Are you playing the same music for both SONOS power amplifiers? I am assuming you are purchasing a single SMP500 to supply power to both RSub300 but have only one mono sub connection from the SONOS to the SMP500. Are you looking for more power for each pair of outdoor speakers, or do you want to be able to play two different sources? If you want a sub for each SONOS Amp, then you would need two SMP500. But if you are playing the same source from both SONOS Amps, then you can connect a single SMP500 to one of the SONOS with a Mono Sub Cable from the single output of the SONOS. You can either connect to either the Right or Left RCA Input of the SMP500. Or you can add an RCA Y Adapter Cable 1Female to 2 Male connectors. I would also recommend 12 gauge, two conductors, CL3 rated direct Burial Speaker Cable from the SMP500 to the RSUB300. Check out our Aqua Blue connectors to terminate the cables to the RSUB300 connecting cables. I would try placing the sub in a couple of locations and listen to it from the most optimum listening area. You can determine if one is enough or if you want to add a second. The second sub can either be wired from the first RSUB300 or wire the second Rock Sub back to the SMP500 Sub Amp and connect both cables to the Speaker level Outputs (+/-) with the 12 Gauge. Note; determine your optimum location for both subwoofers before you mount to their permanent positions.

Good luck, let me know if you need additional help;

I have a sony dh550 and DENOn  avrs730h would either of these receivers power this subwoofer?

1 Answer
Hi Frank:

I do not believe you will be able to adopt either of these Amplifiers to power the RSub300. One the SONY at 90 watts or the DENON at 75 watts has enough output for the outdoor subwoofer. Typically you would need a dedicated sub amp like our SMP300 or SMP500. But I am curious about your overall setup including Home Theater and your complete outdoor system. I am trying to figure out if you are creating an outdoor home theater or a 2.1 channel stereo setup with a Sub. is my email address if you want to discuss further.

I have an existing system of (6) RX805's powered by an AMP200. I am looking to add one RSUB300 now, but future-proof the install in case I want to add a second RSUB300 in the future. Would the SMP300 or SMP500 be most appropriate if I want to add one RSUB300 now and MAYBE a second one later on?
1 Answer
Hi Angel:

The SMP500 would be a better choice for the single speaker and even better for driving two of the subs at 4 ohms. It features an IR remote control and DSP effects with more than double the power. Note: You also have a performance Guarantee for the first 30 days on the RSub300. This design is more than ten years old, and we have since two new passive outdoor subs, one being the GLS8 in-ground sub and our FORZA 10 a down firing deck sub.

Good luck

I have a 20x40 ft pool, currently I have 2 pairs of Bose 251’s facing each other being powered by your 200watt amp and being fed by your preamp. I want to add some bass to the setup. I’m trying to decide on these rock subs or the yellow buryable sub. I would buy your digital sub amp. Which would I get more bass out of? And would I need 2 subs? In addition, would the sub amp get it’s source from line level?
1 Answer
Hi Dustin: I like the in-ground subwoofer, the GLS8 a much newer and more effective design. The SMP500 would be the best as well, and you could drive a two of the GLS8 with the single amplifier. It will run a 4-ohm load created by wiring the two subs in parallel. You could run 12 gauge wire from the amp to Sub #1 then on to subwoofer #2. We can offer you a special bundle price for the Amp, two subs, and the 12 gauge wire. Just call our customer service and tell them Tim sent you. An excellent choice for the upgrade, TL/5371

Could 2 of these be powered with an smp500 sub amp. Will it provide a good amount of power. Would i wire them in series.
1 Answer
Hi Kent: The SMP500 will power either two of the RSUB300 Outdoor Rock Subwoofer or two of the In-ground 8" Sub-woofers. In both cases, you would wire both options in parallel which would drop the impedance to a 4-ohm load and get the most output out of the SMP500. If you chose to wire in Series, the Impedance would be 16-ohm while cutting your power output in half. TL/5341

1 Answer
Hi Dan: If you are using the Sub strictly for Home Theater you will want to pick the LFE (Low-Frequency Effects). If you are using the sub to listen to music in a 2.1 or 4.1 setup you would bypass the LFE and use the controls on the SMP Dedicated Sub amplifier. TL/5143

I'm looking for a good outdoor sub, and I cant help but notice that all the reviews are not current, what can you do for me to convince me that its good sub.
1 Answer
Hi Dan: The RSUB 300 was discontinued about three years ago then recently brought back. At the same time we introduced three new in-Ground subs, 2 8" and a 12". The RSUB 300 is an 8" design with a 10" passive radiator and has been around off and on for 15 plus years. If your looking for a sub that looks like a rock this the one. Thwe in-ground subs look like a industrial mushroom with plenty of punch. Check out the GLS8 on the site or the two Subs on the OSD Premium site under the Black Series. XSUB8 (8") and XSUB12 (12") are the 2 models. You will need to call our customer service for pricing on the Black series. All four subs talked about in this reply are in stock. The dedicated sub woofer amplifier SMP250 is available (8 ohm only) or there is a Black Series Sub Amp the SAM300 (4 ohm stable which will allows you to drive two subs). TL/4859

How would I wire 2 of the RSUB300's to a single SMP250?
1 Answer
Hi Adrian: You would want to connect this in Series Parallel. You have a single positive and negative coming from the amplifier. You want to connect single positive from each woofer to the single positive coming from the Amplifier. Then connect a single negative (black) from the second input wire of each Sub 300 to the single negative connection coming from the amplifier. Then connect the two remaining open wires together (a positive red and negative black) for both Sub 300. This will give you a 4 ohm load which the dedicated Sub Amplifier should be able to handle (at least our SMP250 sub amplifier will handle this with no problem). Good luck TL/4202

1 Answer
HI Ken I believe you would need to add a external Subwoofer amplifier like our SMP250 to power the sub woofer. It could connect to the pre-amp. The sub includes a 8 inch speaker that is directly connected to the input from the power amplifier and a 10" passive radiator that is not connected but acts a s a tuned port. Good choice TL/4135

I drive it with a Yamaha receiver that I think has 200 watts. I have the speakers running to a volume control and then into a speaker switch selector box and then into the push terminals in the back of my receiver. Does the RSUB300 replace one of my speakers?

And you are lacking bass. What is the model number for the Yamaha? What Brand and model number for the rock speakers, Volume control and speaker selector?

We have a fairly large back yard. What is the recommendation for area coverage?
1 Answer
Hi A Hays: Think 8 to 12 foot for the speakers to be placed apart between right and left for proper stereo separation.. It is better to have more smaller speakers rather than depending on just few Larger speakers. Then there are choices between a directional speaker like a patio speaker or rock speaker versus a Omni speaker which gives you a 360 degree sound field. Think directional to aim back at the house and away from your neighbors. Good Luck TL/4618

Hi.. the OSD owner's manual states that the R SUB300 is an 8 ohm speaker, yet the picture on the site states that the "SUB300 features an 8 inch 4 ohm driver". Can you confirm which is correct?
1 Answer
Hi Paul: I believe both are correct except they left out 4 ohm DVC (dual voice coil). You have a right and left input connection which wires the two voice coils in series so it becomes a 8 ohm speaker. If it were wired in parallel it would be 2 ohm load which would draw lots of current and most amplifiers would not be able to handle the heat that would create. TL/4569

Hello, need help. I purchased 1 R sub300 and 1 smp250 amp. I have an older outdoor sub woofer (tree stump version) that I purchased from OSD some time ago, I believe that model is discontinued so I don't have the specs or my manual on it but I believe its an 8" 250watt 8ohm woofer. My question is how would I wire the two subwoofers (the rsub300 and tree stump subwoofer) to the smp250 amp or would I need a second amp. thanks new to this sub wiring stuff. I attach pic of tree stump sub. maybe someone know the spec for it.
1 Answer
Hi Gus: Both Subs are 8 ohm. You should be able to wire both speakers in parallel to the SMP250 which is a mono output (Positive.Negative). Just connect both positives together and then the negatives together.See if that gives you enough output. If not you could add a second SMP250. Note when you connect both amps in parallel the impedance drops down to 4 ohm and increase the output of it as well. You should have plenty of thump and more coverage outdoors. TL/4332

Hello, I have a Pioneer VSX-830-K A/V receiver that is connected to 4 RS670 rock speakers I bought from OSD, they are connected with 2 front and 2 rear Binding posts in receiver. My question is, can I connect this Sub RSUB300 to the center connection of the receiver to add sub effect I am missing from my outdoor sound?
1 Answer
Hi Fuad: There is a setting in most Audio/Video Receivers for 2.1 stereo. And you have the four RS-670 connected as 2 channel stereo. But the RS Sub 300 does not have an internal crossover and is meant to work with an amp like our SMP250 which would connect to the sub woofer output on your Receiver then to the sub. The sub amp would give you the crossover specifically for the RS Sub 300. The Center Channel output might not feature the Frequency Response you are looking for and would crossover higher than you would want. You would have to depend on the natural roll off of the internal driver. And would have higher frequencies getting through. TL/4326

1 Answer
Hi Rodney, You should be able to run the subwoofer off that receiver but I believe it would depend on the receiver's power handling capability. Can it run at 4ohm or just 8ohm? Also, if you do run this with satellite speakers, I would recommend running a volume control between the sub and the satellite speakers to control the volume of the speakers, since they will be much louder than the sub.

1 Answer
Hi Al, This particular subwoofer requires its' own mono, subwoofer amplifier to power it, as it doesn't have a crossover built into it. We do have an outdoor subwoofer that you can use with a stereo receiver though. Check out the OMSUB200. It has a built in crossover to filter out the highs and you can even run a pair of satellite speakers off of it to receive those filtered out highs. It will provide a decent amount of bass, but bass really thrives on the more surfaces (walls) it has to bounce off. If you are more interested in this rock sub, however, you would need our SMP250 to drive it. We are currently out-of-stock on the SMP250 sub amp, but it will be here in the coming weeks.

I see in the wiring diagram that there are 2 sets of wires coming from this sub that need to be wired in series to produce an 8 ohm load. I assume that means it's a dual voice coil driver? I saw that another customer asked about that you said that is not a dual voice coil, but what other explanation could there be for 2 sets of wires coming from it? They can't both be coming from the same voice coil of the same driver because then wiring them in series would just be jumping the + and - terminals of the speaker together and that would just cause the amp to short out.

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

Hi Robert: As CL mentioned the OMSUB200 might be a better choice for your application. It is an outdoor speaker but not in the shape of a rock. It does feature a Speaker Level output so you can connect a stereo pair from the Sub. The SUB200 has an external crossover that directs the low frequency to the Subwoofer and outputs the High frequencies to your staellite speakers making them more balanced with the subwoofer only having to reproduce the mid and high frequencies. Both Subwoofers are passive with no level controls. The OMSUB200 is meant to receive a full range signal from your receiver/amplifier with volume being controlled for both the sub and satellite from the receiver/amplifier. The RSUB300 is meant to be driven with a dedicated Subwoofer amplifier like our SMP250 which has a Variable Crossover knob and volume control. Note most receivers that feature a dedicated sub output are Audio Video Receivers that are powering a subwoofer as part of a Home Theater surround sound system. TL

Is this a powered subwoofer?
1 Answer
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

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.
1 Answer
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.
