Features & Specifications

Features:




• 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.

Does this subwoofer work with the wireless rock speakers
1 Answers
Hi John : There is no current interface to make this sub work with any wireless speakers on the market neither Bluetooth or WiFi. Typically the ones we have sold had the receiver and two channel amp built in all with a Master with the internal Receiver and Amp and then a single output to the satellite speaker. TL/4283

How would I wire 2 of the RSUB300's to a single SMP250?
1 Answers
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

I have a Dennon AVR-1800 receiver which I have 6 TIC outdoor speakers coming off of and would like to add some bass. Would my receiver handle this and would this give me the bass I'm looking for? My backyard is 100' x 100'. Also is there an 8" and 10" speaker in each Rock? What would you recommend I get. It looks like I'll need an amplifier to run the speaker also. Thanks
1 Answers
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

We have a fairly large back yard. What is the recommendation for area coverage?
1 Answers
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

September 28, 2017
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 Answers
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

April 29, 2017
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 Answers
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

Fuad
from Smyrna, GA asked:
April 25, 2017
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 Answers
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

i have a 120 watt 2-channel Yamaha receiver. Will I be able to wire this subwoofer to that receiver and the LS3-PE landscape speakers or will I need a dedicated subwoofer amplifier?
1 Answers
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.

April 10, 2014
I have a onkyo txnr626 receiver that I just purchased with klipsch aw-650 speakers. I would like to add a outdoor subwoofer to this setup and am interested in the rsub300. I haven't set anything up yet but plan on doing so in the next week or two. My question is if I need a separate amp or if I can just wire the sub into the receiver I bought. Also, will one sub provide enough bass? I am looking for a nice clear sound. Nothing that will obnoxiously shake my deck and disturb neighbors, but something that will compliment the speakers nicely. Please let me know. Thanks!
1 Answers
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.

James
from AZ asked:
April 6, 2014
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.
1 Answers
Hi James, That's a good question. Subwoofers only deal with mono frequencies so the series wiring is to sum the left and right channel into mono information. CS 2600

1 Answers
Hi Donnell, One thing to keep in mind is the RSUB300 does not have a built in crossover to separate the high and low frequencies. It is best to get a dedicated subwoofer amp for RSUB300 as that will have a cross over for the sub. I recommend the the SMP250. CS 2568

1 Answers
Hi Jim, I believe we spoke over the phone and cleared this up already, but I'll post this in case anyone else is wondering. If you aren't going to run an additional amp to power the sub, you would want to go with the OMNI Sub because it has a crossover built into it to filter out the highs. The Rock Sub requires an amp with the crossover. Thanks! -BM 2512

Hi Waverly, The RSUB300 has a 500w power handling so you will be able to run it with your Dayton amp. Keep in mind, however, it has a 4ohm driver with two speaker wires coming from it. This will allow you to wire it in series to your amp, bringing it up to an 8ohm load. There is a diagram under the pictures on the product page that shows what I'm referring to. Thanks! CS 2480

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
Customer Service - Q&A
on March 9, 2012
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

Very nice addition to the back yard.
Last year I ordered two of these speakers for my large back yard. They sound so nice I ordered two more to replace my non-rock speakers. Now I have 4 woofers in my back yard in addition to non-woofer speakers. My back yard sounds like I have a professional DJ at all times. I have these speakers about 30-50 feet from each other (one in each corner of the back yard). It's way overkill but the sound can not be beat.
