Doug • 12/17/2019, 2:17:43 PM Q In the advertisement it said just to plug my current speaker wires into the subwoofer and the crossover will do the rest. I only have a red and a black wire coming out of my receiver now and on the bottom of the subwoofer is three (3) sets of wires. What do I do with the other 2 sets of wires? Thanks if you can help. Doug

A Doug: The optimum setup is to wire directly to the OM-SUB200 subwoofer with the four conductors coming from the Receiver/amplifier (L & R +/-) to the input of the sub. It is best to use a single four conductor cable for this connection.The internal crossover directs the low frequencies to the internal sub and sends the high frequencies to the the left and right (+/-) output which you connect your satellite speakers. Use a single 2 conductor cable for each of these connections.This makes the two satellites more efficeint not having to produce the low frequencies. The ultimate Sub/Sat system. Note: If you already have your satellites connected through an output A from your reciever/amplifier you can then connect the OM-SUB200 to speaker Output B and not worry about the two outputs of the sub. The Satellites will produce bass to their rated frequency response (typically 50Hz). The OM-SUB 200 will just enhance the lower Bass . TL
byron • 12/17/2019, 2:17:43 PM Q how do it connect this to a denon avr 1912?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Bryon, You can connect it directly to the Denon receiver from the Zone 2 output, which is listed as "amp assigned." This way you are using the internal power from the receiver (see page 68 of the Denon owner's manual). Then you can connect two full range speakers to the subwoofer to create a sub-sat system (check page 83 of the Denon manual for additional information). CL/ MA
paul • 12/17/2019, 2:17:43 PM Q I just bought this sub and 4 eight inch outside speaker. I'm hooking up the 4 speakers to speaker a on my receiver and want to connect the sub to system b. can i use two wire to go to the sub?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Paul, The best way to connect the OM-SUB200 is to create a sub-sat system (subwoofer/satellite). Connect the Speaker A output (both right and left) to the Speaker inputs of the SUB200. Then connect two of the 8-inch speakers to the speaker output from the SUB200. The SUB200 features a two-way crossover that separates the low frequencies used to drive the SUB200 and outputs the high frequencies to drive the satellite speakers (the 8-inch stereo pair). The 8-inch satellites (connected to the SUB200) become much more efficient because they only have to reproduce the mid and high frequencies. The 8-inch features its own crossover separating the signal between the 8-inch mid bass driver and the tweeter. In essence, you have created a three-way system. Connect the second pair of 8-inch to the Speaker B output and then compare the sound between the two systems (A vs B). I am confident you will want to add a second SUB200 to create a sub-sat system on speaker B as well using the second pair of eight inch speakers. Otherwise you can connect the sub directly to output B per your original question and then compare the speakers with and without the sub by turning B on and off. Make sure to run a 4-conductor wire to the SUB200 (right and left, +/-). Good luck and thank you for purchasing from OSD. TL
Scott • 12/17/2019, 2:17:43 PM Q I am trying to decide between the OM-SUB200 and the OM-SUB300. I see that the low end range on the sub200 is 50Hz while the SUB300 is 20Hz. I have 4 RS660-OM rock speakers. With the Sub200 i would run one pair as sattelites off of the sub and the other directly. I am using the SW-RX5502 receiver to a SSVC4 speaker selector. How much difference will I hear between the two subs? Is a sub amp required for the SUB300? Please provide some advice.
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Scott: Our recommendation would be to add a second OM-SUB200 and run two sub sat systems, combining a pair of the RS660 for each sub. The net result would be two, three-way sub sat systems. I am a little confused about how you are using the SSVC4 since the SW-RX5502 features four independent outputs that can be split to A&B for zone 1 (your outdoor system) and C&D for your second zone. If you are looking to add volume controls, why not add an OVC100 per each sub sat system possibly connected to the A&B output from the receiver? You can then use the SSVC4 connected to the C output on the receiver (if you are still looking to drive additional zones). I believe adding a dedicated OM-SUB200 to each pair of RS660-OM is more practical than adding the OM-SUB300, which would require purchasing our SMP250 subwoofer amp to power properly. Please let us know what you think. Maybe tell us about the rest of the system you want to connect. Note: you have 30 days to decide if you can use everything you purchased from us.
Steven • 12/17/2019, 2:17:43 PM Q I am considering purchasing two of your products, 1) the OS790 HD 8" True 360 Omni Ground Speaker and 2) the OM-SUB200 Outdoor Omni Subwoofer. However, because of my application, I would like to see more technical specs, specifically a diagram/picture of the wire connectors for both the speakers and subwoofer. I looked on line for a users manual, but could not find one. Do you have anything available for me to review?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Steven, We are placing an image on both the OS790 and OM-SUB200 that will feature hookup for the Sub Sat system. The OS790 has a Frequency Response of 42Hz to 20kHz and the Sub200 is rated at 50 to 250 Hz. The Sub Sat system allows more focus by the OS790 to produce frequencies above 250 while the Sub is dedicated to Low Frequencies only. Having a dedicated subwoofer in line with the satellite speakers provides more total output, which is especially important for wide open spaces. TL/MA
