Features & Specifications

The OSD Audio AP650TT 6.5-Inch Stereo Patio Speaker, which is available in black or white, is the perfect way to outfit your space with superior sound quality. Featuring gold-plated, spring-compression binding posts for optimum connectivity and a dual voice coil, twin-tweeter system helps you cover the entire listening area with high-quality sound. Even at low listening levels, the AP650TT cranks out plenty of bass, too.

What Is a Dual Voice Coil Speaker?
A Dual Voice Coil (DVC) speaker uses a special voice coil cone design that allows both channels of a stereo system to drive one cone. Sound complicated? It's not. Basically a DVC speaker plays both right and left channels through one speaker cone. You get both channels but without the acoustic separation that happens with two speakers. DVC speakers are great space savers and customers love them for bathrooms, hallways, small patios, etc. They're also great for outdoor areas where stereo separation is not always a big concern.

· Rust-resistant aluminum bracket for mounting versatility
· Gold-plated spring compression binding posts for optimum connectivity
· Sturdy ABS polymer frame
· Power-coated rust-resistant grille


What does the 16/8 ohm switch do?

The 16/8 ohm switch allows you to use the speaker as a single point source Stereo speaker when you need only one speaker but have a stereo signal coming into the zone/room. The switch is set to 16 ohms when you are connecting both voice coils (there is an input for right +/- and left +/-). The second option allows you to connect two AP-650 speakers as a stereo pair. In this application you connect only one voice coil of each speaker and set the 16/8 ohm switch to 8 ohm. In this case both tweeters still play which in essence doubles your tweeters providing additional coverage in the zone/room versus a standard pair of 6.5 inch 2-way speakers. See attached images showing diagram for 16 or 8 ohm connection.

Would 2 pairs of these be a good fit for outside using the XMP100 amplifier? I'd like to have 4 speakers in all 4 corners of my patio cover for TV and chromecast audio (phone and Google Home) music use?
1 Answer
Hi Jason: These would work perfect for your application for 4 each of the AP-650TT and a XMP-100 amplifier. The XMP-100 features automatic source switching where you could connect the Google Chrome cast to the Main input and the TV to the interrupt input. I am assuming you will be playing audio most of the time and that will play until you turn the TV on which takes priority coming on instantly. Once you turn the TV off the output switches to the Main input after a five second delay. The AP-650TT features a 8/16 ohm switch. For your application you would connect a single voice coil of each AP-650TT and make sure the switch is set to 8 ohm x 2. Both tweeters will play. You will have two stereo pairs (right and left).

I was advised to use this as a centre channel with ap560 5.1 system. But my receiver only has one set of centrechannel posts.This means I am only using one of the two voice coils?if so why not one more ap650 for the centre?
1 Answer
HI Garry: It is OK if you connect just one input, just make sure you set the 16/8 ohm switch to 8 ohm. Even thought only one voice coil is connected both tweeters are working and the AVR is seeing the 8 ohm matching the other AP-650 pair for your front stage. All three speakers have identical timbre match since tweeters are identical and woofer cone material is the same as well. The dual tweeters give you a little bit better dispersion for the center channel (not a bad thing). The application (16/8 ohm) switch allows these to be used as single stereo summed mono speaker, or stereo pair or in your case a single center channel makes these speakers very flexible. TL/3906

Can both speakers be wired together on a single channel?If so, how would one set it up so it is safe for the amp?
1 Answer
Hi James: There is a 8/16 ohm switch on the AP-650TT. You would set the switch to 8 ohms and connect just one of the two inputs. You then run a 2 conductor cable out of the same input that you connected from the amp then run it to the second speaker and connect only the single input (either one) of the second speaker and set the switch to 8 ohm as well. Big question are you bridging (mono) your amplifier so you have a single mono output. Problem is most of the time when you bridge the outputs of your amplifier the amp likes to see an 8 ohm load. The setup I suggested will give you a 4 ohm load with the two speakers paralleled together. If you could run normal stereo four conductor output you can parallel a pair of the AP-640TT connecting both inputs in parallel and setting the 8/16 switch to 16 ohms. Your amplifier should see a 4 ohm load again but if it is not bridged you will not be pushing the amplifier as much. What amplifier /receiver are you using; and what else can you tell me about your setup? TL/4393

I want to use this speaker outside in a very load environment. Will they hold up to long hours at hi volume without burning out?
1 Answer
Hi Greg: These are excellent speakers that will have no problem playing loud. The real question is what and how good is the amplifier you are planning to use with these. Also are you planning to use it as a single stereo speaker or will you be using multiples. How critical is it for stereo separation, if your are using multiples how far apart will they be? I would like some more information on your system and application. If you can supply me with the brand name and model number of your components I could probably be able to provide you more complete answer.

Can I run the L/R channel from my receiver to an outdoor volume control and then run the wire to two of these speakers? Would it better to run the speakers in series from the volume control or parallel?
1 Answer
Hello Jon, Since this is a dual stereo speakers, it's like running a pair of speakers, so you would need 4 conductor wire going from your receiver to the volume control. Then, run 4-conductor from the volume control output to the speakers input.

I have a Panasonic home theater with 3 ohm front speakers (all of them, not just center channel). Since this is 8 ohms, will it burn out my home theater because it has to drive more current or is it that I'll have to crank up the volume (potential distortion) to get reasonable volume? Thanks!
1 Answer
Hi Rob, Is it your actual receiver that is only rated for 3ohm? That must be an unusual receiver, as most home theater receivers are built for 8ohms. Is this the type of system that came with its own speakers? I think it would be risky trying to run this speaker on that receiver.

Hello, Yes - these can be run off any 8ohm amp or receiver. Note that this model is a dual-tweeter speaker. In other words, it's basically two speakers in one, so you run two wires to the back of the speaker.

Can multiples of this speaker be run in series from single L/R amp speaker outputs and how would this affect impedence if at all?
1 Answer
Hi Eric: You can run two pair of these speakers in series. It will raise up the Impedance to 16 ohm that the amplifier will see.Most amps/receivers are not recommend going higher than 16 ohms. What are you connecting to and what is your application? How many speakers are wanting to ultimately connect? The issue with 16 ohm is your are cutting your output power from the amp/receiver more than half. You may find that in order to get enough volume you may overdrive the Amplifier. You could run the speakers in series parallel to keep the impedance at 8 ohms but depends on how many speakers you are connecting. Please let us know more about what you are trying to accomplish.

I am planning on mounting this speaker to my dock which is about 20" or so off the water surface. How water resistant is the speaker? Also If I am reading this correctly I would not need 2 speakers but rather one speaker per area I am looking to have sound coverage is that correct? Thanks, Greg
1 Answer
Hi Greg, While these are outdoor speakers, we do encourage our customers to add as much protection from direct weather as possible. For instance, if they were being mounted on a patio, we would recommend having them under an eave so rainfall doesn't have direct contact. The speakers are built with weather resistant materials, but they are not 100% water proof. The speaker housing is plastic, but the grill is metallic. While it's coated with a rust-resistant paint, under the right circumstances, rust can occur. The brackets are aluminum so they won't rust. Correct! Since this is a dual-tweeter speaker, it will provide stereo sound, rather than needing a pairing speaker in each area. Let us know if you have any further questions. Thanks. -BM 2579

I want to add audio at each outside entrance to our business and wondering if this speaker can take the environmental abuse...rain, snow, cold, heat.
1 Answer
Hello Dave, These speakers are designed with weather-resistant materials and are intended for use outdoors in cold/hot temperatures and moisture. We do recommend mounting them underneath an eave or angling them downward to give them extra protection against rain. -BM 2432
