amishseagull Posted May 10, 2015 Share Posted May 10, 2015 i'm ready to insert these speaker wires into the receiver, i tried looking up what a/b speakers meant but have been unsuccessful so far, can anyone tell me which one goes where?

Sidney Crosley Posted May 10, 2015 Share Posted May 10, 2015 A/B refer to two different sets of speakers. As in, you could have one set in one room, and then run some to the other, and you'd likely have an A/B switch to select which speakers. It looks like your speaker is set up for bi-wiring. I don't know a ton about this, but my understanding is that it would allow for the tweeter to be fed by one cable, and the woofer to be fed by another so that the sounds can be sent in a clearer way. You'd likely need an amp set up for bi-wiring to use both of those, and it's definitely not necessary. So unplug one of the two speaker cables from the back of the speaker, and put the other ends into the A inputs. Do the same on the other speaker. Make sure your amp is set to A speakers. You should be good to go. Quote Link to comment Share on other sites More sharing options...
Tardcore Posted May 10, 2015 Share Posted May 10, 2015 there should be metal pieces that connect the black/black and red/red terminals on those speakers. put them back in, if you still have them. otherwise, cut a piece of your speaker cable to make a new one. kjkenney 1 Quote Link to comment Share on other sites More sharing options...

You should be good to go. This is right but it describes bi wiring which as raindogtrombone says is pointless. Your amp though can do bi amping which is a totally different thing and not at all pointless. The only proviso is that in bi amp mode your amp wants speakers that are 8ohm or higher so you need to check what your speakers are rated at. If they are 8ohm then all you need to do is wire the left side top speaker terminals red and black to the amp left A speakers terminals red and black, then wire the left side bottom speaker terminals red and black to the amp left B speakers terminals red and black, then do exactly the same on the right side. You need to make sure red goes to red and black goes to black and then make sure that both A and B speakers are switched in on the amplifier and you will be bi amping. You might get away with it if your speakers are 6ohm but the amp might run hot or cut out if you run at high volumes for a long time so I wouldn't recommend it and defiantly don't do it if your speakers are 4ohm. If you get any of the pairs wrong like top red and bottom black together then it wont work and you could do damage so be careful and make sure it is wired right before you turn the power on. If you get the top and bottom pairs swapped or don't have both speaker sets turned on at the amp then it will just sound shit, all treble or all bass. And lastly and most importantly do not put links between the speaker terminals if you are bi amping as this will definitely make smoke, the links are for if you are not bi amping which is the usual way to run things. And never put links in the amplifier terminals. Quote Link to comment Share on other sites More sharing options...
Sidney Crosley Posted May 10, 2015 Share Posted May 10, 2015 What are the advantages of bi-amping? I was impressed enough with myself that I could mostly answer the OP's question, but I still have a bunch to learn! Quote Link to comment Share on other sites More sharing options...
allenh Posted May 10, 2015 Share Posted May 10, 2015 Bi amping is what dual wired speaker crossovers are intended for and as you rightly say one set for bass and one set for treble with the intended gain being in clarity but its one amplifier for bass and one amplifier for treble. Somewhere along the line some idiot and probably something to do with HiFi or cable making suggested bi wiring which is wiring one amplifier to the two sets of speaker connections which is completely pointless and if you bi wire rather than using the speaker links all you are doing as adding more cable and therefore mor resistance to the signal path which is only good if you make or sell speaker cable and plugs. A lot of amplifiers with A\B speaker outs can be used to bi amp but as with the OP's his is actually a 2 channel amp that shares its outputs for A and B, the giveaway being the different speaker impedance requirements when running one or both sets of speaker outputs. The better units have four distinct speaker outputs to run the A and B sets and an amp of this type does not have different impedance requirements when running one or both. Interestingly although I'm not a fan of surround sound receivers for hifi a lot of the 7.1 units when run in 5.1 or stereo mode are intended to or can easily be made to run in bi amp mode for the front main speakers which is how I run mine, my fronts are actually meant to be run in tri amp mode which is another game altogether.

amishseagull Posted May 10, 2015 Author Share Posted May 10, 2015 i wired it correctly and set the receiver to A+B mode, but the sound is sort of muffled, receiver is onkyo TX-8020 and speaker are polk audio RTi-A1 bookshelf Quote Link to comment Share on other sites More sharing options...

amishseagull Posted May 10, 2015 Author Share Posted May 10, 2015 So you're using 2 sets of speakers? no just one, i thought i had to set it to A+B mode oops, A mode and B mode sound worst than A+B Quote Link to comment Share on other sites More sharing options...
dethrock Posted May 10, 2015 Share Posted May 10, 2015 no just one, i thought i had to set it to A+B mode oops, A mode and B mode sound worst than A+B It sounds like you still don't have things set up properly. Google "hooking up speakers to receiver" and look at pictures of how it should be wired. I don't mean to be rude but this should be extremely simple. kjkenney 1 Quote Link to comment Share on other sites More sharing options...

kjkenney Posted May 10, 2015 Share Posted May 10, 2015 post a picture of how its setup with the wires connected. assisting someone shouldn't be like pulling teeth. "I did that" is far too little info to tell us where you're at now Quote Link to comment Share on other sites More sharing options...

amishseagull Posted May 10, 2015 Author Share Posted May 10, 2015 the wires are put in the correct places, i'm thinking it's an issue with compatibility with the speakers and the receiver, if not i'll have to re-wire it again Quote Link to comment Share on other sites More sharing options...
kjkenney Posted May 10, 2015 Share Posted May 10, 2015 so it looks like you have one speaker using all the ports on the A section and the other using all the ports on the B section, yeah? Go back to what Tardcore was saying and put a jumper wire between the posts on the speaker to complete the circuit; red to red and black to black and hooking one of each to your receiver. One black and one red for your left and same for your right speaker. All on Channel A on the receiver. And then you SHOULD be good Quote Link to comment Share on other sites More sharing options...
dethrock Posted May 11, 2015 Share Posted May 11, 2015 Why do you have one speaker hooked up to A and one to B? Hook them both up to A.

kjkenney Posted May 11, 2015 Share Posted May 11, 2015 its not bi amp if you only have one receiver Quote Link to comment Share on other sites More sharing options...
dethrock Posted May 11, 2015 Share Posted May 11, 2015 Is bi-amping what you're trying to do? Did you actually state that anywhere? Does it sound fine if you hook up the speakers normally? Sorry i thought hooking them up the standard way is what you were trying to do. Quote Link to comment Share on other sites More sharing options...
kjkenney Posted May 11, 2015 Share Posted May 11, 2015 Yes because bi means two. So bi amping means you have two amplifies power sources, one for the high and one for the low end. Quote Link to comment Share on other sites More sharing options...
Tardcore Posted May 11, 2015 Share Posted May 11, 2015 1) Get rid of that second set of cables (A only or B only) 2) Put the terminal bridges back in. 3) set your amp to A or B as appropriate. Bi-amping requires 2 amps. You only have one amp. Having it wired the way it is now is just taking the long way around to make everything sound worse or possibly not work at all.

Sorry i thought hooking them up the standard way is what you were trying to do. it wasn't, someone mentioned it and i guess i misunderstood something anyway, i did this now: and it still sounded bad however, i unplugged the rca cable from phono to dock, and now it sounds very clear Quote Link to comment Share on other sites More sharing options...
