I have a pair of definitive technologies 7004's for my left and right speakers. I just bought them from a guy on craigslist. He says he had no problem with the sub's.
I'm not using the optional LFE input on my pair of mains. My reciever has my mains set to large, and sub is set to none. One sub works in one tower and not the other.
When I plug the bad tower into the wall, i can hear the amp 'pop' like the DT site says is normal. the red light is on, on the back, which signals the amp is on. however the sub doesnt ever activate. no vibrations. If i take my other 7004 and swap it in place, using the same speaker connection and electrical socket, the sub works fine.
This tells me the amp is ok? but something else is messed up? How do I troubleshoot this? I'm afraid to unscrew the back plate and mess something up.
when I transported them in my car on the way home I had the speakers resting on their backs. I was afraid to rest them on their sides since they have speakers on the sides.
On the back of this tower the level knob axle was a little bent. meaning when you turned the knob it wobbled a little. I bent it back straight and it feels like it funcitons just like the other tower. the knob is still turning something in there. it doesnt 'feel' broken.
any help would be greatly appreciated!

Yes - you have the sub-woofer. It is a powered sub-woofer with a built in amplifier for both itself and a pair of small satellite speakers. Frankly, given the low cost of the whole system it may not be worth selling on ebay due to the high shipping costs of such an item, but I imagine you could get $30 for it or so on local craigslist or something, assuming you have no use for a sub-woofer...
On the back of the sub woofer you have two sets of binding post / some have spring clip terminals ( red & black ) labeled Speaker In ( sometimes High Level In ) and Speaker out. Take 2 pairs of speaker cables and connect one end to the speaker out socket of your amplifier ( left & right ) . The other end of the cable should be connected to the sub woofer's Speaker In socket , Red to red and black to black. Now on the Speaker Out socket of the sub woofer connect your existing pair of speakers using another pair of speaker cables. If your sub woofer has a Hi Pass filter built in , you may not hear bass coming from your existing speakers with this kind of connection. Good if you have small satellite speakers.
Alright i had a chance to look over things, this is how you are going to hook up the sub. first we'll be connecting the surround sound unit to the sub woofer. surround sound unit sub woofer left front: positive (+) <-----to------------->(+) left speaker level in negative ( - )<- - -to- - - - - - ->( - ) left speaker level in
right front: positive (+) <-----to------------->(+) right speaker level in
negative ( - )<- - -to- - - - - - >( - ) right speaker level in
now that the surround sound unit is connected to the sub woofer you will need to connect the front surround sound speakers to the sub woofer. sub woofer front surround sound speaker left speaker level out (+)<-----to--------> (+) left front speaker left speaker level out( - ) <- - - to- - - - ->( - ) left front speaker
right speaker level out (+)<-----to--------> (+) right front speaker right speaker level out( - ) <- - - to- - - ->( - ) right front speaker
Alright now that the wires are all over the place and plugged in turn everything on and see how it sounds. let me know if everything is working as it should. if you need help with anything else or if something does not seem right please feel free to contact me via e-mail or phone Mark Woodring
Okay! all ceiling mounted speakers. I don't know about 4 pair of speakers.Here is the load down: First pair of ceiling speakers would be left and right front from speaker A or Main output behind your receiver. Second ONE,but a pair would be connect to the center channel output as your center speaker. Another pair would be connect to the surround sound left and right(NOT surround BACK left/right.) Now,you have 5 channel setup at this point,you still need to purchase a power subwoofer to the SUB PRE-OUTPUT behind your Denon receiver.
For Zone two,you would need to connect your other pair of speakers to surround BACK left and right output. Go to your Denon MENU button,depending on which model you have,some of them will have an on-screen display feature(you would need to have a composite video cable connect from the video output behind your receiver to the TV video input in order to use the on screen menu.)If not,you would have to it view on the front panel of the A/V receiver. You need to read the detail on how to setup the video and audio as well as distance and DB for the receiver through the menu button. I will be frank with you,if you are an amateur,Denon is NOT easy to be setup on the first time. solutiondoct
In general, there are two ways to hook up your sub-woofer. First using the high level outputs from your receiver ( speaker output from the front R & L speaker terminals ) run a set of wires from the outputs to the speaker inputs on the sub-woofer, you do this in concert with the speaker wires going to the front R & L speakers which you then attach to the R & L speaker outputs on the sub woofer amp. Note that the sub woofer doesn't power your front speakers, the connections from the sub amp are just a pass through connection where the signal needed by the sub is parasitically taken from the inputs. Second is via a low level output from your receiver / amp to the low level input on your sub amp. This is normally done via a RCA type of patch cable and connected to the sub woofer RCA jack on the rear of the source receiver or amp, Next run the patch cord to the sub amp an into the RCA jack input. IF you have a right and left input, use the Right input.
You should be able to use any of the "bookshelf" speakers to replace the Front Left/Right and Rear Left/Right. I would go ahead and get a dedicated Center speaker. I bought a Pioneer center speaker and a pair of KLH 3-way bookshelf speakers at Radio Shack at low prices. I also bought a pair of Insignia 3-way bookshelf speakers. I put this all together with a Durabrand Home Theature system (dumping the satellite speakers). There is better range and a much fuller tone with these speakers versus the originals. Even if you hadn't lost the speakers, I would recommend this as a good upgrade.
Hope that helped.
