Dear all;


I really like your forums, I feel it is full of information.


I am currently installing some pipes in my new home theatre. I will have some high end equipment such as the Denon 3312. I need the best wires. The room dimensions is not so big (5x5 or so...). While installing the pipes I realized that after pulling the cables, one of the speakers would need around 27 meters of cable! I am also using aroun 1inch pipes.


I am trying to think out for other options, but I am running out of time since my wedding is on the 9th os September!


Lets say I couldn't find some 'constructional' work-around, in the worst case scenario, what kind of speaker cables (good ones) will deliver the sound in highest possible quality?


I am not so good with speaker cables, I have read a lot of information in some short time (however just theory). I need to know if this is possible, and if so, would I be able to install four of the suggested cable into the one inch pipe.


thanks in advance!


Note: someone told me that I should not buy any cable that is less than 12 gauge. I would appreciate if any one can point me out to a specific cable rather than all this technical wording (volts, amps, gauge) - it sometimes can feel chinese!

27 meters (90 feet) is a pretty long way to run speakers at 8-ohms or so.


Are these distances just for the surrounds or something? If so, you might want to see if your receiver would allow you to run pre-amp outputs of those channels, and put a separate "black box" (stand-alone) amplifier nearer to the speakers. You'd likely need to use balanced line-level audio at that distance, too.


Have you contacted Denon? They may have a suggestion.

Ratman,


Thanks for the link. How do I know what is my ohm load?


Kenglish,


Actually I have my Denon 3312 receiver at the back. The back and surround speakers are ok. I have not contacted Denon. The distance is not actually far. However, because the pulling of the cable (goes up and down, up and down, etc).


For me: worst case scenario, I'll just pass the cables under a thick comfortable carpet all the way to the three front speakers and will never notice them. However, I do prefer pulling the cable with that distance in that wall, given that I have already installed the pipes in the wall (break and repair). Also, I till look neater and it will be also more reasonable and practical that way, obviously..


Appreciate your help.


Note: I have not purchased the reciever yet, I can still go ahead and buy another reciever.


Note: I just googled and found that the Denon 3312 offers 8 ohms, so according to roger russel if I buy 12 gauge cable (with my selected 8 ohms reciever) it can reach a maximum distance of 120 feet (36 meters). Correct
?

I was wondering if anybody knows if there are special adaptors for the wires that go into an old Pioneer Plasma PDP RO4U 40" TV. I have wires with jacks currently running behind the wall but can't get the special HDMI cable that came with the TV behind the wall. Ideally I could attach the cable to the existing cables and have another adaptor at the other end to plug into the monitor itself. Any suggestions?

Hello Ratman, your links certainly educated me!!!!!!!!


Reading through all the above, I think I am so close into ordering:
http://www.monoprice.com/products/pr...#specification


Because the over all distance of all my 7 speakers is about 135 meters.


I hope there will not be sound out of sync, considering one speaker will be at 4 meter distance (back surround) and front speakers will be at 27 meter wire distance!

No problem at all.

Thanks alot Ratman.


I was tempted to buy some monster cables, assuming it is the best. But it seems that is not necessarily true.


I hope the one inch pipe will fit three of the above cables. I think the dimensions will be ok.

Conductor resistance (20 ℃) Max: 5.43Ω/KM

Insulation resistance (20 ℃) Min: 0.75Ω/KM



Does this mean if the temperature of the walls go over 20 degrees the cable will go faulty :O !


I live in Qatar, ie hot weather, plus I do not like to set my room temperature ( with ac's) to be below 23 degrees Celsius, i freeze at that temperature!

(20 ℃) is the just standard temperature for many lab tests. All copper wire changes resistance (very slowly) with temperature at the same rate.


If the temperature gets above (60 ℃) you can start to worry.
