I'm hoping it isn't too late!!!

I'm new to this whole home cinema thing and forgot to wire for my sub before the sheetrock. I did to the fronts, center, and rear speakers.

The problem, the cabinet for the stereo is about 40' linear (along wall) to the screen (opposite side of room). Does the sub need to be in the front or can I put it behind me or on the side of me?

Do they make 50' sub cables and are they expensive?

See attached doc (not to scale) of current configuration. Any help appreciated!!!

Thanks!

For some reason I can't open your attachment, so in hope that it is not critical to an answer here goes.

The subwoofer does not need to be in front. In fact that may not be the best possible placement. Very low frequencies are essentially omni-directional and the human ear does not localize them very well. That's why a sub on one side does not pull the soundstage to that side.

If you are not concerned about measuring the room response effects, you can either put it where you like (corners make it louder), or try the often suggested trick of putting the sub in your chair and moving around the room until you get a good sound. Put the sub in that spot.

Most folks just use RG6 or RG59 with RCA connectors to get the signal to a powered sub. At audio frequencies and line leve signals either will do fine. You can make one up or buy one. 50 feet is no problem.

Premade something like this will be fine http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10236&cs_id=1023602&p_id=2684&seq=1&format=2&style=

Wow, I didn't realize you could use RG6 to get sound to a sub. I have plenty left over from doing the basement before the rock hit the walls.

About the attachment. I was able to do a right click and open in new window. For some reason I couldn't open it either any other way.

Thanks for the help! If you wouldn't mind trying to take a look again, that would be great!

Man, there is soooo much to learn in this industry. Everything has changed a ton since the days of vinyl and diamond needles on my aiwa turntable! :0

I have your drawing open. You have tough room with few options.

I'm sure that you've seen suggested layouts on line or in your owner's manual, but if not the Dolby Labs layouts are here (http://www.dolby.com/consumer/home_entertainment/roomlayout.html)

For 5.1 they recommend this-

Your surround placement is not optimal, but it may not do you much good to tinker with it.

There seems to be no left wall as you face the screen, but you might find it worth your while to install some sort of sound treatment on the right wall at the first reflection point. That is the point at which you can see the speaker reflected in a mirror that is held at eye level and flat to the wall. If the room is not carpeted consider a rug on the floor positioned to cover the reflection point off the floor.

Sitting close to the back wall you may also with to consider sound panels on that wall to cut reflections. Bass traps are very helpful and you should read about them also.

There are many threads on acoustic treatments with lots to read. Ethan Winer, http://www.realtraps.com/ and myfipie (Glenn of GIK Acoustics (http://gikacoustics.com/)) are two of the experts who regularly post and answer questions. Check out the two sites for some info and then go from there.
