Josh, 1)Yes. 2) Probably eventually, but no rush. Included with your player will almost certainly be a connecting cable for audio and video about 4 feet long. You haven't mentioned your TV and at least temporarily you can use the video part of the connector(usually the yellow plug)as your coaxial audio connection, since the video connector is in fact a 75 ohm coaxial cable. 3) No. You can't use the speaker wire for the connection between the sub out on the receiver and the line-level input on the sub. You have to use a coaxial cable with an RCA plug on each end; you can get this for less than $1 a foot from sources such as Parts Express and Cable America.

Well, I have my sub, player and speakers.

I did get that cable with the player. I had the sub hooked up to the player just to listen to it, I had that cable plugged into the player's left and right inputs, and into the sub's left and right inputs.

I take it when I set my whole system up, I don't need a left and right going to the sub, just a single RCA into the right input on the sub, which says "mono" next to it.

Also on the sub are a series of 8 plugs, 4 for input and 4 for output, which have (+) and (-) for left and right on them, and I think these are for bi-wiring but I am not sure... ?

Thanks,

Josh

Another question: looking on parts express, they have listed coaxial cable, and subwoofer cable - are these the same thing?

The pictures and prices look identical.

Thanks,

Josh

Okay, Josh, lots of points; I'll try some of them. So you have a coaxial cable which is the yellow-plugged one. Use it(assuming that you don't use it for TV) for the connection from the coaxial digital output of the player to the coaxial digital input of the receiver.

Yes, you need only one RCA plug into one RCA socket on the sub. All those 8 terminals on the sub are for high-level inputs and outputs with speaker wire, which you won't be using since you're using the generally better line-level coaxial connection. The crossover control on the sub should be turned all the way up to get it out of the way of the 90Hz crossover which the receiver will do.

Most likely the sub and coaxial cables you saw on Parts Express are the same. Any coaxial cable with RCAs can be called a sub cable. As you learned by hooking the sub up with the red and white connectors from the player cable, it isn't absolutely necessary that the sub connection be with a coaxial cable, although that's what's usually suggested because it has better shielding against interference.

When I mentioned those two online sources, I didn't mean that you shouldn't just go over to RadioShack if that would be more convenient(and save shipping expenses). They'll have coaxial and other cables of suitable length with RCAs. As far as length, be sure to get it long enough to reach the best sub position, which probably is the corner. That's enough for the moment.

We had some extra CAT 5 Network cable at work so I made some DIY speaker cables for my M80's terminated with soldered on spades. I followed the TNT Triple T (search it and you will find it)design with the variation that makes the woofers get larger cables. IMO it sounds awesome. For the cost of 12 gold plated spades and some time it was definately worth it. Always bi-wire if possible too. just my 2 cents.

golfdawg,

You're going to get an earful on your "always biwire" opinion. I might as well start the avalanche, though.

Biwiring has been shown to be electrically equivalent to using one thicker wire. There is absolutely no difference -- other than the one created in your own head.

Just my (and the majority of the other regulars here) 2 cents.

The only thing about those CAT5 recipies is that the high capacitance of the cat 5 cable will oscillate some amps. Especially on longer runs.

Yeah, I probably should have kept my trap shut on the bi-wiring. You can check out some tests that cable master Jon Risch did on bi-wiring on his site http://www.geocities.com/jonrisch/page7.htm and make your own decisions. The CAT 5's do have high cap but the output stages of most modern amps don't have a problem with it.

Anyway I figured I would find out for myself since I had some free CAT 5. Anyone who likes DIY stuff should give a try and make their own judgements. I love my M80's and will leave my cable thoughts to audioasylum.com
