    DIY coaxial
    I've decided to make my own sub and digital coaxial cables. I've been looking around and all the digital cables I find are listed as 75ohm. To make a 75ohm cable am I looking for certain connectors or certain cable? I was looking at using this for cable:

    And this for connectors:

    None of them list impdenence, would these work alright, or should I use something like this

    For video applications you'll need a cable with a 75 Ohm characteristic impedance. Chris White has a very nifty site describing the construction of these cables here http://white.hometheatertalk.com/diycable.htm. Canare makes reasonably priced cables and connectors for this application. However their tooling is very expensive. You can do just as well with the Paladin crimper and die. More info can be found here: http://hometheatertalk.com/httalk/vi...hlight=paladin. I'd still recommend the Canare cable stripper though.

    thats what I kinda figured. I think I am going to go with solder connectors though because I dont feel like buying a bunch of tooling to use once.

    Your first choice for coax cable (DAYTON PRO MICROPHONE/SIGNAL CABLE) is not ideal as subwoofer/digital cables due to having only one layer of [braid] shielding.

    And your second choice (1694A) although ideal for digital applications, don't make a good audio cables due to their foil/braiding shielding....which is not too effective against "audio frequency range" noises/interference.

    Your better choice (for all purpose use) might be RG-59 Belden 1505F coax cable. Ideal for subwoofer cable due to their double braid shielding, and do a good job as digital cables also :)

    After looking around a bit I found this for the subwoofer and digital audio cable:

    And this for my Component cables:

    A little better choice? How does that stack up against the Belden?

    What would be a good RCA plug, comparable to the Canare crimp connectors, but solder type. I am pretty good at soldering and really dont want to spend a ton on a crimper.

    Canare LV-77S coax cable is also good cable for all round use. But also note that since they are RG-6 type coax, they might be little stiff and thick.

    For RCA connectors, the one you were looking at Partsexpress is a good one. Also look at this site where you can buy [hand] assembled cable for the type of cable you were looking at :)
