    I'm waiting for nice new SVS PC Ultra subwoofer to arrive, so meanwhile I thought I'd make a new cable out of some bits I bought from maplins a while ago.

    I'm no expert with a soldering iron, and I don't know whether my technique (or lack of!) will have any adverse effect on sound quality.

    Expert solderers will probably cringe at the mess, but here's some pics anyway.

    I think the cable was about £2-3 / metre, and the plugs were £2 each.
    The cable is 2 metres long, so it must have cost me about £10 in all to make.

    How much do you think something ready made of similar quality would have cost to buy?

    dunno maybe double, even trebble. Most of the time big name companies are using same cable but just whack there name on the side.

    Looks like bird s##t to me LOL, the solder looks like it as not flowed it seems to be in a blob.
    This usually happens if your iron is not hot enough or you dont hold it on for long enough,did you use any flux???

    I didn't use flux as the solder I used said it had flux in it.
    I've just found some 'lead free' solder,... should I have used that instead with some flux?

    I like your frankness, I thought it looked a bit like bird s**t too!
    Will it make any difference to the sound quality?

    Perhaps I should buy another couple of plugs, cut the existing ones off and try again..... or perhaps I should throw it in the bin and buy one from someone who knows what they're doing!

    stop worrying about your solder! as long as its jointed ok, dont worry!!
    most solder these days has flux in it, in the old days you had to dip your solder in the flux to stop a 'dry joint' so it doesnt crack off, plummers and gas fitters use flux.
    solder will not affect sound quality, anyone who says it does is crackers.

    Looks like a decent job to me, especially for a first time. The most important things are that the joint is strong enough for you mechanically, the joint is sound and that you havn't short-circuited anything (easily tested with a multimeter which is definitely a worthwhile investment if you don't already have one).

    I actually use that cable for my sub lead and think it works very well. :)

    I'm getting clever now...

    How many people have wanted to feed 2 subwoofers from a single subwoofer output?
    How many people end up using a nasty 'splitter'?

    Well, check my new handywork out, with this 3 metre 'split' subwoofer lead!
    My soldering on this baby is much better, and I've reinforced each connection with insulation tape on the inside.

    I don't need it, but you never know... I might end up with 2 SVS subwoofers someday.

    Hi Jules, for a first attempt you've done pretty well. :thumbsup:
    I've seen worse done by so called professionals :rolleyes:

    What temperature is your soldering iron? Your joints look like they could have done with a bit more heat to get the solder to flow more. It takes a bit of practice to get the joint hot enough without melting the dielectric or sleeve.

    Make sure the flux contained in the solder is non corrosive as some solder uses acid which will destroy the joint over time if not cleaned off. It is good practice to clean off any flux residue anyway, as it looks better. IPA is the best joint cleaner for flux cored solder.


    Cheers, Mylo
