While i eagerly await some Ethos let me bring you up to speed.

shipping containers for a workshop? -
adding the extra lead will do several things. 1. add about 3 grams to the moving mass of the driver. will shift parameters, almost unnoticeable on something this large even on Klippel. parameters shift anyway and are an average set over testing. 2.) could induce slap but HIGHLY unlikely to be audible. They are sewn pretty good. 3) could induce distortion by shifting spider parameters. But this is a non issue in the substage as suspension distortion is considered non audible. And one you get over 140 db you have to get into 40 and 50 percent over all distortion before it become audible. Off the top of my head that's all I can think of now.

If it is just the lead at that much power then this will fix that. And if the coil itself is fine on 30 second runs this is VERY helpful for competitors. This means I can stay with the 4 layer coil instead of an 8. This means that numbers wise the driver would be louder on the same amount if power up high due to inductance. As when you double coil wire length you can expect inductance to drop upper DB 's around 3 DB. We would still of course need to tighten the spider pack to keep it with mechanical limits to keep the coil from rocking. The coil itself will NEVER bottom out as the spider will hit the top plate first.

I'm interested if the joint failed or the lead itself fail. That amount of power is getting close to the max rating of the lead so it's possible just the lead let go. However it is very common for larger coils to fail at the solder joint where the lead meats the coil. I assume it's because the wire at that point is encased in ca glue and can't dissipate heat like the rest of the coil.

I moved my folders around in photobucket. I guess the URL changed. -
I will be branching out during 2014. NO I AM NOT LEAVING SSA. What other forums, venues, specific car shows, what have you, would you like DDS to show peesense. Give me a listing.

Best brand of welding wire or is it all the same?
Quentin Jarrell replied to DedicatedEnthusiast's topic in Amplifiers / Head Units / Processors / Electrical
Yep they use a cotton lining between the copper and jacket. Remember. Welders are using this stuff to weld over several hundred feet. It needs something to help flex at that length. -
oh, they'll fit. I got a reciprocating saw that says they will

upgrading from a 12 to a 15 or 18 on 1200 watts? opinions needed!
Quentin Jarrell replied to gsWes's topic in Subwoofers / Speakers
that would be the cheapest option unles you sold your current sub -

Below is 2/0 EB Flex. The discoloration is mold. It has been sitting under a covered car port for about 6 months. -

I've used welding supply and the EB stuff. Yes the EB has less strand cound but both contain he same surface area therefore both within spec standards. The EB flex however is a good bit cheaper. I have found that the EB wire does not have any micro ban additive in the rubber to keep mold from growing on the jacket if that would be a problem -

Save time and money and but the EB flex -
For those of you that want a driver specifically designed for fourth order bandpass enclosures I am looking at offering this option. As long as I don't have to add mass to the moving assembly to achieve desirable frequency response it will be a free of charge option. Details later today.
-
It's at Pat's office right now. I already know what the parameters will be as I already had samples tested a year ago. I'm just really anal and like to triple check my work. The box will be small. For a bandpass you can expect an s factor of .7 with a total volume of around 2.5 cft. Going down to 1.5 cft will get you in the realm of a .5 s factor. Pass band will be ~30-75 hz while keeping ripple under 3 db
