i would love to see a pix of that i have yet to see more than a single lead attached at the coil.
ur work always looks great just wondering the benifits when the lead wire is so much larger than the coil wire itself how much dose it help.

Look at that coil, its 16ga! //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif It will handle gobs of amperage.

Me too! 10kw burps should sound nice!

so my dual lead recone is now obsolete... i want a refund //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

i have seen subs with single leads handle 20k for burps. wondering if there is a improvement in dbs with more lead wire,hmmm. curious. anybody know?

i would venture to say it's more of a daily driving option. tinsel breakage is related to subs abused over long periods of time (at least for me). for high-power burps, i'd say mechanical failure ie: spiders ripping, formers flying through dust caps ect are more common issues.

i could be wrong. i know the leads on the former that connect the coils to the tinsels are extremely small. i would think that would be a bottle neck...

That's correct to an extent.

I have seen a lot of leadwire burning from high powered burps, as well as just being yanked apart when they are set up with different styles of leads. Things like smashing the leads inbetween the spiders, free flloating them, etc can also cause undue stress, friction and heat to be applied to the leads.

Being sewn down reduces the movement of the lead itself. Just keeping them from flopping all around, smacking into the cone and spiders makes a world of difference. In most cases, up to twice the power handling from the start vs free floating leads when using the same size and amount of leadwire.

When they are smashed inbetween the spiders, friction is a killer. Heat builds up, burns the spider, etc. Not to mention that when placed inbetween the spiders, the leads are not allowed enough length to stretch under high excursion, causing them to be completely ripped in half!

This way also causes non-linearity in the spipder itself. No matter what anyone says, a bunch of wire smashed inbetween the spiders has a big effect on the suspension.

As for the coil to lead connection, you have to remember that this happens in a region of the speaker that does not move. This connection is made and then glued in place. The coil itself is more or less a hunk of material. It moves as a whole, but the small individual strands make up and entire unit. If the actual strand of wire was under stress from movement, friction, etc, then sure.

The leads are under high amounts of stress at all times during play, therefore they need to be a lot more resistant to these conditions.

i got ya dave.

with alum coils do you solder or wrap and glue?

Dave has a good idea here... you would be amazed how many people can burn up a HEAVY lead with just an SAZ-1500D wired to 1/2 ohm daily.

The leads I use on my Nightshade will take 10-20k on a burp... but I've had customers burn them in two on a single 1500D before, no joke.

I am going to start offering doubled up leads for this reason.
