2012 Frame / Cone -- First Built Woofer


Recommended Posts

I did get a little too happy with it last night when I first fired it up -- you'll hear a small metallic sound because of some slight damage I did to it then (woops!). Either way I was still able to get a good test out of it for this video and show it in action -- with more testing to come as we get more prototypes together. The good news is I'll be able to make it even tougher on production thanks to my mistake =)

I woke up, put on some coffee, and say to myself, "i wonder if that video of the new sundowns is up yet". I log on to the forums and, bam! Awesome man. Looks great!

I am kicking myself a bit for getting crazy last night with it, haha... what I did was push it hard enough to exit the coil completely from the gap by a large amount -- the 12" frame supports 50mm of one-way travel not counting frame thickness... 59mm with frame thickness... and 71mm with vent spacer thickness added -- minus 8mm for triple joint ring so we can go 63mm one-way before bottoming the ring... and we have 62.5mm in the motor... so I had it up around 60mm one-way (which is actually 5mm PAST surround linearity)... which makes the coil about 1/2" past the gap *laughs*

So when it came back down it knicked the top plate and knocked loose 1/2 of one voice coil (the coil is an 8-layer bifilar which is wound as a quad; so you can knock out 1/2 of a coil by breaking one wire) and this wire is rubbing on the top plate now making that metallic sound (I can see the loose wire through the vent spacer -- WOOPS!!!).

Either way I have some ideas to minimize that possibility; although, I must admit, I was being totally careless with it to do that!

Needless to say it was pretty crazy and just me being too happy with my new toy :)

Thank you for the in depth description on the noise! Everything looks great, love the 4" peak to peak. Now try not to kill it too soon.

I still want your 12" surround for my sub....just sayin!
