Si Mag Broke!!!?????

[tcguy85 10+ year member]

can you see the actual coil? i'm not familiar with the mag so i don't know if you can... but if you can look at it.

the leads look burnt.

Second side tinsel leads look discolored... sounds like an open coil if the woofer isn't moving and the amp isn't going into protect.

glad i wasnt the only one who caught that //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

my guess lies with george on this one. death by a clipped amp.

or as a second guess, i might venture as far as to say its something on the HU that went out, albeit that might be way off, but possible.

As a heads up... the 1500D can exceed it's 1500 watt rating. If you do the math that is around 2200 watts or so with battery voltage dipping as low as 11.5 volts. It wasn't adjusted for distortion, but still sounds fine on an actual bass track rather than tones -- at least I wasn't able to hear much added distortion over the insanely loud bass coming from the test setup

What you see is my test bench... 50 amp Pyramid power supply, Kinetik 2400, Duralast 1000CA battery, 2x SI Mags all in parallel @ 0.6 ohms measured DCR at the end of the speaker wire. Fluke AC current meter used for output voltage and current, Sears DMM used to show power supply voltage. Calculated impedance rise of 1.08 ohms @ 55 Hz.

So... careful with those gains and that volume control //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

so you're saying it's from to much power not clipping?

Same thing, really. Clipping just creates more power as a square wave (clipping) has more area under the curve at a given amplitude than a sine wave.

i know clipping results in to much power, but i mean you're saying he killed it with to much clean power?

Could be, could be clipping. Either way, too much power seems to have been delivered to the speaker -- whether it was clipped or "clean" doesn't really matter, too much power is too much power. I do know that the 1500D is capable of exceeding the limits of the Mag, gotta be careful when setting them up -- the combo works great when the amp is set to match the limits of the sub, I've used the combo myself and loved it.

sundown is such a hack.

2200w, when you specifically ordered 1500 pshhh...

i dont know what the freak hppened its werd indead

that was my friend, sorry

im still reading what you guys said...

I, for one, would feel incredibly ripped off if I purchased what I thought was a 1.5kW amplifier and instead got one capable of making over 2kW //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

Nice amps you're building there, sundownz //content.invisioncic.com/y282845/emoticons/thumbsup.gif.3287b36ca96645a13a43aff531f37f02.gif

If my needs ever exceed my current monoblock (that I'm only using to half potential currently) I may very well look at your gear next. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

i think im just gonna like give away my mag on the forums...or maybe get a re cone..because im gonna end up getting the 3ed gen mags.

two of em!

 

[IgnoreMe 5,000+ posts]

you wanna know something?

i got a old claw 12" mag that needs a recone. so right now its useless...and guess what? its my freakin baby and i cant bring myself to get rid of it! even my 2nd gen 15" mag is sitting in my exploder right now and i wanted to go more spl but i cant bring myself to sell that one either. its just a beautiful sub, and ill know as soon as i sell it ill want to kick myself in the nuts.

oh yea, btw the mag you got now and the newer version are suppose to be almost identical. i dont see a point in selling your sub cheap just to shell out more for a brand new one. you can spend less, and get one used off ca.com and be in the same boat, but with more money in your pocket at the end of the day. i say recone + another 15" used. my .02c

You cant figure out shit till you get a DMM, but you can speculate all you want.
