L7 12" Blew - Whats the deal?

[spoonman 10+ year member]

OK guys...I took my L7 to an authorized dealer and had it sent back to Kicker for warranty.

I want to make sure I set it up correctly next time. My amp is a Rockford Fosgate Type RF X6. It does not have a subsonic filter on it. Instead, it has an "infrasonic filter" toggle switch and a phase toggle switch that can either be set at 0 or 180. How should I configure this?

If you're running your subwoofers in a ported enclosure, you'll want to set the subsonic filter 1/2 an octave below the tuning frequency (So if the enclosure is tuned to 40 Hz, divide 40 by 2 to get 20, then divide 20 by 2 and add that to itself to get 30 (20/2 = 10 ... 10 + 20 = 30) ... //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

i can reconize the smell of a burning VC from a mile away, happend to me many times,

you cant move your sub cause the voice coil has came apart in the motor, kinda like a slinky but worse, you should next time be sure the "loud" function is off on your cd player (helps blow things up) and it would be less train on everything if you tuned you cd player gains higher and you amp gains lower, having it 3/4 way up is really high, especally if you want to still be able to hear your mids and highs, have the gain up 75% can make one notch on your volume knob be way to much, (VOLUME 25-26 for example) the gain is to be used to match up the volume level so your amp volume increases steadily with the cd player, have it up like that could be like this, once your cd players volume level has reached %25 of its volume capability, your amp is tryin to do 100%,

i hope this helps in some way, if not its bumped

not entirely accurate but i'm sure someone has explained to you the "gain" situation by now...

Just for fun I turned my amp gains way up to like 70 percent and was careful with my hu volume, just to see what it was like. The sound quality did seem to suffer a bit, no noticable volume difference, but it did seem to be straining more. Could have just been psycho-acoustics though.

normal voice coil = o

blown voice coil = O

and it jams up in the VC gap causing it to not move

im gettin my brand new 12 l7 soon //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

nice ported box @ 32 hz and im hoping it'll get loud and last long

wasnt going to go for an l7, but $120 shipped to canada for a brand new 2004 l7 is too good to pass up.
