do L7's usually have a lot of xmax? my L7's move pretty good and ive broken a tinsel lead already once, but i thought there were suppose to be a more stiff moving sub.

Well, the Xmax isn't shabby. If you are snapping tinsel leads, then you are likely exceeding the Xmax. Stiff or not, given the right circumstances it isn't difficult to push a sub beyond what it was designed to do.

im not even pushing a full 750 watts to it, and my gain is weigh down, maybe im just not used to a sub with pretty good xmax

Xmax is what 15-16mm on the 12L7?

if you are breaking tinsel leads then you are significantly exceeding not only the maximum linear travel, but also the maximum safe mechanical travel as well.

Keep the excursion down a bit, unless you want another damaged L7.

Not being used to it is no excuse for breaking a tinsel lead during normal usage. That is very rare, especially when it is being underpowered.

Are you running a relatively high tuned ported enclosure with no subsonic filter? Unloading the subs below tuning will exceed its excursion limits pretty easy.

17mm I believe.

Well what size/type of box do you have it in?

mine move quite a bit, but I havent had a problem w/tinsel leads breaking

but I have had the spider seperate in the middle. also make sure you have a ssf with ported boxes

I have a pair of L7's in a subzone ported box. 600W each from PPI PC 2600's with a SSF. No problems with mine in the year and a half I have had them

i just snapped one tinsel lead and that was like 2 weeks ago its been running good ever since, could it just have been a one time problem?

The Xmax of an S12L7 is 13 mm ...

Which isn't a whole heck of a lot //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

yea i was thinking it wasnt suppose to be alot of xmax, i mean its not comparable to vids of like XXX's and Brahmas ive seen that are coming like out past the surround it just looks like its going good. i'll try and get a vid of the xmax tonight/tommorow and post it up and see what u guys think.

With the square corners, I doubt those surrounds could allow for extreme excursion.

 

[jtomsic 5,000+ posts]

i just wasnt expecting as much excursion as im getting, thet things are really loud definately live up to their reputation.
