Exactly as I suspected, the m1u was too much for one of the 7 year old Crossfires haha.  It delaminated the cone, just like the first one.  Luckily, it wasn't as severe as the first one, so I was able to cobble it back together with a mess of CA glue.  Just for fun, before I got to that point, I metered it with just the 3 subs (and a plug blocking the 4th hole).  

3 12s on the m1u at .5:

154.6dB legal at 27hz

156.2dB driver window down at 30hz

Now that I have the broken sub sketchily put back together, I went and gave it a listen yesterday.  It magically held up to some abuse.  I'm gonna throw it on the meter again this weekend, but I doubt it'll last long.  

I have my eyes on another Crossfire 4k and 4 of Crossfire's new XT3 12s.  Maybe that's the combo I need to see a 160 door open on the dash in this thing ;)

What kinda amp is the M1U? I'm not familiar.

Here's a slight update:

After I shredded that sub when I threw the M1U in for testing, I was miraculously able to glue it back together in multiple pieces.  After I got all 4 subs playing again, I re-metered it:

155.79dB legal at 27hz

158.68dB outlaw at 36hz

 

I'm definitely at the limits of these woofers mechanically.  I purchased my second CF 4k and will be throwing it in the next few days.  They will be strapped at .7ohm a piece on the current subs, and .5 per when I rebuild these XSv1s with TI baskets and XT3 recones.

 

I'm also going to try some box mods, like extending my rear ports and bringing tuning down to 27hz.  I also need to make a PVC roundover for the port block I made for the front chamber.  I just purchased an SSA meter, so I can do some serious testing and tuning.

Also, fun fact, this thing is loud as shit on the driver's side headrest with both doors open.  I put the meter on the driver headrest both doors open, and it did a 158.8 at 42hz on ONE 4k.

Also, I got a port plug so I can plug one rear port and drop rear tuning to 19hz (after I extend them).  I'm trying to see what I can pull out of this thing for Subsonic Suicide.  

This thing will be at the Sundown show August 17th if anyone wants a demo :)

I have a TON of footage from Sundown show.  Maybe I'll make a little edit and upload it to the tuuuube.  I'll post it up in here if I do.  

 

I'm not gonna make the Sky High BBQ because it's literally on the exact opposite side of the country.  I wish I could.

 

Equipment updates:

Right now, I'm running 4 of the new Crossfire C7v3 12s on two Crossfire XS-4ks.  She's putting up mid 158s at 33hz (tuning is still lowered) and mid 157s at 28hz.  153s at 20hz.  Legal, it's doing mid 156s at 50hz and 27hz.
