Finally coming together

What movie source did you use for the video?

@fuzz092888 these graphs are of the dual opposed UXL? I wonder if you simply need feet to plant that sub firmly...

You have a consistent dip across all of those crossovers, with the lowest being 40 hz moving the dip further down. I'll bet thats a mechanical loss due to enclosure movement!

 

[fuzz092888]

None, that's the CEA burst at 15Hz.

Nope, that's the system all 4 subs. Feet wouldn't do anything to stop cabinet movement. It's a flat bottom with a couple hundred pounds on top, how would decreasing surface area contact make it more firm? If anything it'd probably snap the feet off

Has nothing to do with cabinet movement, just a room modes that change due to what frequencies the 12" woofers in the speakers come into play. Subs aren't placed perfectly enough to get a completely flat FR combined with speakers. I had thought about moving the subs around, but immediately discarded that idea when I remembered how heavy they are. I'll just cross at 150Hz. K.I.S.S. as they say

 

[TheWarrior]

Was the mic at the LP? Then yes repositioning will solve that. Standing waves suck!

 

[TheWarrior]

Not necessarily the UXL but move something closer to the LP

 

[fuzz092888]

Well this is larger than I expected



With a little 4.5" driver sitting on the dust cap



Next to the UXL. Fell a little bit as I took the pic, but you can definitely see how much larger this is. I kinda wish it had the same cone as the UXL though.

I want to see the reaction of your GF.

She took it better than expected. Especially since I had to tell her there was another one coming.

And that you can't afford a ring for at least another six months

C'mon man, you can't be just putting that out there like that. What if she sees? WHAT IF SHE SEES?!?!?!?!?!?!?

If there was a Richard move button I would give it to you...........think about it.

Just doing my civic duty

 

[TheWarrior]

He's just gotta test to see how much she's willing to put up with! Make SURE she's the right one, otherwise kiss your speakers good bye!

It's all in the thread title ...

Do you guys remember that Cheech and Chong skit, eff me Alex?

Ralph and Herbie???

Got my shipping notice for the second of the FTW's.

Also, Mark from Mach 5 just started a FB page. Turns out he can make a 32" sub and is prototyping a 24" driver as well. Color me curious.

 

[TheWarrior]

But don't you also still need that 4 foot high spoiler on your car!?

Think how slow the bass will be though. What you need is a pair DO towers with 16x8" drivers per sub.

True, but if that's the case, why not 126x4" drivers? I mean, the bass will be so fast I probably won't even hear it because the sound waves will be moving so quickly.
