Is there another possible fold for this monster? Perhaps with one dimension of 7' or 7'6"?

It can definitely be refolded. But, you have to find someone willing to do it. It is not a trivial process in most cases.

I am willing to try, i just need to understand what I'm doing first. It seems to me that all you really need is a spreadsheet that shows the length of each section of a given slope. All of these different segments of different slopes added up give you the total length of the horn. Is this correct or am i missing something? Does a table like this exist somewhere?

I've got the drivers but unless I can find someone to pick up my subs, it looks like it will be 2 weeks frown.gif I'm busy this weekend and the woodworking place is 1 1/2 hours away. I'm hoping my friends who is getting the other 2 can pick up all 4!

Sucks that you have to wait another two weeks! So mach five has your UXL-18's ready? Mark told me I was top of the list, but I haven't heard anything mad.gif. Sounds like Canadian favoritism tongue.gif My truck is at the mechanics, so I don't have an easy way to pickup the plywood anyway...

N8 used different cones. We are still waiting until he gets cones for ours.

Ah, good to know. Either way I'll be a few weeks before I have everything ready anyway. Luke sure has set the bar pretty high with the quality of his work.

He has done great! Really helped me out with my build looking at his pictures.

Ya I had the baskets and motors already. I used different cones. We had to do some surgery to get the cones on some blown drivers but it worked out great. If you bought hw many drivers I do, I'm sure you'd get a bit of favoritism! plus the 15 minute drive makes life pretty easy biggrin.gif

You guys always make the Hatch cover so easy to do. Fits like a glove.

Looks like I'll have the side panels on tomorrow and then they're ready for Duratex!. Unfortunately, Monday I leave for CA for the week and won't be also to start that last step until next weekend...so close!

Freaking outstanding Luke!

Figured I would post these here too for any of you building these cabs.


Here are the basic response flattening EQ settings for the G horn and Othorn (REW and mini-dsp format). I recommend using these first and then EQing for the room response. They allow both cabs to be crossed over at 100-120Hz or even 150Hz for the Othorn. I recommend a 100-120Hz low pass for the Othorn and 55-80Hz for the G horn (50-60Hz is best but it can be used up to 100hz with the EQ if needed).



Also for the Othorn you want a 18dB/Octave Butterworth high pass filter at 23-24Hz.



For the G horn you want a 18dB/Octave Butterworth high pass filter at 13 or 14Hz if you will be really cranking on it with HT bass.

Quick question.

Will the XXX work with the GH?

Ricci had said the XXX is very much unsuitable in a horn.

Figures...Thanks.

For some reason I was under the impression that any of the "more capable" subs would be a good match.

Soooo...how does it sound?

Here were the questions I had going in:


1. On any non-sealed sub I've ever had, port noise has ALWAYS ended with me selling it and going back to sealed. Would the GH have port noise/turbulence?

2. Can one of these really outperform my quad 5400's with 16,000+ watts of power?

3. Would the beefed up bracing help with the cabinet resonances?

4. Can this design really handle 4,000+ watts of power?


Sooo...


1. ZERO port noise or turbulence, and I hit 117db at 15hz at the LP before my ears cried uncle. I also had the mains powered off, so all I could hear was the sub

2. Yes, one of these actually does outperform quad 5400's down low, and dare I say, it sounds better!

3. I heard nothing bad from the cabinet using Ricci's basic EQ settings. However, I put a 60hz filter on it to limit the upper frequencies.

4. Yes, yes it can.


I can't wait to get the second one up and running!biggrin.gif
post #449 of 758
I can't wait to see the graphs!
I wonder if you could set them on the side and use it as a coffee table.
How much vibration is there in the panels when played at 117db?

Get some videos if you can. It's always fun watching your vids. It's even funner showing them to people who aren't into HT. biggrin.gif

How much does one Gjallarhorn weigh all complete?

You do know the sealed fan boy club (basically the entire AVS DIY section) is going to tear you to shreds, right? biggrin.gif

The measurements on data bass seem to indicate that from 15-30Hz its actually pretty evenly matched vs quad LMS.

Could you elaborate on how it outperforms it?

I'm not opposing your opinion by the way, just curious on why you think its better.
