Xcon 10 4th order

[shortfuze9 0]

Has anyone tried a xcon in a 4th order? I have 1 10 right now on a saz1500@ .5 in a 1.75^3ft tuned to 31hz with 31" port area. It's in a 18 wheeler and am having trouble getting it as loud as I'm sure it's capable of. I previously tried a 1.25 sealed and enclosures didn't make much of a difference. This vehicle previously had a difficult time due to cancellation. The space I have to work with is 13.5h, 37w, 23d. I was gonna try using a smaller enclosure and less port, maybe down to 13" per cube. I'm about to order a second 10 and another 1500 to get the cone area and power up. But I wanted to eliminate the canceling of the cone/port and try a 4th order with the port firing into the cabin. I don't have much experience with 4th orders though an was looking for help in the design. I love the sound of the xcons, even with the cancel it's getting, it blends perfectly with my 3 way active front stage. Any ideas?

There are a handful of members on here that are experienced with 4th orders. I personally have not used our Xcon 10 in a 4th order, so I cannot speak directly from experience. A second one, like you mentioned with more power, should easily see a very noticeable output increase.

Thanks Aaron. What do think about the idea of going from 17" port per cube in a 1.75 cu ft and going down to 13" port area per cube in a 1.45 cu ft enclosure? Would that control the cone a little better?

13"^2 is very small for a 1.45 box. 17" should be pretty close to good for the 1.75.

Not 13" total port. It would be about 19^2in. Didn't Marks first dual 18 xcon box have about 13-14" of port per cube?

Lose the idea of port area per cube. For the XCON 10 I would use a minimum of 20^2 in... Ideally I would use 25 to 30 per 10.

I'm just a hair over 30" of port area now with the 1.75 box. Sounds good, blends well, but it seems like its trying to unload when I turn it up to around 85%. Amp was set with dd-1 so there's no clipping or anything. To me it just feels like this enclosure doesn't have enough cone control.

What is your ssf set at? What music do you notice this happening with?

[shortfuze9 0]

It's set around 25hz, maybe a bit higher. The bottoming out happens mostly on rap, when it dips a little lower. Jeezy, Lil Jon, bass mekanik, Kanye. On rock it's near perfect, no bottoming out, but I would like some more output. I will be ordering a 2nd 10, but I'd like to the enclosure figured out first. My next one was going to be 1.45, port is 11.5x1.75, 30" long.

Do you have some over all specs on the new enclosure? Beyond just measurements?

[shortfuze9 0]

Like? This one is right at 1.75^3ft net after sub and port dis. Port is 11.5x2 5/8, 40" long, tuning is around 30hz.

New one I've been working in is 1.45^3ft net after port and sub dis. Tuned to 31ish. This is per sub. The overall enclosure is 34w, 21d, 13h. Sub on either side of a 3.5" port that splits at a 45 in the back.

What are you using to find your tunning. What calculator ect.

The12volt.com

Then usually I compare the results I get there with the Torres calc. Occasionally BP6.

I'm confused. Yours is in a 4th order.

[///M5 2,833]

And yes, I was serious....but I do realize you are referring to a BP enclosure. That being said, I am sure that is not the right solution for you. To get a 4th order BP louder than a standard 4th order you'll seriously butcher the frequency response. And most likely instead you'll end up with something that isn't louder but has steep roll offs in the listening range at both ends.

What do you suggest he should do sean?

[Sencheezy 689]

OP, would it be possible for you to upload pictures of your install? I would love to see that big RIG! haha, I've always wondered if anybody has put systems in those things But also the main concern would to see how your enclosure is unloading. Picture would help the best to give us in idea of the environment your enclosure is in.

I will try later. I've been doing all this from my phone and haven't been able to log in thru the IP Mobile app. There are many big trucks with systems in them. I've always had one in mine. Usually I don't have a problem getting it right, but then again usually I use the top bunk for my enclosure which gives the roof and the rest of the sleeper to load off of. I had to get rid of the top bunk to fit a 32" LCD tv in here so I only have a 38x14x23in crawl space under the bed to work with. Enclosure fires straight out into the cab. Thinking about my issue some, makes me think it's doing what it should, but there is zero cabin gain this way. I've tried many subs and enclosures in here with no luck. Tried a dd3512 on 1500 watts in a folded horn. Sounded good but didn't get loud. Then went to 2 dd3512's on a saz3500 in a 3^3ft with a 6" aero tuned to 35 subs front, port to the side. Now I'm with the xcon. First was 1.25 sealed. Now the 1.75 ported. Sub and port forward. This is only barely noticeably louder.

The reason for asking for the 4th order, was that I feel like the cone and port are offsetting each other. A BP would eliminate the front wave and take cancellation out of the picture.

here's what I've got for pics. I didn't take too many while building cause I don't have any kind of dust collection and I didn't want my camera getting dusty.

[Aaron Clinton 2,372]

Looks great in it's new home.

[ricksi30 923]

The new enclosure looks great man.

[shortfuze9 0]

that's the one that I'm not so happy with. It sounds good, but in the cab it's not loud. In the sleeper, it's loud as can be. I'll just try adding another sub and amp, and hope for the best I guess. Here's the design of the new one. it's a little less port area and volume, hopefully gonna try to get it to load a little more.
