XCon Box Specs

[shizzzon 461]

I dont know if i'm askin this too early but since they are available now, what is the box requirements for all XCONs?

Also, what is recommended tuning?

[johnecon2001 82]

A tad larger than the recommended box size for the ICON's. And tune around 30-34hz. The sweet spot on the ICON's is at 31hz.

The Icons hit like a sledge hemmer at 28hz

[shizzzon 461]

hmm, getting interesting.

I'm really interested in the 18s. ICONs do not come in 18s so this is all the possible boxes i have chosen for them-

13.2 cubes NET tuned to 35hz Port area= 158sqin

13.0 cubes NET tuned to 34hz Port area= 158sqin

12.8 cubes NET tuned to 33hz Port area= 158sqin

13.0 cubes NET tuned to 32hz Port area= 144sqin

13.0 cubes NET tuned to 31hz Port area= 138sqin

13.0 cubes NET tuned to 30hz Port area= 131sqin

Are any of these box sizes optimal or recommended for 2 Xcon 18s?

I know that 2 Icon 10"'s tuned at 35 hz moved enough air to do a hair trick... I would say 33hz for a daily driver. But I dont know haw many cubes

[shizzzon 461]

well i already do a 146.8 @34hz with just 2 12s and 4,400w of power, i'm hoping i can break a 150 at a low frequency with these babies if my volume is large enough.

If you keep the box BIG you should be able to. SSA has definitely done lots of things right. I'd say they are one of the best subs on the market if not the best. I am dieing to hear the Xcons. The Dcons sounded way better than I ever expected so the Xcons should be unreal......... I cant wait for Thumpper to get is system done..... I wonder if he'll split the cost of some hearing ads for me after he defines me lol

This one seem's good.

Iv'e got a pair of xcon 18's sitting in my room now, just waiting for an amp

Im gonna try to get 13cubes @ 30Hz.

[shizzzon 461]

Sweet man!

When u think u gonna have yours done and ready to listen to?

I'm aimin around june or july to be done as long as I get my other gear sold.

The box I'm using is gonna be sub and port forward. Any excess volume around the front baffle will be sealed off to try and get as little volume to pressurize as possible.

Port flowing in between 2 front seats, 26.25" high x 5" wide according to ur recommendation.

I'll be running 2 2200w amps on mine

[RobClay 20]

Im hoping before the summer ends.

But there's no telling.

Im debating on either a sundown3500D or an aq3500D.

Your running the 2200's right?

[Thumpper 266]

I'll be running side by side common chambers with 7.0cf3 each

side plus displacement with my 15's....

talking about a FLAT RESPONSE WOW!!!!!

[shizzzon 461]

Hmm, that may not be good for me.

If it takes 7 cubes per 15 just to get flat, then it definitely sounds like the 18s need way more because I don't want my ported box peakin 10hz+ above tuning because my volume is too low.

I think you read it wrong

that is 7 cubes ( common chamber ) for a PAIR of 15"................( 3.50cf3 for each 15" )

[Thumpper 266]

here is the Xcon 18" ( SINGLE WOOFER )

[johnecon2001 82]

I believe Mark's box is right at the 20 cube spot for his 2 18's.

[Thumpper 266]

here is a graph for a pair of 18" Xcons with 20 cubes...

LMAO......talking about FLAT

WOW. Nice looking graph! Too bad it probably won't look like that in car...haha

[ABXX49 20]

What program is that?

[shizzzon 461]

Could you explain to me what exactly the Transfer function magnitude tells us?

normally, the designs i have done for myself, the graph is always peaking well above 0db right after tuning.

The current build i have- 2 AQ HDC3 12s in a 3.8cuft box @38hz-

graph goes to +1db peak at 39hz but suddenly rolls off to -3 at 59hz.

graph shows -3 below tuning at 34.5hz.

The overall listening experience between 30-60hz sounds fantastic. Anything higher than 60hz is pretty weak. Anything below 30hz is almost inaudible.

So, with that given, what does Transfer function magnitude tell me and everyone else?

[shizzzon 461]

here is what i got-

Explain to me what this means if i choose to go with 1 of these 2 designs-

13.0 cubes NET tuned to 36hz -

13.0 cubes NET tuned to 30hz -

[Aaron Clinton 2,372]

We will have the Xcon page updated soon. The 1st of those last two graphs will yield a sizable bump in output, or peak around what looks to be the 46/47hz area. The second graph with the slightly lower tuning still has the same frequency peak, but much less pronounced. If you want a more ground-pounder type of install the 1st would be the choice, or a flatter more daily type would be the second. Are you able to go a little larger in displacement? Also where is your LPF set at? If you don't have the room to go larger and don't mind the peak, the 18's will seriously get it done, but if you can't go larger and want a very flat response like Trevor illustrated above, maybe consider the 15's.

[shizzzon 461]

ok, thanks. It all makes sense now, hehe.

These are some very interesting subwoofers.

[JASON123 1]

What program is that?

It look's like Term-PAK Enclosure Design but not sure

Yep it's Term-Pak..

The same graphing I got slammed on

in another thread for posting..
