ZCON 12D2 in 3 cubes @31Hz Enclosure, port question

[kj4jaq 5]

it is a toyota tundra double cab... the port would be pointing under the front passenger seat

what he said.  But I have a better sketch to go off of now, will try to have a prototype drawn up by tonight.

 

I thought it would be cool to utilize the space between the rails- as it worked out to supply almost exactly the port area needed.

That truck is going to be loud!!!!!!!!!

good, i am tired if playing small ball, i want to play big ball!  i'm ready to have some fun with my music...i hope to have some sort of flex because my last 2 subs were not able to provide me with much...

Eric- that sketch you sent me- the 25x22.5x13top / 18bottom...that is sitting on top the rails?

ALSO- is the 18" at the bottom all I can use between the rails?

yeah the trap box plans with 18" bottom depth was sitting on the rails...the furthest the port using the 6x13 3/4 diameter space between the rails could go is 24"...will be tricky trying to get it in the truck if we go any larger...

 

just know that the plans i sent was for 3.6 cubes after sub displacement only..it didn't include the port area, 3.25 ft3 is the max optimal volume for ported box for the zcon 12

to your dimensions...~2.95Ft^3  after displacements....tuned to 33hz...31hz required too much port length-  11.5x4.5x40" of port as it is.

looks good Lee, great job, how much more port length wouldve been required to hit 31hz?  I was thinking possibly making a sliding port that goes over the permanent to be able to adjust the freq further...i just run in to issues getting it in the truck at that length, once it is in the truck that is a different story

according to winisd, you need 46.5" of port for 31,  40.5" for 33.  I doubt you'll audibly notice the difference.

[kj4jaq 5]

well, i guess you are right.  I guess I wouldn't be able to notice the difference..guess it is time to find someone to build it.  You know me, I am no carpenter like you.  Will send the plans to DC Customs for a quote.

[Lee Carter 150]

man I was so tired last night- I screwed up the sketch up back....though the math was right....redone the whole theng....and still made the top 3/4 too deep....it is 13.75 deep on the top.

 

you have 9 to 10" of available woofer depth- think I read the 12's are ~8" deep.

sending the sketchup file to your company email.

[kj4jaq 5]

got it, thanks again, i owe you a 6 pack of your favorite  beverages

Wouldn't too hard to assemble.

 

Here's the Cut List:

 

2- 23 7/8 x 21 (baffles)

 

2- 23.5 x 18b/13t (sides)

 

1- 28 3/4 x 22 1/2 (back)

 

1- 22.5 x 13 (top)

 

1- 22.5 x 24 (bottom)

 

2- 16 1/2 x 4 1/2 (inner port sides)

 

1- 16 1/2 x 13 (inner port front)

 

2- 24 x 4 1/2 (lower port sides)

 

1- 24 x 13 (lower port bottom)

Add where to find the center of the woofer cut out.

Also that cut list doesn't take into account the angles of the baffle

That SK-1500 amp used to power that zcon. lol

yeah, but he has the amp, it will be now powered of rf1500bdcp, birth sheet shows 1800+ watts at 1ohm at 14.4, so i figure 1650ish at 13.8/14

That should be plenty to get it moving!

sketchup kicks butt.....~10.3* pitch

looking forward to my new baby being born, W140, work your magic!

[kj4jaq 5]

this wait is lethal, the sub travels with me in the truck, looking for his home

[Lee Carter 150]

^^It's true.LOL  Surprised he doesn't tote it on his person in a holster.

[kj4jaq 5]

box is shipped, can't wait!
