Chops first official box design?

[porkchop 304]

I think I got my first box design down, hope to have you guys double check it all for me.......

tunning will be at 35 hz.

port area is 62 sqaure inches

box volume is 4.29 ( havn't figured out what the 45's and braceing will displace)

I just used 4 cubes for all my math.

useing 3/4" mdf and will use double baffle.

port opening will measure 15.5" W X 4" H , useing the bottom of the enclosure as the bottom of the port, ported to the side.

port length will be 27.5" long

the port will fire toward a vertical mdf wall on the drivers side.

sub will fire up, and i will plan on having it inverted, for now.

it will work out that the sub will be almost centered in the vehicle.

keeping in mind this is not a comp build so the pressure i would put on the mic is not factored in.

the sub will be the furthest away from the internal port opening.

43.5" W X 17"D X 16"H

i think that is all the info needed,

planning on useing the 1 5/8" coarse drywall screws, predrilling and countersinking all holes/

useing wood glue and clamps, gotta look up prefered name brand of glue still.

will either caulk with normal caulk or look into useing more of the same used on first box, high velocity duct sealant < this sh*t is tuff stuff now!

planning on useing internal braceing and 45's, leaning toward 2" X 4" 's for braceing material due to cost, even though i like the look of the all thread better.

will round over all angles and sand box down,

the finish will start out naked due to low funds, slowly becoming all black.

everything will be blacked out in the rear, it will either be black or chrome.....with white strobes, (slow)

well looking for any and all input as usuall,

so let me know what you think newbies,

and gurus please check my math!

thanks guys,

chop

equipment is in sig!

I like it chop. Although it will end up being 4 cubes overall. When I originally drew it all out it was 4. IDK if the 4.29 was before your bracing and 45's or not, but I was just stating.

Who's building it? You going to come to jordans and do it?

[shizzzon 461]

You've got some wrong calculations here.

I start off with 5.37cubes GROSS.

Using a port that is 15.5" x 4" 27.5" physical length is a 33hz tone, not 35hz.

also, even if you stuck with that, the physical length would actually be 26.75" attached behind side wall = ~29.5" acoustically because this is a slot port which will extend the port length.

Displacement for such port leaves you with 4.23 cubes + sub displacement + bracing to account for so you will be will into the 3.8 range by then.

[mikey5472 16]

Sub is inverted. I believe.

[porkchop 304]

well i guess no one is building it, i can't seem to get it right yet........

i will pm shizzzon and ask him to get me back in line......

and then go from there.

[mikey5472 16]

Mk...

[shizzzon 461]

oh crap.. u are right.. i completely forgot about him saying that.

Well, i wouldnt dog someone over 0.06 cuft off but the tuning i might...

[porkchop 304]

so, if we shorten the port length up then the rest is alright, correct?

thank chop

[porkchop 304]

i am king of crappy cell phone pics!!!

had rattlebox317 help me gut the rear of the truck out and ran the welding cable......

the sound deadening and subfloor will be up real soon.

hoping to have any last points of input on the enclosure design real soon.

plan on begining the box as soon as perhaps tomorrow.

got the screws and glue.

bought the peel and seal, expanding foam, and counter sink / drill bits.

getting mdf tomorrow.

will be switching this over to a build log soon....

wanting to confirm our design formula, seems that there is a differance but don't know where?

oh and the job status is still zero, been doing alot of skimping to keep the audio scene going.

mikey, 5 + hours there? makes a long day..... i better see if i got a hook up on a room for the weekend... down there enough , i should have....
