2 18" in an explorer sport

[I want SExxx 10+ year member]

just calculate it as two seperate boxes..... but make sure to only include 1/2 of the wood displacement......... like instead of taking 1.5 off of your measurement for internal volume only take .75

so for example, using the one from RE i posted, to calculate the notch area, i would just calculate a sealed box essentially and add the volume to the ported box i calculated?

wouldn't that change the tuning, etc?

dont use that thing...... just calculate your box volume and then plug it into a port length calculator.

ok.

hey i got something i was given to try from another member here. do you have any experience in t-line style boxes or anything besides a standard ported?

i have a design that is for 2 18's. the box has a long *** side firing port and what seems to be only ~4 cubes of internal space. now i know it sounds crazy but this member used this box and then afterwards built another box that was your standard ported box that was 15 cubes and after 1 day of using it he said he took that box out and went back to the t-line style box. he says it had more output and had a very flat response compared to the standard ported box he tried.

let me know if you interested in seeing the plans, as id rather do it through PM since i dont just wanna hand this guys shit out like that.

Transmission lines are great BUT...... I have a lot of experience with them and there is really no sure way to design them...... its more of a well I know my line needs to be around about this long and I need to taper it X much and blah blah and then you finish and it sounds okay and doesn't get real loud, but you change the subs that are in it and then it slams.......... Like for example I built a T-line for some audiobahns it slammed I mean just pounded and down low too....... but when we tried to put some w3v2s in there thy sounded like poop..... but the w3s pwned the bahns in a regular ported box......... its just weird....... his design probably wouldn't be optimal or you subs and honestly T-lines may peak a tad louder and flatten the sound but to me I like he sound of a big low tuned ported box better. T-Lines don't have the low end bias of a large ported box tuned to say 32hz. I lik a 35ish hx peak and a gradual drop off as you rise in frequency. NOT TO MENTION that this is your first big build...... a T-line is a little to much for you to take on I think.................. but if you wanna give it a try I'll whip ya something up, but no guarantees..... I'd say just stick to 12 cubes @ 32hz ported.

Edit: PM me the design and I'll let ya know what I think.

well this guy own 2 18" BL's which is why he offered me the design. i dont even know what a t-line is, its just from the research i did about the company that it might be a t-line hybrid or something of the sort. at first i dismissed the plans from the guy because i told him it was just a regular ported box that fired sideways, and the guy said thats exactly what he thought it was until he built it and put it in his jeep suv.

pming you now, but like i said, im not sure if its a t-line or a ported box or anything really.

honestly......... the designer of that box....... not going to mention any names ..... is very good..... BUT I very seriously doubt that box has a whole lot of low-end...... looks more like a get loud box. If you really want to try a T-line Ill design you one better suited for your vehicle, but my vote is to still just go ported.

yeah..prolly will lack low end ALOT..being that the box is only 10.5cf //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif i got the same design from the guy..

hence the reason i wasnt just gonna post it up in this thread. but as far as actual box capabilities heres what the guy told me....

he said that no matter what he did with the other standard ported box (17 cubes) it would not:

a) play lower

b) play louder

i asked him what hes tried and he said firing the box and port back helped his lowend with the 17 cuber, but it still wasnt as deep as the smaller box.

as far as trying a t-line, its not that i wanna try it real bad. its moreso the fact of what the other member told me and it sparked my curiosity. i told myself, well he probably just hasnt heard a properly ported box in which case he pointed me to his build thread (did you check it out?) and it kinda sparked my interest, that this member had the exact same doubts as me and when he built it he was surprised in what he was hearing.

heres a few things from the pm that he wrote

- "like i said, i put the xxxx right back in. louder, more musical, which ultimately leads to the ultimate lows the xxxx pumps out."

- "anyway, good luck and lemme know if you ever use one of those designs.

 

i know they are way funky designs for two 18"s, trust me, i know this. dumbest box i ever thought about building for them. but man does it work. you would laugh if you sat in my car knowing how small that box is..."

- " i didnt ask for a specific tuning.

 

i told him i wanted it to play any kind of music i put in my cd player, he told me it was tuned to low 30s, it sounds like it.

 

i dont completely understand the design either but you dont have to even consider it."

- and finally ""hmm exactly the opposite of what i thought would happen. weird."

 

and his: it did improve, but what i meant is nothing i could do would make it even par with the other box.

 

the xxxx is like under 70 square inches, lol!

 

the other box is 160.

 

the xxxx has a very flat response, it acts like a sealed box but gets fukin LOUD!"

whoops one more from his build thread:

-"both boxes are ported, this was mainly an update to show a few pics to someone... smile.gif

 

big box is 17cuft gross tuned to 34hz.

 

little box is xxxx designed by xxx, its tuned low 30s.

 

i had the big box in for 1 day and put the t-box back in.

 

xxx ftw..."

actually if you look at it in a standard side firing ported box...it 10.5 gross and roughly 4 cubes after displacement. thats what caught me off guard.

did you see his build thread on sound solutions audio?

That's not how a t-line works..... esentially here is no box volume. It's just a port X feet long that should get smaller and smaller as it goes.

get the 2 18s...im telling you your going to regret it if you dont, or atleast 4 12s or somthing big

i know a guy with 4 15" memphis mojos in a regular explorer and 2 18s in explorer sport, no reason you cant get 2 18s in there

well, i just took the leap and picked up 2 18" BL's tonight //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif . any chance you got a link or info on the guy with 2 18's in an explorer sport?

i want sexxx : so in that case that box doesnt sound like a t-line at all. the port seems like its the same all the way around by the looks of it, which would make it a ported box no? or am i missing something?

i remember when i had my first gen mag it sat in a box that was tuned super low and required a similar style port going front to back though, instead of side to side but of course the port was equally spaced through out the box.

Hmm....2 18's in a Explorer Sport.....hmm I gots enough room in my Tahoe for 2 of those.....

derrick is running some 18's in a tahoe, if you need ideas. hes got some pics in this thread
