RL-i 8 TL box design

[Aaron Clinton 2,372]

Hotcarl was kind enough to send me a design someone had made up for him for a SS RL-i 8. I wanted to see if you guys could take a look at it for me and see what you think. I personally have never designed or built a TL. Not to mention I will not have time to build this any time soon, so don't ask for progress pictures

it doesn't fit under my seat

[Acidburn 10]

doesnt quite look right to me, but i dont know that much about TL's

maybe i'll throw one together this fall

[Adrian_D 520]

hmmm, you could use a straight line and not have to deal with angles. there are diffrences but i don't know much about tls. check the decware forum. there is a pretty good discussion on tls on the ht forum. and a lot of smart guys.

maybe they can help with a design.

just looking at it kinda reminds me of nolte's snailshell.

i might build this and drop my rl-i8 into it...put it in the boy's room....

or the TB....

yeah, i think i will do this...

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

i wanted a low end beast, so i extended the length of the line and increased the mouth to 5".

it is fun though.

If someone makes it and really likes it i'll make one as well.

For now its just sealed with a 10" PR

is it just me or does it look like a rather simple TL design...?

[Eldorado 0]

nope, it looks pretty cookie cuttter

[Adrian_D 520]

i want to trymy rl-i10 in a tl , but i don't have too much time for research and building.

[mrray13 30]

is it just me or does it look like a rather simple TL design...?

which is exactly why i want to build this one..lol..

and will this weekend...

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

[DevilDriver 28]

most TL's used for bass will be fairly simple, because there is less need for a choke or any stuffing in them.

i believe mountaineerman over at caraudio.com does a lot of TL's and everyone has had success with his designs.

I believe this is sourced from him.

[joebangaa 0]

if it turns out nice, i think i'm gonna have to roll out to the boonies and make one at elias'

[mrray13 30]

i built it, i built it..yes i did, i built it!!

anyway..i get a pic or two, and a vid...

going to test it h2h against the sealed enclosure (.17ft^3) in the room and then throw a meter on it in car...see what it does against a 12" hehe

anyone want the leftovers??

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

[mrray13 30]

testing to commence in a few hours...

wooowhooo!!

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

[mrray13 30]

ok...just got done in room..

source unit is a jvc hx-z1 delivering 110 watts of power to the subwoofer via a seperate subwoofer output (rated 120 x 2 for the highs, 55 x 2 for the subs) that's regulated for anywhere from 6-16 ohm...teh rl-i is wired for 8...

both enclosures will be placed facing the wall, 4" away. the mic is 6' away, about 1' below the sub.

first up is the recommended .17ft^3 sealed endeavor. and i'll tell ya, the rl-i performs in this thing. blends nicely with the rest of the system (7" dayton alum mids, hifi 1" textile dome tweeters,using memphis mclass xovers, in .66ft^3 tuned to 55hz IIRC, i'll have to look that up around here.) and delivers awesome bass response. it peaked at 104.5db@ ~ 50hz, not bad for 110watts.

the transmission line, well, wow. at 32-35hz this thing delivers around 110db. talk about lowend reenforcement..lol... and averages around 106-108 for the rest of the range i played it.but it also blends better with the rest of the system then the sealed one did. i believe it's because the selaed one is overpowered a bit by the fact the highs are getting 240 watts compared to it's 110. the tl keeps up and even mnakes the tweeters appear to be not as bright. again, i think this is due to the power level.

next up...

the rl-i8 in tl vs the la strike in basic ported in the tb!!

the la will have a power advantage, i'll be using an orion 2500d and the la is wired for 4 ohms. the rl-i for 8.....

and off we go!!!!

pics later...

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

[mrray13 30]

part one of in car testing done!! and i've gotta say, so far so great!

first test was the lightning audio strike x2 12" in 2.5ft^3 tuned to 28hz. the best i could do with this set up (again, orion 2500d wired at 4 ohms) was a 130.5 @ 45hz, every try was legal, mic on dash, truck off, sealed up car. (if you remember, same box, same amp and same power as it was ~ 4ohm as well, the rl-s sub, did a 136.6 @ 34hz). musiclly, this sub does a good job in this application. no real complaints here.

second test...removed the la and box, dropped in the rl-i and the tl, same settings on everything, except it's wired tp the orion at 8 ohm and it breaks out a 128.7@ 41hz! half the power, and half the cone area and it damn near equals the LA! at a lower frequency! tweak the amp a bit, and boom, 129.9 @ 42hz! play it outlaw for giggles..132.7@41hz!

so i know the tl is loud (we already knew the rl-i was capable..lol) for what power it's getting. now it's time for music! i'll report back on this one as it'll stay in the tb for a couple of days......

again, factory electrical system, factory headunit, all scores legal save the one noted, on a tl.

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

Hrmmm....

Why must you make me build this !!!!

Do you have a simple ported enclosure for it to see how much louder/quieter the TL is

i might actually sell this one..hence why it's not carpeted..lol..

but no, i don't have a simple ported box. but i think one is definitely in the future. like you, i have to know what the difference is...

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
