I'm not sure the 35 would like it. Just doesn't strike me as a phase-box kinda sub if you know what I mean.

Go ported with 1 6" aero IMO :)

honestly i dont know what you mean.... :blush: haha

Isn't this just your average ported box? I thought T lines were elaborate.

they can be... this was teh first one i made...

assuming that your box is for one sub... you may not need to double baffle... i noticed that Tlines have lower port velocity then regular ported boxes... jus brace it alil...i used 3/4 in mahogany ply on my Tline. and it doesnt flex at all.

8th wave tlines sound interesting... it looks good... so lets see some build pics.. lol

My first truck... My first Real build...

Everybody wants their system to be....

1. Cheap

2. Reliable

3. Loud

...you can only pick two.

I think he means sounds interesting, as in the concept sounds interesting, not that they sound interesting.

My System:

Pioneer AVH-P3200BT

4-Dayton 7 inch reference series (front doors)

8-Onkyo 3/4 inch tweeters (dash)

1-Sundown Audio 100.4D (mids/highs)

2-18" BTL's (for now)

Crescendo 3kwp (for sale)

Complete rebuild coming soon...

did a bit of testing on my t-line in my room. (made of pvc very easy to mess with)

i brought it down to about half the length which would be 45 hz 8th wave (its normally 45 hz quarter wave)

awful. absolutely awful

output on the low end is pathetic. but boy throw a 90 hz tone on it.... bleeding ears

that could be sub related

I have one in my room for at 8" dayton that is around a 33hz 1/8 wave.

Its really musical and drops really low. I think a saw somewhere that forevrbumpn said if the qms is below 7 it does well on dropping below the 1/4 wave and can get to the 1/8 wave. Ill have to look up the specs on the dayton to see if they are like that.

that said.. i guess i already put an 1/8 wave box in my car, since did have that 8" 1/8 wave in my car for a few weeks.

maybe i can get some quick spl results from that box sometime soon.

Edit: the qms on my Dayton sub is 3.08, so that could explain why mine did better on the 1/8 wave. what sub are you testing with?

heres the specs of my sub

*VCdia: 1-1/4"

*Impedance: 4 ohms

*Re: 3.6 ohms

*Frequency range: 45-1,500 Hz

*Fs: 45 Hz

*SPL: 82 dB 2.83V/1m

*Vas: .24 cu.ft.

*Qms: 2.68

*Qes: .61

*Qts: .49

*Xmax 9.25mm

i think the qts is too high. your right tho it probably is the sub. the difference was amazing tho between quarter and eigth.

why does my little sub sound like ass in an 8th wave?

well lemme rephrase that, sounds like ass in comparison to the quarter wave.

I have a ritual called "terminator". I crouch in the shower in the "naked terminator" pose. With eyes closed I crouch for a minute and visualize either Arnie or the guy from the 2nd movie. I then start to hum the T2 theme. Slowly I rise to a standing position and open my eyes. It helps me get through my day. The only problem is if the shower curtain sticks to my terminator leg. It sorta ruins the fantasy.
