drew that up today. its all drawn to scale. 1mm = 2 inches

specs

outside dim

33" W x 17.5" L x 14" H

port is 100 sq inches

8" W x 12.5" H x 53" L

8th wave "tuned" to 32 hz

it isnt much larger than my current box and could be very feasible to do. question is... is it worth it? how good are 8th waves? how will the DD handle it? Foreverbumpn i hope you see this

oh and what kind of power should i put on it? i know it should be half rms but i mean... it is a DD after all...

dont forget the 1/4 wave of the box will out do the 1/8th wave, so poly fill should be used

but as long as you have a cabin gain close to the 1/8th wave you may be alright

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.

the poly fill will lower the gain of the 1/4 wave, and increase the gain of the 1/8th wave

the pollyfill helps trick the box and make it think its bigger right?

i see. cant say i ever messed with that.

hrm.

im concerned with how much output itll have and how much itll play. right now i have some bad drop offs around 30 and 55 hz in my current box. anything in the 20's is almost gone and anything above 60 is being taken care of by the speakers... sucky

plus i do not have a lot of time or money to invest into something im not sure will work right. but hye thats half the fun isnt it? haha

and in tlines it slows down the sound wave, so it seems like a longer line too.

Dang it. I thought i was gonna be the first one to put an 8th wave tline in a car on here.

you still will be no worries. im kinda slow on things like this. i take a lot of time researching and just as long building
