fane 18" folded horn tt-1000

I did measurements pointing the speaker upwards outside, this way theres no obstacles in the way

Please post your results. Maybe in the measuring subwoofers thread?

Making the measurements this way will give you some interference with the reflected wave from the ground. Unless you dug a hole for the speaker to make the mouth level with the ground?
Also note that any objects close to the speaker will still affect the measurement, even though they are not in "the line of sight" of the speaker.

Yes you're Right about that, this technique is probably better for directional highmid that omnidirectional bass, which is actually what i used it for. For bass it's probably better to put a bin on the ground in a field making it halfspace?

Yes I completely agree

hello, iv been looking for bass cab plans to match the 4x bottom bass cab in my profile pic, mine where built by some else some time about 2002ish, they look just like fane tt1000 but they are smaller, they are w580, h580, d750, i will double check but im sure thats there size, i saw some else mention maybe a slimed down version, do anyone have any plans that are modified, thanks for any help
