home, was making two.
finished one about 6 months ago, the other is just sitting there is pieces still, oh well.

they werent the prettiest designs, but they sounded the best...

got any pics of the finished enclosure?

was that enclosure designed by you or did you use plans from some one ealse?

it looks interesting and i bet the bass is deep. what driver did you use?

not bad,

but the sub selection was not the best for a horn loaded. i think i would of gone with a lower QTS and FS for a horn.

no, the woofer suits the horn quite well... (in theory) and in practice, the horn actually has a flatter response than I even expected.

thats cool. i wouldnt have expected it from a sub with such high QTS, Qes and Fs.

but i guess design is everything and frequency responce down to 30hz with that sub seems about right and is not bad at all.

i personaly prefer TL enclosures, smaller enclosure compared to a horn loaded and better sounding and you can always fine tune with polyfill.

i might experiment with horn loading in the future. once i get the TL enclosure design down.

The first sentence made sense, but the second one didnt. See what under my username? You designed this box for my old jetta.http://img.photobucket.com/albums/v387/willabong8/IMG_9806.jpg
I left you positive feedback... just because you dont remember it doesnt mean you have be such an ******* about it...

It was back when you were lemans...

Ohhh sorry about the attitude //content.invisioncic.com/y282845/emoticons/redface.gif.62fdbfe1a101588a808c4cff71bcb942.gif

did you use the same pioneer sub in this one as in your last one?

the last one seems to have a longer horn and smaller sealed chamber, with more folds before it hits the last part of the horn.so its posible that your last one got tuned a bit lower.

also by practice i have noticed that puting more folds on a port or horn or tl slows down the air being pushed even more, making the tuning frequency even lower then whats calculated. so if you calculate for a strait horn, port or TL and then fold it 5 to 6 times changing its direction 180* per fold it lowers the tuning to a lower tuning because the air has to slow down every time it hits and U turn. wich is good when building a horn loaded or TL since they tend to be so big because of the Horn or TL lenght, it allows you to make a smaller enclosure then calculated and still get the low end bass you look for, and if you need it to go lower it never hurts to add some polyfill to lower the tuning even more.

nice box by the way.

"edited: from 90* to 180*"

 

[PowerNaudio 10+ year member]

im sorry on the post above yours i meant 180* not 90*.

its interesting to see the same calculations of an enclosure, be build in two diffrent forms and get two diffrent results in sound comparison.

i guess the extra folds on the second enclosure you build did change the tuning some.

what ealse could have cause the second one to sound better then the other? did you use any polyfill on one off them?

 

[PowerNaudio 10+ year member]

i guess so. horn loading was never meant to be folded anyways so yeah by having a large part of the horn in a strait direction would actualy help the sound quality.

was there any change in loudnes or did it stayed the same?
