The Old Power 4 Sound Guys eh..

I liked the old vids

"The 6.5" That sounds like a 15"

The hair video & the roof flex..

Snail Shell Search it on ECA.. lol

I've been rocking a folded horn for 2 years now.

Devildriver, if you don't think you can properly load a horn in a vehicle, you need to understand the effects of the vehicle on the horn design itself, and then you can design those into the horn, and take advantage of them, which in fact, make the horn small enough to load.

Good theory from you, but bad in practical application. It can be done easily, if you don't believe me, come sit in my 2 door trunk car with a folded horn with a pair of 10's hitting 150's, and then tell me I'm wrong.

Actually, they have some horn and 1/4 wave qualities that they use to their advantage //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

But just because the port is long enough doesn't make it a snail shell.On page two, looks like a ported box with just a large port.

To the austrailian dude, you're waaaaaaay off.Don't be made because you couldn't get one loud in your mom's 30 year old station wagon.

If properly designed, they can have a good advantage over ported boxes in output and sound quality.Now that I own a TL I intend on doing some tests and vids.

In all reality though, most of it was overhyped, but it's still a decent enclosure if done properly.

The port is long and large enough for the 1/4 wave effects in the port it's self to effect the response (the port resonates like in a pipe organ, in addition to, but in a different way from how it resonates with the enclosure tuning), the result is significantly different from a box of the same net volume with the same tuning but using smaller, shorter (normal) ports.

Really good try, but still not quite a snail shell. Getting a little warmer.

yeah, not crap enough to be a snail shell. //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

its already been proven, that "snailshells" aren't as loud as folded horns, so, whats the point in this thread?

unless ofcourse, we're talking in a sedan, in which case, a transmission line would be better than a horn anyway.

also, the snailshells are a half assed attempt at a transmission line... flares, different width "port" area, it makes no difference, its still a transmission line, and it still wont make two 6.5inch woofers sound like two 15inch subs... lol

Anyone remember the rule about horns increasing distortion???

what folded horn are you running?

i have some odd little excel workbook at home.//content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif

You got a problem with people that drive station wagons?

No offense, but you're one of the few people in here that apparently knows why a SS is special... care to share?

no he doesn't, he's a n00b

Been reading too many Hexibase posts lately?

I especially liked this part:

"you need to understand the effects of the vehicle on the horn design itself"

I couldn't agree more! By knowing the effects of the vehicle on the horn design, I realize that achieving any acoustic gain at typical sub frequencies is pretty well impossible.

A horn, by definition, must provide acoustic gain by converting high pressure/low velocity waves at the cone of the driver into low pressure/high velocity waves at the mouth of the horn. This simply cannot be done in a vehicle at low frequencies. Many are foolish and mistake the natural effects of cabin gain for acoustic gain provided by the horn. What most have done is taken a ported box, made it look like a horn, lowered turbulence at the termination point in the port, achieved more directivity and experienced cabin gain. Again, to be a horn, it must provide acoustic gain, which I challenge you to achieve below 50-60hz.

In which case, good luck making a horn in a vehicle.

6 inch driver in a van. That would be interesting. Somebody do it.

They built his in fact...or designed it and he built it....but horns in general are pretty interesting...not that i understand them but i try:crying:
