Default The OFFICIAL "Snail Shell" Thread!!!

http://www.powered4sound.com/media.html

download the last video there... anyone believe it??

am I the only one that noticed that the bass output generated by two 15's causes everything to viabrate, meaning you couldn't even get a clear video of the people in the car?



even if the box was 105dB efficient, which is quite possible for a FULL SIZE HORN, you're still not going to have enough cone excursion on a 6.5inch woofer to reproduce 30Hz at the same output as a pair of 15's would do it...

Meh, it's just a TL, I've just finished making one for a customer to suit 2 12'' that wouldn't model nicely in a typical design (vented, bandpass ect) It'll go in monday hopefully, I'll let you know how it performs compared to standard enclosures.

I have built many sub enclosures including John Nolte's snail shell. I will say that this enclosure is very loud. A well designed ported enclosure would be just as loud but would have a narrower passband. They work but they arn't the end all be all of sub enclosures.

so, do we call ******** to the video on that site? or do you believe it?

whats so special about these boxes? they won't even SELL me the plans for one. I'm not going to pay postage on a pile of wood. If I bought one, there's nothing stopping me from cutting it in half and making my own.. so, why won't they sell the plans?

Sorry if I didn't make it clear. These enclosures are loud and I do not doubt the videos. Remember though that those videos are made using very powerful amps, high quality subs, and most likely upgrade charging systems.

I was refering to the two 6.5inch woofers sounding like 15inch subs video....

What I dont understand is how they use the same sized enclosure for two 6.5" speakers as they would for for a 12". Something doesnt seem right

Pardon? lol

each snail shell is supposidly specifically designed for the woofer. I don't imagine even a full, "proper" horn would make a 6.5inch woofer sound like a 15inch sub though, let alone something that looks like a too short transmission line stuck on the end of a too short horn. :P
