the snail shells are crap. P4S is a shonky business that is on its way down the drain. The 6.5inch video is fake, and this talk isn't at all detrimental to their sales... 😛 lol
Its only one idiot from a place noone gives a damn about, with nothing better to do.......cant bring down P4S. I doubt they are worried about you LOL
What's so impressive? That box is just a non driver optimised mass loaded TL.
Nothing to see here folks, move along now...

Of all the threads on all the forums concerned with P4S or SS or the 6.5's the vast majority of posts disbelieve.
Having wasted a while looking back over some SS threads I came across some good quotes on what the boxes are.....
"Q. Dual Bass Reflex?A more effecient ABC box, correct or no? A. Bingo."
"LIKE I SAID, ITS EXACTLY LIKE A 6TH ORDER SERIES-TUNED BANDPASS"
!No. they act like a 6th order bandpass with the woofer on the outside. they act alot like ABC boxes!
OK. have a small 1st chamber, this restricts higher freqs (it is ported around 40-50 hz)
Next chamber, moderate volume, tuned low with a huge port that should* be long.
last chamber, smaller volume, but not as small as the 1st. and ported around 40-50 hz.
* calculate all ports as the same size, and subtract the length of the high tuned port from the length of the low tuned port. now find what the low tuned chamber would be tuned to with that size port, and make it somewhat smaller.
........Or how about a deffinative quote from the designer........
"Some might be inclined to assume this to be a transmission line enclosure, but this box has some unique aspects. The box servo tunes the Fb of the first chamber, thus the ratio of exit area to port taper controls the woofer throughout the range of tuning as the Fb follows the resonant F3 tuning point. Thus calling it a Dual Coupled Servo-Phasing Transoctave Sliding Resonance Enclosure."
.......excellent! There it is then all cleared up as to why these boxes are so good........

lol, this guy should audition to be the engineering officier in the next Star Trek series, he already has the technobabble down pat.

yeah... that was the definition he gave me when I asked. It was something very similar anyway, I think it changes every time 😀
and your the one who replied after i told people to let it die,so its your faultSkinnyBoy said:

but you're the one who replied to my reply.. so its YOUR FAULT!!!
An externally hosted image should be here but it was not working when we last tested it.
I don't have time to read this whole thread, but I have to say, what is the point of using a 6 1/2" woofer in such a huge TL enclosure when you could probably fit a really good 12 or 15 in a box that size.
They must think it's giving them "fast" bass cause the driver is so small.

honestly, it sounded better, and possibly even louder in a BIGGER car... hmm but good none the less..
I guess I will need to bring my friend in here to show a nice waterfall FR plot of this video...
well peeps (thats you) theres another video on the P4S multimedia page, I'm just downloading it now 🙂

its of the 6.5inch snailshells, so, we get to have another laugh at them 😀
86, 87, 88, 89, 90%
nearly done 😀
97%
98%
99%
100%!!!!
YAY!!!
hmm... now I believe it even less... 😛
you get e better look at the size of the boxes...
WOW!!! an empty maccas cup viabrating on the roof.... =\
I'm convinced... is his two 6.5's sound like a 15inch sub, then my single 12inch in a horn sounds like two 18's 😛

I hate to repeate myself but the 6.5" boxes arnt SS boxes. You can even tell this by looking at the boxes.

well, that, my fury little friend, is very much besides the point, because even two 8inch woofers in a full horn, 4 times the size of those boxes isn't going to sound like two 15inch subs...
