FI Q in a Phase Box.

i like how they used people who doesn't know anything about car audio in their videos. I always thought their vids were corny.

your not the only that thinks that way...//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Remember the days when people though it was impossible for ported boxes to be louder than sealed? They swore by it.

Remember when CRX boxes revolutionized the SPL scene in street Class? What about bandpass vehicles?

Even though you guys don't think so, I believe Alan Dante made a believer our of everybody with his number. Hence revolutionizing the SPL industry.

If you think you can build it...then go for it. And especially if you think you can do a loud number with it on the meter...definitely go for it...and I hope to see your works in the lanes.

Good luck.

Yet another reply with out data. I KNOW you've had to of put this 6.5" on the TL.

If not it makes me wonder...

Look at it this way: What he is doing isnt much different from what companies that do acoustic tests on aircrafts are doing except on a smaller scale. He uses one small woofer in an efficent one not wonder acoustic design to obtain high SPL's in a small STRONGLY braced container. If his car is all cement it is a bank vault, not a car.

What are they doing? Large mechanical tranducers in extremely efficent designs in LARGE bank vaults.

The difference...they can change frequincy and their bank vault isnt mobile.

As far as the challenge. Not everyone has the money and time to buy a vehcile and completely destroy it to put up a number at a competition.

Oh and I wasnt aware ported and CRX boxes where patented...

Take me to jail now if they are because I've sold both. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

If you've already applied for the patent the why not release the information. Once you've applied you can tell everyone because if they take the info and apply as well you applied first and if you dont receive the patent then anyone can reverse engineer one of your boxes and sell them as well. Adire Audio released the principals of XBL^2 once they applied for the patent...I consider XBL^2 a bigger step than some Magic box.

I dont think you can patent a simple t-line enclosure //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif

Good luck tuan with your endeavor, the thing about trying to sell boxes to people online is folks on here are usually pretty educated and when you claim things beyond normal enclosure capabilities you're going to get scrutiny. There have been too many other people already that have spoiled the scene with so called "wonderboxes", such as Tcab and powered4sound. So its forever going to be tough to rival past that. And IMO a box is just a box...its up to you to put the effort into the install way before the box makes the setup louder. /rant

Remember when you told me

1cm makes all the difference in the world

... and then I said this ....

What dream are you living in? As stated above, you have not revolutionized the acoustic model here .. you are simply playing with well-known equations to get your box modeled right.
Please ... lets see for 30Hz .... wavelength = ~11.43m ... so 1/4 = 2.858m ... so 90degrees of phase change over 2.85m .. lets see 1cm = 0.315degrees off ... oh my god! the sky is falling

Ok .... for what driver ... what frequency range are you attenuating ... I chose a 30Hz "tune" for it ... sure .. it can be made significantly smaller for a higher tune, but I wasn't doing that ... I just grabbed a random number and gave blackmax his box sizing. Please, do prove me wrong....don't just tell me I am

jim

You have yet to disprove or refute this in any way. Please answer the questions about this ... as you have apparently already applied for a patent, therefore need not worry about sharing your information, since you have the legally documented prior art if anyone attempts to "steal" this.

Concrete Volvo

You of all people know the benefit of this .... its just like building a strong enclosure ... the stronger the pressure chamber ... the higher the SPL ... nothing revolutionary there ... just taking box AND car building to the extreme.

Good post. I agree.

Basically what everyone's been saying. Stop trying to spread hype with people we have no background knowledge of and never seen before in our lives.

You would much better to promote you product with real data.

Also the challenge of "can you build a better" box can be issued if there is real data (i.e. TL data).

C'mon Tuan how hard is it to put a TL in your car...you ARE a DB Drag world champ...I would think you carry a TL with you wherever you go...

alan's car is like 90% concrete and was meant for doing little else but make tones....i mean come on, its a volvo with a concrete roof, floor and most of the interior is raw. Thats not revolitionary, thats borerline illegal in competition.

this thread reminds me of powered4sound, anyone else remember those turkey's ?

lol yea u right about that

p4s = pos

How is this any different than a TL?
Is the designer here just calling it by a new name ... and playin' the patent-hype game to sell it?

The compression chamber changes the response a lot, model it as a back loaded horn with a straight "horn" instead of a TL and you'll see the difference.

I'll post an example in a sec.

 

[Volenti 10+ year member]

Top response is a back loaded "horn" with no flare and a compression chamber.

Bottom response is the "horn" only (really a TL)

As you can see you get a significant extension in lower bass response with the compression chamber, so there's no snake oil involved there, however there's no mystery there either...

It's funny how so many of you criticize us of try to patent something. Do you seriously think that we would release any kind of information or pictures prior to an attempt to a patent?

Yes, there are some patents that we're looking at. None of which include an enclosure mensioned above. In addition, there is another patent on a woofer design that we're also working with. Of course, we wouldn't be foolish enough to release any info so that it can be copied or criticized until after it's complete.

You want to see numbers? Then bring it in the lanes...where numbers count.

Numbers on the meter doesn't show much. Especially with transient response. Like I said over and over again...the vast majority of our customers aren't basehead. Rather they're enthusiasts whom seek extremely great sound quality with low end extension and still retain decent output.

It's pretty funny. Last year...I was challenged by many box builders. They claim that we can build decent boxes...but nowhere to be loud on the meter. And in october of 2006...the result was a World Finals win for us. If you think it's easy to win World finals...then I challenge anybody to do a decent number and win...no excuses such as (don't have time, too expensive, etc). Now again, we're challenged in other area's yet many people still want to see numbers. Honestly guys, numbers on the meter doesn't really mean squat.

I'm not posting to promote anything or prove anything. Our team builds excellent boxes that sounds incredible. In some designs we use some formula's that have yet to be sent in text books. All the money for our designs and enclosure builds...goes directly into our team fundings for the website, host competitions, etc and not for personal gains like other parties out there. We contribute a good amount of information to the car audio industry.

It's sad to see many unsupportive members in the car audio industry...where new ideas are always shot down by people whom think they know it all and those who do not appreciate the accomplishments of others.

I know ... I came back shortly after that and stated it was a volume coupled/compression chamber/etc tl/labrynth/phase box/etc.

Best of luck in the lanes then my friend ... I was hoping we could have a good technical chat here ... either way, I respect what you do and have done ... I just wanted to learn/share and educate more of them members here (including myself) as to the inner workings of some of these designs.
