    however, there's a guy with an ib setup on a f/b page ive been following that cut out and baffled his rear floor pan rendering his car a large enclosure, but the work took quite a bit calculation according to him, and i tend to believe it with this video demo https://www.youtube.com/watch?v=NLsvAVM_vxA
    phase not group delay is usually the biggest issue with vented alignments. its funny how most woofers actually phase response free air *****..

    I remember long ago i can't recall who did some group delay testing and it was said that at 40 hz 20ms was very hard to hear and at 30hz 30 ms was very hard to hear but there is no mistaking the phase shift in FR..

    very good, joel. alot of factors need to be considered to get the phase delay of a reflex alignment to be linear when referencing the input signal as 0* phase. until we have constant linear phase filtering/processing specific to a dynamic array of sonic reproduction applications that can infinitely adjust every fraction of frequency in real time, we're still relegated to arduous trial and error of making physical changes to get transients 'perfectly' (which i use very loosely) aligned across the entire spectrum.

    bring on the 'transfer function' jokes.



    i think im gonna go sit on the toilet and take a big papermaker where it belongs.

    i have a SLICK *** way of lineaizing alot of that phase shift and increasing transient response at the same time. i keep telling these fools its easy and the best way to do it.
    wiggas be on that bandaid shit..

    Why don't you just take out a business loan and get behind your product(s) 100% instead of trying to get other people to help foot the bill. That way you can own the success or failure of your ideas. Judging by what you've said about your yearly salary it shouldn't be too much of an issue to get a bank to back you or even be self funded.

    Unfortunately it doesn't look like you're going to get anywhere trying to hawk your ideas for someone else to help finance as I'm sure most people are worried about being catfished.

    I swear some diyma ppl are fking idiots. Thinking a high dollar amp will magically make their sub setup become SQ and completely ignore everything else thats actually relevant to how a good sub stage is done.

    In that guy's defense, it doesn't look like English is his first language and it may be he doesn't even understand what you wrote. As likely he really believes or wants to believe that he is going to hear some subtle nuances <80hz if he spends enough money.
