Second order is when you blow the first pair ,6th order they decide for you that just not your game and block your #. Bear with me it's 4am lol

😂😂😂

awesome, it's funny to see how just recently companies have started making 6th order PA subs, true innovation starts with people

Well if your subs are as powerful as your electric bikes then I've gotta hear a video of that with a good mic.

@@Dakoustics Bose have been using 6th order for years.

Acoustimass had like a 4th order firing into a 6h order lol #Bose

Thomas Jester Tarulli of team orion has/had a (6) 15" sub system in a 6th order that is very high output with a wide frequency response. It's quite legendary his performance. His set up is 1:1 and tuned at 25 and 50hz. As always it seems it's about trial and error as each car/home is so different.

Yeah, car audio is a popular target for thieves. The 6th in my trunk would likely but a thiefs back out, and the amps are under it. Kind of bitter sweet, half the reason I'm into audio is because of the 15" sub my brother gave me, which was the only audio component from his car which wasn't taken.

@@Dakoustics Yeah, there were certainly more than one of them when they hit my cousin's car. You would have to be one of those world's strongest man types to make off with a large, awkwardly shaped object weighing roughly 150 lbs on your own. :) He actually found out who it was through the grapevine on his college campus, and there were three of them if I remember correctly. Couldn't prove it unfortunately though.

How did your build turn out? If it’s monstrous I’ll put the same in my civic.

@@Ichabod_Jericho I scrapped it and went a massive audio 12. It can handle more power and hit way harder deeper bass. Sold that W6.

adaboy4z I knew it! Part of me wants to go JL, part of me knew big brand names have cheaped out

@@Ichabod_Jericho Don't get me wrong that JL W6 is a beast on 600 watts but there are better subs for cheaper and can handle more power. I already had a Kicker KXA800.1 amp and a Kicker KX1200.1 so it was natural to use that power!!!

Bandpass subs are known to be bad because of bad designs and lack of understanding from the user. Check out the "STM S118 SUB" it is a pro audio bandpass sub intended for most demanding concerts and festivals. When bandpass subs are designed by professionals and used by engineers, bandpass designs are very powerful and accurate desings.

6th best

Will never go back

@@robertkurtz7587 From a 4th or 6th?

Glad I could be of service, enjoy!

@@Dakoustics for designing a 4th or 6th for my Morel Ultimo SC 122. I'd like mainly 16-20 hz tune. Thanks brother, very informative video.

BASSN SANE I always tell people that the vids do not do justice to the sound. But I do have a few pictures on Facebook of it.

Id love to hear that design

That makes a very inefficient enclosure for reproducing lows that anybody would consider loud...... I did the basic math on it assuming you used .1-.2 of a cube, with your suggested port length the tuning would be entirely too high to effectively play 10hz without sounding like a wet fart and unloading the sub so "I will take things that didnt happen for $600, Alex"

@@zacharyhafer2806 With all due respect, if the enclosure was so bad I would not make it in the first place; in fact it’s my favorite enclosure for playing infrasonics which is what it’s mainly designed for. “I will educate those who have no experience for $1000 Alex”. Here’s a video. ukposts.info/have/v-deo/hpWEd2Z6aIhn1Zc.html

I like the idea of a 5th order, so front of the driver is in a transmission line, and the rear of the driver is in a ported box, could be cool

Kinda depends on how much space you have . If you wanna make the most of 6 subs on a 6th order you'll need a large enclosure not to choke them. If you don't have enough space, a 4th order is ideal. If you do, a 6th order is a good way to get the most out of a driver without going crazy. The difference could be 100L/sub 4th order, and 150L/sub 6th order.

mids and highs would stay as is, hard to get more efficient without buying new components, and for sub I'd recommend a 4th, I've had good luck with 4th orders for outdoor PA, for a 12" something like 28L sealed, 28-40 ported, varies sub to sub. Tune it around 50-60Hz. Port should end up being 30x5cm, and about 25cm long, add a curve in the back, rounding over the front should help too, if it sounds bad just remove the middle baffle, and mount the sub like a standard ported box

Q is the ratio of reactance to resistance. It stands for "quality" because a century ago good radio transmission, and good radio reception, required antennas that delivered as much energy to the radio signal, and from the signal to the receiver, as possible--the resistance was a parasitic loss spent heating up copper. Since the thermal dissipation is (current squared) times (resistance), increasing Q meant arranging things so that current was low (so voltage high) and there were few and ineffective ways for the electrical signal to get converted to heat (both on the way out of the station and on the way into the listener's home. The claim that low Q drivers have a peakier response is incorrect. The maximally flat amplitude response vs frequency is obtained at Q = 2^^-.5 = .707 = sine 45 degrees (Butterworth); maximal phase accuracy Q = .57 (Bessel); maximal transient accuracy Q = .5 (Linkwitz); maximal efficiency (NOT sensitivity which is usually called efficiency but is not dimensionless as is every efficiency) at Q = 1.1 (Chebychev). Any value of Q greater than unity will exhibit ringing and overshoot. This was all worked out by the Australian mechanical engineer A.N. Thiele and his grad student R. Small and published in IEEE Transactions in 1961 (later republished in the Journal of the Acoustic Engineering Society in 1971 and 1972). Thiele realized that it was necessary to either transform all the electrical quantities into their mechanical analogs, or vice versa, in order to encompass both in a single framework that would enable the well-developed machinery of filter theory to be used. Unsurprisingly, being a ME he chose the former and--regrettably--published in the leading EE journal. By the time the word got passed quite a lot came and went: the Beatles, Jimi Hendrix, Janis Joplin, Cream, and Woodstock. Oh well. Note that total system Q (Qts) depends on the electrical and mechanical Qs (Qes and Qms) of the driver only--which varies widely (15% and sometimes much more) but is independent of the enclosure. Putting a loudspeaker mechanism in an enclosure raises the Q. You are stuck with it when the driver is unpacked--the only way to lower it is via equalization (the Linkwitz transform). The Qs I listed are in-the-box Qs, which you have some control over (a smaller box yields a stronger air spring which is more capacitive reactance, similarly a larger port yields a more massive plug of coupled air, which is an inertance yielding inductive reactance--like a flywheel.

You can get either more or less, depending on your choices for bandwidth and ripple, which are determined by the port size (mass), a series inductance = low pass filter, and the volume of the compartment it vents (compliance), a series capacitance = high pass filter. But TANSTAAFL, and bandpass designs require high precision execution because they have more sources of error in implementation and these can amplify one another.

Reports say HornResp, but I haven't had a good enough dive into the program to work out how.

Bass Box Pro

What program do you recommend for series tuned 6th order?

@@BARBELLS-AND-BUDS you can check out bassbox pro 6

Interesting. I've seen something which was a ported box, with speakers firing out, but also had speakers inside, so it kinda acted like a 4th order as well. I'm not sure what you'd call that, maybe a 4th quazi 6th series, as it kinda acts like a 4th and a 6th. But maybe since one is 2nd order and the other is 4th order, it averages out to 3rd order, so would in total be a 5th order. Yeah, an odd one certainly.

A 4th order. I have both and my 4th order is more musical and plays way deeper than my 6th. However my 6th does play louder at a narrow bandwidth so is good for spl.

Imay have missed a point to be as loud as possible at 1 note. sorry.
