I think I understand 4th and 6th order but my woofers are haven't arrived yet so I would classify them as "still on order".
I made a 16x subs band pass wall that I used for large outdoor events, it was the only thing that could evenly produce loud subsonic frequencies outdoors. This was before computer software calculations, all ear-tuned using oscilloscope, playing frequency by frequency 10hz all the way to 120hz, a lot of time real life tuning and AMAZING results. I started with 4th order then moved on to 6th order in series and parallel. 6th order is by far the BEST, most powerful and trickier design but computer software helps a lot nowadays. I had my subs tuned rear 22hz front 45hz and it was a MONSTER in subsonic frequencies, could barely hear over 80hz but I had other full-range speakers with woofers covering from that above. Also I could pump 3x the rates power without exploding the subs as the cone displacement is controlled by the port’s limits.
great video! very informative and really helped breakdown the differences.
Great bit on sub boxes. People new to lower frequency audio AND those with intermediate knowledge can take as little or as much information as they want from this video. VERY clear and direct information sprinkled with a bit of personal experience from yourself make this one of the best, most detailed explanations of how bandpass works and it's delivered with a lot of technical specifications while also being simple enough for those who don't have an engineering degree to understand. Bravo and thank you for this. You have gained a subscriber from me.
So glad you included the graphs! Love the data to back up the theory
Hey man I appreciate this video's explication of the 4 th order & 6 th order keep the good video coming.
one of the most interesting videos i ve ever seen !!!
Modelling a 6th order parallel bandpass I have found that it is best to start off by designing a vented box which is slightly bigger and has what is called the chebychev response. There should be a bit of a peak around tuning and a couple of dB dip in the centre of the range. A driver with an EBP (FS divided by Qes) of between 100 and 120 for tunings in the 35 to 40 Hz range and lower if you want to tune lower. Once this is set up on the simulator (I use hornresp) the second chamber should be around half the size and tuned twice as high.
Your videos are great-the best !!! Thank you for sharing your Knowledge.
You helped make my mind what style box to build. I’m doing 3 4ohm dvc.15 Skar DDX 6th order 25hz and 50hz with a sundown salt 4k at .67 ohm. With some lithium and a 350 amp alternator to Supply the juice. Should wake those subs up nicely. I can’t wait
Great video mate, very informative. Thanks for taking the time to make this help me a lot, cheers 👍
Amazing video and EXCELLENT THEORY👌🏾👌🏾👌🏾👏🏾🔥
Solid video, helped a lot. Thanks!👌
Thanks helped me understand more about Qts and 4th order. I'm working on a 4th order for a JL 12W6 for fun!
I built a 1:3 6th order bandpass with dual12s in an isobaric arrangement for my cousin's 1990 VW Corrado back in the mid nineties. That thing was ridiculous in the amount of output you could get out of it in such a small car. 130 dB or so if I remember correctly The 1:3 ratio also created an interesting big box on the bottom, small box on top sort of shape that gave me room to integrate an amplifier rack for the two Soundstream Reference 500s into one side of the top for a nice clean install. Took a while to figure out how to package it all into the small trunk and still leave some luggage room, and the final design literally came to me in a dream, the only time that has ever happened in my life. It wasn't the most audiophile solution I have ever come across, but it actually sounded cleaner than I would have guessed going in. Was difficult to balance the sound though, as the sub seem to be WAY more efficient than the front stage. Unfortunately some thieves took advantage of the clever packaging and made off with the whole thing after smashing the rear glass a few years later.
Hey bro! It was a great video. Helpful content. I was looking for this type of review.
Thank you, excellent explanatio video
this video helps a lot !!! thanks for the explanation !!!
Excellent work 👍
Lots of info here. Good pace..well spoken
