Today, we talk about what is louder? A ported box or a 6th order bandpass?

Thank you for making me discover many more things about bandpass boxes, every day I am more in love with this configuration, which is a challenge to do for cars in my region😅......I wanted to take advantage and advance to a certain point, although yes, bass reflexes can ´´SPEAKE LOUDER´´ than bandpass-type speakers in a lower bandwidth range. Due to 6th order bandpasses having more capacitance and inductance agents, the application of higher power levels and cone control leads us to have a box system that will very possibly provide higher SPL ......I'm just leaving my vision for future exchanges of relevant information........a hug from a Brazilian admirer🙃😁

I forgot to mention the extra cone control with a 6th order bandpass. So, you are exactly right! They can handle more power built correctly and therefore could have an SPL advantage! Thanks for the input and thank for watching!

I beg to differ, switching from a port to a 6th the sound quality of the 6th was an improvement over the port. Reason why a port seems louder, is because a 6th is concentrating the sound waves forward into the cabin. But a slot port the sound waves just bounce around from the sub being exposed and using the trunk as a bandpass effect; which is also why ports tend to ripple trunks and panels and there's not much pressure in the cabin to get windy from wasted acoustic energy vibrating metal instead of projecting forward.

To accurately compare a ported vs. bandpass, you would need to compare either them both walled or both no wall, etc. If you compare a walled 6th vs. a no wall or trunk ported, the 6th will definitely be louder and maybe better sound quality as well due to what you said with the mixing of the sound waves with the rest of the vehicle.

@@caraudiolab both are trunk built enclosures. I wasn't interested at the time in gutting my car to wall it off. But trunk building, the MDF slot port enclosure I had vs the 5 cube 6th order made from burch I have now. My over all bandwidth is better now with my 6th and I'm close to hitting 150db on 45hz with -3db on the tone track and I was barely hitting 140s with the slot port

Like my old bandwidth was 23hz to 70hz in the slot port and playing lows in the 20z sounded muddy and port was chuffing. 19hz to 65hz is my current range on -6db edits like DJ Siryn and it peaks at 50hz with -3db on the tone in my 6th.

@@caraudiolab I got my 6th order last year from a shop that was gonna toss it out. It was originally a 4th order for 2 12s out of a world champion USACi trunk car. So I recycled it and made it a 6th order seeing that i had 2.5 cubes in both chambers and tuned the rear port to 24hz for them windy lows I love while the front port hits the mid bass frequencies still.

@@caraudiolab also slot ports are worse when it come to linear control of the soft parts. I've already torn tinsel leads on my Sundown Xv2 and had to recone it. But I've got plenty of cone control from the air pushing against the front of the cone in the rear port chamber of the 6th

nice work,do you know anyone that does designs these days for money ? im bored with what i have even though it digs down low,i have a 2 door 05 blazer totally sound deadened like over a hundred pounds of deadener with two X 12's with a 8 inch aero port it hits super low and loud,i also have a 18 inch nsv4 in my closet,i wouldnt mind talking with someone about doing something new,maybe something more windy if possible,life is flying by you know so hey,why not,im a old school basshead and i really like the idea of new designed enclosures like the tap horn or paraflex or whatever its called,one of my favorite boxes was a bandpass with two 12's back in the day,and it had a sealed side on the bottom and then the upper part came up a little over a foot or so with a removable lid that had a 6 inch piece of pvc dead center,it played amazing on all types of music but when i popped in a bass cd like bass 305 or something omg it came alive so yea anybody doing anything holler back ok.thanks

Is this a thing? I mean a 4th or 6th you still port size and tube the one side the exact same as a typical porter box.. the second chamber in a 6th is just another ported box sized and tube accordingly.. they are simply two ported boxes put together to flatten the response range some. One can not be “louder” then the other in a way I guess you can if you peak the ported box out for like a +12 then make the box little bigger to make it little less peaky. which you don’t want to do with a 6th unless you want it to sound like ass with music.

Awesome video, I have 2 kicker q class 8s in a ported box an there in there smallest recommend volume of .66cu net per with 4" aero tuned to 33hz. It does sound good but know kicker subs like bigger box's. My frequencys sound like in the 40s on up my subs are playing much so I'm wondering if it's cuse I'm tuned so low or since I have a factory HU and using the wavetechDQ I need to set my parametric eq to a certain frequency to boost the signal around those 40hz and up ranges. I'm gonna eventually get 3 sundown x8 d2 subs and run them in a ported box that will be close to 2.5cu net for the 3 x8 subs. Could you maybe draw that up and see how much louder/deeper I might be over my current 1.3cu net ported box with my 2 kicker q class 8s in. Thanks alot👊

Nice explanation. It’s funny but I never thought of a 6th order as 2 ported enclosures put together. I am assuming going isobaric would result in -3db across the board but would you get better extension because of the effects that would have on the enclosure size? Great job though.
@caraudiolab11 ай бұрын
The isobaric is really just useful if you want to make your box half the size. But yes, you still loose 3 db. However, a small series 6th with wind would be fun! I might have to try that. :)
@olekristianrannekleiv7628 ай бұрын
did you adjust the power based on bandpass tuning? 6th order band pass makes the cone move less, this means you can apply more power to force more cone movement, this in turn makes more output. I made an 6.5" SPL 6th order bandpass that outperformed my dual 8" fullrange speaker in bass output. the bandpass was tuned 37hz, 67hz. the full range speaker was tuned 35hz.
@caraudiolab8 ай бұрын
You are absolutely correct! However, I did not adjust for two reasons. #1. This can depend greatly depending on the 6th design. As an example, I personally designed/run a parallel 6th and it can't handle extra power like a series can. #2. I am assuming the same equipment for both the ported and 6th, which means the same power and subs, just a different box. Love the feedback though, I will have to make my videos a little more in depth in the future.

@caraudiolab I get your reasoning, I have a long time trying to find out what is most effective. My conclusion is that it is very hard to know. The most correct way to measure it is to divide spl on enclosure volume and use that number to define output per given size. Then, design the enclosure that is optimal for the enclosure type. If you restrict power, for example, then your condition is biased towards the bass reflex since one of the reasons why 6th order is so loud and powerful is their ability to handle extra power. I think what is louder depends on what scale you build. Below a certain size, the ports of a 6th order have to be bent to fit, making port size/shape the bottleneck that makes 6th order less loud. After a given size, ports becomes possible to be straight, aerodynamic and the correct ratio relative to the total enclosure size, at this point, 6th order I believe is louder, but only within a limited Band that I have yet to put a number on. I think your video was great. People are on different knowledge levels. If you are going to take all variables into consideration in a video about this topic, it would sound more like a research paper and most would probably lose interest due to too high complexity. ☺️

This is how I think about it as well, what gets the loudest per size. With bigger builds, I have started having to add a 3rd factor. What gets loudest per size and weight!

@@caraudiolab That is a good point, weight becomes an issue, that was actually quite relevant for one of my coming builds! Im going for a 130-150L bandpass sub. Im considering making it 4th order, but that demands even heavier subwoofer driver too.
