Could I ask your opinion? Currently running four sundown U15 V2 in a ported box (12cf net, tuned 35hz) in the cargo area of a 2000 Escalade. Powered by two surge 7k @ .5 ohm each. One amp per pair. Burping 154 @ 45hz sealed, clamping just over 12k. Currently designing a 6th order b-pillar. Leaning towards a 1:3 ratio (I want LOUD, rather than bandwidth) current design is: Rear 11cf net @ 30hz (12" aero port) Front 33cf net @ 50hz (30" "aero port", only a couple inches length) Most of my daily music is 30-50, that's where I'm most interested in it being nasty. Little wind would be nice around 30, but not a priority. I want my face ripped off in the high 40's area. The questions I have are; Should I go 30hz rear, 55hz front, or do you think 30hz-50hz tuning will be ok? (Unsure of cancellations as you mentioned, I'm new to this and it's a lot to learn) Current design has my subs in a wall (not flat mounted) with 12" aero port in the center, which is directly behind and directly in line with the front port. Would this be better/worse than say four 6" ports, one in each corner? (Four 6" I believe is equal to one 12") I'm unsure which would be better placement? The 1/4 wave of both ports aligns almost perfectly with the dash with the current design.

@@vivelawhiterose6459 Great rear chamber size, you may consider upping your front chamber some for those nasty highs. I would tune 28/56. If you tune to 28, it won't really pick up till 30 hertz and be loudest from there through about 60 hertz. The 4 ports may help even the loading out. The single 12" port will be most efficient.

People are absolutely choking off their builds when they do super small rear ports imo. It will net you more ultra lows, since it acts more like a leaky 4th than anything else. But that comes at the cost of any real boost to the lows in the main tuning range
@caraudiolab11 ай бұрын
I completely agree! The trend is to make the bottom/back chamber port smaller at the same time that subwoofers are gaining excursion! They are totally chocking their lows!
@blakebrockhaus34711 ай бұрын
Tbh I think the rise in high excursion subs may be part of why some guys do it. They've been told that a 6th is better for lows so that's what they build. But high excursion low motorforce subs make up most of the budget market, and those do best in 4ths. This is what I found with super small ports in my build. I tried out a single 4" aeroport for 2 12s and it behaved more like a sealed box until I ran into chuffing. But even then, the fact that I was choking off output helped because I could play all the way down to the single digits without completely unloading.

So ive always heard that adjusting the rear chamber tuning frequency will change the front chamber tuning frequency and vice versa. How would one predict this to reach a plan to build a baseline (prior to fine tuning through testing)? Or just use a generic port length calculator to find innitial port length for each chamber assuming the are not correlated?

@guhhran86142 ай бұрын
The reason why the Front port should be way Bigger is cuz the high er frequencies needs to be way louder in the car cuz they dont get as much cabin gain as the low Notes so you Design the 6th order to Boost the higher Notes more than the lower Notes which needs a way Bigger port. For Series tuned 6th order the lows also needs to go through the high Port so it must be even Bigger. Someone told me He would always Start with designung the low chamber like a normal ported Box, then Start to adjust the high chamber to the tuning and volume it needs, simulate which port size it needs in both chambers to dont chuffing and after that He adds the port area of the low port to the are of the high Port area and this is the final high Port area. Thats why i build a parallel tuned no wall 6th order, way smaller high chamber an smaller Port resulting in a smaller Overall Box. If i want to put in even more woofers in i would need to build a Series tuned since it gaves me more space for woofers but then it would be a wall build @@caraudiolab

What about Port compression in the rear chamber because of the small port area?
@caraudiolab9 ай бұрын
Consider you start with a big sized port, you should get pretty loud on the lows. As you shrink it, you will start to loose spl in the lows but gain wind. AS you continue to shrink it even more, you will still continue to loose lows and stop gaining wind but will hit port compression. Honestly, once you start to loose spl from shrinking, you already hit some port compression, that is why you start getting windier. Once you shrink the port to much, it acts like a 4th order that has a leaky box.
