6th order bandpass enclosure design ( port size matters ) Blender & WIN ISD

- This is my second attempt at designing a 6th order enclosure. 10 years ago, it did not go so well but today we have access to much better tools so hopefully we can make this happen!
( WinISD ) TS order
1. Xmas = Maximum Linear Displacement
2. Pe = RMS Watts
3. Voice coils
4. Mms = Maximum Moving Mass
5. CMS = Mechanical Compliance
6. Re = Losses Electrical Resistance
7. BL = Force Factor
8. Sd = Diaphram Area
9. Qms = Mechanical Factor
10. Znom / Advertised ohm

A router and 5/8" radius round over bit blend the ABS plastic(or PVC pipe) and wood together really nice. A little finish sanding and you'll have a great looking and sounding port. Sharp edges that the air turns across make the noise. You know air doesn't like to turn. Think of the short side radius in your cylinder heads.
Which reminds me! When the intake runner of a cylinder head is flowed, the intake flange gets a radius of clay or some sort of plate, mold, jig. Then the short side radius and valve seat are the radius at that end. Same should apply to your port. Radius both sides of tube. Just my 2 centavos.....
Nice Work U Do, Good Tech. TY For Video
1 3" port would be better also take up less volume if using sch.40 pipe
Was there ever a part 2 where you built the box?
Probably over the winter when car projects slow down.
You can tune a sbc like a boss and now i findout you are an audiophile. Im a fan of both. I need a dac for stereo home use, what can you reccomend bruh?
I can't really recommend one because I have never used one. Knowing how I am I would probably keep getting units and sending them back until I'm happy with the quality.
@@TPVPRO right on. I’ve got Klipsch RF-7’s powered by an RPA 14 Rockville 700/8ohm or 1000/4ohm or Bridged 7000 W at 8ohm. So I need a dac pre amp really.
I thought 6th order was when you have port from rear chamber ( being ported to front chamber ) then front chamber has a larger port existing the box/ whole enclosure ?
2 sundown x18v3....14 cubic feet box at 32 hertz.....can I use three 6 inch ports at 11.56 inches to reduce port displacement.....or do I need four 6 inch ports at 16.87
What did you end up doing? Hopefully you got rid of the 6-inch all together I would have used a 10in BAP or slot
Help me please . I'm studying WinISD software to build a 6th band pass. But I have the following doubt: The dm³ or ft³ of the box that I'm going to calculate, is it with or without the "maze"? Forgive me, I'm using a translator.
It is without the "maze" if you are referring to the port, no it does not include that.
Hi great video! I'm trying to tune a 6th order isobaric enclosure for 2 8inch subs. I was trying to tune both ports to 27hz to try get extra loud but in winisd the transfer order magnitude line just goes flat and doesn't show me the response. Is it not possible to tune both ports to the same frequency because it would cancel each other out?
You just got to run it through WIN ISD and find out.
Correct, it would just cancel itself out
@andriesgeddes4692- The louder/more eff. you make a subwoofer enclosure, the narrower the bandwidth. You can make a 6th order very loud, but it will be a 1 note wonder, and sound terrible with music. Also for max eff., and loudness, iso-baric, is not the way to go, i tryed it. You will be louder, with mounting your 2 subwoofers regularly= not iso-baric. For a higher SPL focused 6th order bandpass, type in these specs, try your 2- 8" woofers in a rear chamber of 1.5 cu. Ft. Net, tuned 8Hz below your peak freq., so try tuned to 37Hz, use 1- 6" dia. Round port( if its in a vehicle, the peak freq. Is usually around 45hz) and try 4.5 cu. Ft. Net for your front chamber, tuned 8Hz above your peak freq., so try tuned @ 53Hz with 1- 8" dia. Round port. This should be very loud between 43Hz to 47Hz!? If you wanted a much more musical 6th, try 1cu, net rear ch., tuned to 32Hz, with 20 in. Of port area, and 1cu. Ft. Net front ch., tuned to 70Hz, with 40 sq. In. Of port area. See how those spec. Out on your box builder program, there is a huuuuge difference between those 2!
Hello there! Do you also design/tune outdoor PA SUBS? Wishing you more power and knowledge from Philippines. 😊
WOW! First that Pioneer supplied bandpass enclosure specs. Second.....that they SUCKED! LOL! They're @ 1:1 and typically one chamber is larger than the other. I have no clue if that is directly proportionate to the tuning frequency, ie. small chamber lower frequency and larger the higher, but thats what my experience has been.
Winter build coming up right?!?!?!
Do you design boxes for people
If I ever get a CNC wood cutter I will.
How can I call you? Email? Thx
Hit me up on FB
Нихуя не понял, но очень интересно!😅
Hm.. Who needs to bump 80Hz I wonder? That's a boom-boom rather than a bass. If we need a bass with a good group delay, we immediately come to 200L+ cabinets, 1 to 6 ratios, and 1 to 3 frequencies. And then .. ta-dam we discover that it's comparable to 18" vented simple design. So. If you a car driver you spend your time with gluing 6th order for boom-boom. If you listen to music, you pay for 18" and relax.
How does speaker phase figure into this? Afterwards, did you try 0° and 180° ,if so which way sounded better?
I have never messed with phase so I can't answer that.
@@TPVPRO ahh,ok
uh, everything ive seen says the WHOLE outside volume of the port needs to be added to the volume required by the sub. As the volume of the sub itself, too. So did u say only half?, the port needs considered? if so why only half, i dont get it? Thanks!
Half of the chamfer not port.
@@TPVPRO ok
