Js, the subs don’t fire like a cannon lol even the design you claim is a no go will build pressure. still some useful information. coils being in ported section would not affect the pressure it’s capable of building. No difference in having two sealed chambers vs 1 for both drivers. If they are both to same space and tuning then it will be the same output.
hello i have question, many latin car audio use 4th order bandpas without port, my question is how to tunning the frequency without port like latin pro car audio thank you
Good video, thank you, question the Area that sealed off with a magnet’s are at , is that area totally sealed off , just the cones are open to the port?
I am trying to build a bandpass but it seems like I’m getting over my head as I want to have a port in the back seat center arm rest any pointers I have 2 10” deafbonce apocalypse rms is 800 max is watts is 1600 dual voice coil 1ohm I’m going to run them to 1 ohm the speakers didn’t come with all the specs as I try to run a enclosure program what hz am I looking for is there anyway you could help
I’ll see if I could donate so cash as soon as my wife comes home……. I even asked I some would design it and I’ll build it it’s been so long since I did this then my computer froze up. Any how I’ll hit you up. Soon enough
Hi, thanks for the video, helps a lot to get started. I have a question about a box. I wanted your opinion on. I have a 1965 impala that I would like to build a ported box and have the ports go through the back package tray. I am hoping this will help with the rattles of it being an old car. I am going to sound deaden the entire car, but I thought maybe a port through the back package tray would help eliminate some rattling. Looking to run a skar 2000 W amp and a skar EVL 15 inch sub.
I have a Skar EVL 18d2 and I wanted to either modify existing box or build a new 4th order.i have an 02 Ford expedition with as much space available.could you help me?it's a single
You mentioned you would help with a box. I need some help plz sir. 03 Tahoe. 2 12 ZVX V2 D1 with a RP 4500. XS Power 3000 battery. I've designed a 6th order but don't know how to get the volume I will need for each chamber. The tuning and all. How can I send you my design to see what you think? Have a blessed day.
Help help, I need a really good speaker box specialist … I’m building a 4th order enclosure, but I think all my numbers are wrong and screwed up -but the box looks great tho and amazing and all that… can someone help with any advice to tune my box to a healthy sounding frequency???
Very nice detailed video 👍 I am building a 3 way 4th order bandpass for two 10s 1cft sealed for each subs - 3cft ported so in total of 6cft in the ported box. A website tells me for a 45hz tune in a 6cft box with a square 10.86"by10.86" port It will need to be 17.2" long. Does this sound correct? And does the port of the ported box need to be inside or it can start out flush from the outside? Thanks!
Ported boxes tend to be more sensitive to precise volume "the extra mmf". Imprecise volume can quickly decrease the lifespan of a sub. Larger boxes lower the frequency, however one below the operating frequency which is easily done in a ported box can be detrimental
I wanna build one for two massive hippo 15s. 40"wide x 18" tall x? How deep would it have to be and how big would the port be? Help a brother out lol. Would the sealed sides have to be 2 cubic feet and what about the ported side what cubic foot? @mousetrap
New to your channel.... Great info..... I listen to many different types of music from 70s threw 20s everything from rap,blues ,pop, rock,country..... so how do I determine the frequency to go for..... and how do I come up with the frequency... I'm using SAVARD Rap 12s on a Zapco st 2000 xm 2... it's a mono block D class.... I want a 4th order blow thru.... 06 Chevy single cab.....
@@mouse_trap. Thanks.... I'm learning something from all your videos.... You are a good teacher and not boring....Lol... Looking forward to more videos and looking forward to picking your mind..... Especially on subs.... I been building systems since the late 80s.... And still learning.... Great Channel.....
@@mouse_trap. hey i sent you dm to see if you could help me out or point me in a direction to start doing measurments for a blowthrough i want to build but it said i can dm u
You never mentioned how you came up with 1cft sealed and 1.5cft ported. Also you always put the magnets in the ported side with the cones facing in the sealed side. If you mount the subs with the magnets in the sealed side you won’t be able to smell the subs if you over heat them. Bandpass boxes hide distortion so you won’t hear the subs distorting’ so you always put the magnets in the ported side so if they start getting hot you can smell the coils. Also that box needs to be tuned to 45hz or it will be a one note wonder.
Termlab program help design it….these specs are the truth…. Put the magnet on ported side don’t create pressure and smell them as well and more likely to blown them and never enjoy because the smell is gonna be in your head that you blowing them up …good design good power and respectable jamming = loud car for a good amount of time🔈🔈🔈
@@mouse_trap. Cool story bro, But It does not matter what direction the cones face to make spl’ smart people put the magnets in the ported side’ you can do whatever you want…lol
4th orders are less efficient than ported or 6th order boxes, they need more power to achieve the same levels but they do have much better bandwidth and arguably sound better and louder to my ears than flat walls or ported boxes.
Does box shape affect output? Id like to try playing with a 6.5 sub for behind my truck seat. I need a wedge shape. I already have 2 12s in a 3.7ft³ behind the seat
@@mouse_trap. can you give me dimensions on 15's that would help me out alot because I cannot seem to figure it out and I am a big diy'er lol love the videos
No... No..... You don't subtract the 1.5 from all of your dimensions. If anything you would add it. Because you start dimensions are what you want the internal of the box to be. And why do you have it inch and a half are you gluing two sheets of 3/4" MDF together for each wall. Seems to be overkill for 2 12s. Unless you have no bracing. But an inch and a half baffle would work just fine with the rest of it being 3/4 in. You also have to add airspace for your port to compensate for port displacement. So essentially you have to start out with your port in building a box because you got to build the box around your port. Because if you build your box and then decide your port it'll change the entire dimensions of your box. If you add the port later without changing the dimensions of your box your airspace changes.
You are doing your calculations the hard way. If you use Millimetres as your unit all you have to do is multiply all 3 dimensions then divide by 1,000,000 (shift the decimal point 6 places to the left) to get the volume in litres. Cubic feet are an inappropriate unit for speaker design as the unit are too coarse, unless you just want to do a sealed box. All the T/S parameters are metric anyway. Also using a spreadsheet will make your life a lot easier.
Wow I'm keep doing my box s simply this shit is like smoking crack or the new weed fu**dat .you know you know it looks right belive in your self this guy for other nerds
