Re: Single cab ported 12" boxes?

best option would be a round port with a 90 directly after entering the main chamber of the box placed on the opposite side of cab from the subwoofer

Re: Single cab ported 12" boxes?

Yeah, I was thinking of building the entire box across the entire length behind the seat, putting the sub behind the passenger and the port behind me. I was hoping someone had done a square port so I could see how they did that.

I'm hoping to get around 3 cubic feet with a port tuned around 33hz. Guess I'll have to see what others have gotten and give it a shot myself.

Re: Single cab ported 12" boxes?

square port in a single cab is near impossible with any considerable length because of the shape the box has to be

not really....my buddy never followed through with it but i designed an enclosure for him with a 10w3 behind the pass. seat and a slot port that was completely external...the port would follow the back wall and do a 90 behind the driver's seat...at also gave him a place to mount his amps...it was a killer design that modeled nicely but like i said,he never did it

that isnt a bad idea at all, i forgot that i designed one like that about 8 months ago for a 10w3 as well and i had the same idea with the amp, seems like i had a flat response modeled down to about 30 hz but i didnt do it becasue i have the brace cut out of the back of the cab so it would look wierd only coming up to where the trim originally came to and the back wall isnt pretty anymore

did some body say 10w3
not ported or 12's, but fits real snug and sounds awesome in my single cab.i didnt put the speakers behind the seats because the seats lay back into them.55x18x3 at the top and 7 at the bottom if you can use the same design and port it, it could fit 12's if i make the holes larger

Re: Single cab ported 12" boxes?

You could always fire the port out of the side of the enclosure if length isn't excessive. Run the slot port along the back wall of the enclosure.

If it allows enough port area to keep the port noise down, run a round or smaller square/rectangular port. The length may be shorter...or the port may be simpler to snake through the enclosure.

No pics( which I know you were hoping for ) but I had a similar set up in my mazda standard cab. I was running a single 10" cerwin vega in about 1.5 cuft tuned to 33 or 35 hz( do not remember exactly ). The box had a 3"x5" port firing into the passenger side cab corner with the 10" behind the driver seat. It sounded really nice in the truck and got relatively loud.

So you can fit a nice sized box behind the seat of a single cab. I'm having trouble figuring out how I could fit a port in there, square or round, though.

I used to run this SE in a 2.5 cu ft ported box tuned at 33hz, and it was great. I was hoping to somehow achieve something similar in my single cab but I'm not so sure.

Anyone have any box designs using a external port?

why do you want it ported? in single cabs sealed is the way to go, limited space. check this out.

Sealed Subwoofer Boxes
The most common and versatile type of enclosure is sealed. This style enclosure is ideal for any application where space is going to be an issue. In some cases a sealed recommendation for subwoofer box will be half of what the ported recommendation is. They also have the advantage over ported and band pass enclosures in terms of overall sound clarity. A sealed subwoofer box will deliver a tight, clean and accurate bass response and have a flat frequency response curve. In general a sealed box will be for listeners looking for sound quality driven system that is clean across the entire frequency band.
Vented & Ported Subwoofer Boxes
Next up are ported or vented enclosures, “ported” & “vented” are synonymous, it just means the enclosure has a hole in it to let air escape. You know that guy you can hear from 2 blocks away? Well he is likely running ported box. This style enclosure will likely be about twice the size of a similar sealed box since the airspace inside the chamber is much larger. Ported enclosures are tuned to a certain frequency range which is determined by the port length, width and diameter. The port can be in several configurations such as rounded or a slot which is narrower and taller. Each subwoofer will have a specific frequency they are designed to run at for maximum output. Depending on what you plan to use the enclosure for it can be tuned to various frequency ranges by modifying the port.
In general most competition SPL vehicles tune to high frequencies around 45Hz or higher. This setup would be designed for absolute maximum output but sacrificing a great deal of sound quality. A ported box tuned 25Hz will still allow your system to hit the ultra low bass notes while still keeping sealed like sound quality. The disadvantage is the enclosure will then have a fairly flat frequency range. And then the most common frequency range found usually in pre-built ported / vented enclosures is around 33 – 35Hz. At this frequency the enclosure will still deliver much more bass output than a sealed box but at the same type with still retain most of the sound quality. In other words you will get the best of both worlds with a ported box run at about 33Hz.
Bandpass Subwoofer Boxes
And last but not least are Bandpass enclosures. These are a hybrid box version and combine the features of a sealed and ported sub box into one enclosure. They are generally the hardest to build and design but offer some unique advantages. Bandpass enclosures are all about efficiency. How they work is a subwoofer or subwoofers in some cases are mounted inside a dual chambered box. One chamber is sealed and the other is ported / vented. The sound waves travel from the sealed subwoofer chamber though and out the port. This allows for a much deeper sounding bass and will be tuned to a narrow frequency band which creates a very aggressive sound. Not all subwoofers will work in bandpass enclosure so make sure you research or check the manual first.

Re: Single cab ported 12" boxes?

I just very much love the power of ported boxes.

I'll link a video of my SE in a 2.5cu ft box ported @33hz. Had a decent sound but got very loud.

*uploading the video to youtube just so I can show it off*
