Big Ports.

[bassahaulic 155]

Who is under the impression that bigger ports have narrower band widths compared to smaller port boxes?

I have heard this a few times in the last few days. I wanna if this is a common miss-conception.

Are you talking about vent size or box size?

I haven't ever noticed anyone saying a larger vent would decrease bandwidth....

Vent size. I hear it alot.

Can you give an explanation as to why it does/doesn't?

I wish I could give you the technical reasons for why large port don't get peaky, but I don't know for sure the reason.

[95Honda 486]

Until it stops acting like a port (Hemolitz Resonator) because it is too big (or extremely small), the only difference in overall response will be compression.

Any other differences people find/think they find is do to miss-alignment...

[shizzzon 461]

i believe you are referring to mechanical bandwidth?

If your design is using far too large of a port, it can cause the sub(s) to unload a lot easier reducing the available bandwidth that can be played for a mechanical reason.

[RAM_Designs 25]

A larger port will also have a steeper roll-off below tuning, from what I've noticed. Which kinda goes with what you said, Shizzon.

Not quite. lol I haven't talked to him in months. I've been building alot of boxes lately with fairly substantial, 20-22^2 per cube is what it works out to, ports and have see nothing but success.

Usually a very flat response, usually within a single db from 28Hz-55Hz with a tuning around 33Hz-35Hz.

But yes, if the design itself isn't right the woofers will unload FAR easier then a box with a small port. But there are ways to counter act most unloading issues.

If your having success with designs, why question them? We both know we've got these designs down pat, some people are just jealous

I'm not questioning it. lol

I'm asking who thinks big ports are peaky? Trying to help educate people.

Bass, I heard you were gonna design me an insane box for my 12" Icon.... Something smexci and awesome..

[shizzzon 461]

oh i have never heard large ports were peaky..

If tuned right, they are more efficient, obviously.

[bassahaulic 155]

I can do awesomely loud, awesome sounding, and epically efficient

I just can't do Sketch-up good. lol

[Shogen 325]

I'm not sure what I want... But epic is what I need.... Currently 2.5 cubes... tuned to 29hz.... What could I do for a more awesome sound?lol... I'm an idiot... If I go bigger on box design and stick with 29hz what will that do? Say go 3 cubes after displacement of subwoofer and port...? Can I expect any gains? I am looking for more umph at lower frequencies without sacrificing too much on the 60-85hz range.. Right now, I think it loses slight output at that range meaning the lower end in the 30hz sounds louder... Or should I be dialing more specifics into my amplifier? I'm at a loss right now... Should I just put more than 500w power to it and that should get me going? I'm kinda wondering ...

[Shogen 325]

would I be better doing some round ports instead of venting? I'm just curious, maybe I'm asking for alot off of my 500w JL amplifier on my Icon...

I have read recently that aeroports are peaky compared to slot ports, I have my doubts though.

I know SPL boxes can be peaky as they are supposed to b(large or small)

They are only peaky if you make them peaky.

[bassahaulic 155]

Shogen, PM me about what you have, what your goals are, and such and I can help.

I don't check my own threads alot of the time. lol
