Well, the reasons for them using the ported side varies from my experiences. A larger ported side will be more efficient, thus more spl at the cost of frequency response, and some people want that type of response. Others i have talked with are just guessing and dont know what changing any of it does, so they are just doing with what they have seen. Btw, this thread should be stickied, because it is very informative and it would make it easier to find later down the road, especially since i sometimes post it for others to read. Hmmm, interesting. Because even at 2x and 3x events. World champions are using like, big 3 or even 6 to one ratio. But again, that's ported to sealed. Not as suggested by the cook book.

You ain't about that life Sen. Lol Yeah you right, i would really probably put an 5500 to it

Never heard of him, this is awesome stuff!!! Wow, you never heard of him and I have. That's a first, dude has been out quite a few years. I guess only way I remember is cause of the cool names Autobot and J2k lol Yeah, I will research him more

Don't think that exactly falls underneath the Trap genre hehe

Sean DeYoung, can you chime in?

Never heard of him, this is awesome stuff!!!

So taking another look at this write up, I've confirmed the results as well with other sources. The Vf value is the PORTED section, while the Vr is the SEALED section. So can someone please please provide an explanation, why EVERY BP Enclosure I see, the PORTED section is LARGER than the SEALED section? Generally speaking, the owner will describe their BP as an 1:1 / 2:1 / 3:1 ratio . And when they describe that's their enclosure, it, again, is referring to 1 ported to 1 sealed, 2 ported to 1 sealed, or 3 ported to 1 sealed. But this is TOTAL opposite of not only the cookbook, but other sources, including this write up by Quentin. I'm looking for a real answer to this question, not just, "their doing it wrong", or "because they seen it on youtube". Like, there has to be some truth to why the masses are doing it this way. This way being the ported section is larger than the sealed section. That's the first thing I have in question. Second thing. Continuing with this write up/example that Quentin has provided: lets set it to 25hz. I think that'll be low enough and we get: Vf = 1.387 (see we used the same s factor and it remained the same) Vr = 1.814 Qbp .1.08 fb = 43.65 hz passband = 25-76.21 hz (high f3 is a bit high but I'll use the filter on the amp to bring this down a bit. gain = 3.21 If the Vf value is 1.387, and the Vr value is 1.814. Does the Vf value INCLUDE port area, or is that another factor not listed? Do we even need to include port area in this calculation? If so, then how do we calculate the port area that is needed, and add it in?

Let me know please! Thank you!

There aren't any pictures, I don't understand without any pictures! What is all this reading nonsense!

No 6 spokes for the Trident? Will it still be able to reach peak xmax with the 12 spokes?

I see what you did there..

Yes, I use 2/0 from front to rear for mine, noticed a huge difference. minidsp.com would be cheaper than the RF. What blows my mind, is you can get something of much higher quality and for less, but that type of processor is made for home, and dj use, not really for the car audio world. So with something like the RF, just know, you're paying for the name mostly lol. Like I said, with a nice radio, and amp, you won't "need" no stinky processor.

take some pics! want to see that beaut

awesome sub!! For me, I would put an 2.3k amp on that puppy, port it at like, 30hz, and be prepared to drop the ladies panties! haha

This is how my enclosure from DC Creations came and it was fine.Ive talked with Dustin about his shipping methods. This semester will come to a close May 8th, so after that I'll have more time to think about shipping methods. awesome

insane how you get those octoports to look so "factory" looking. Like the transitions from port to front wall is just amazing!

Awesome

probably angle of picture Looks great though! Really digging the color scheme Would you offer an "additional service" type thing with the jersey's? For example, +3$ for each additional branding. So if you wanted to list a few of the companies on your jersey, you could do so.

I think I might have found the answers "I have the 2 ohm models and constantly play them in the low 11's and high 10's"

How did this end up happening to one? Was it low voltage or something?
