Advice Wanted for Build Tomorrow

[Joe89 10+ year member]

Hey,

Gonna do a ported box for a friend. 1 old style Type R D2 12", powered by a Directed Audio 600D, 600w RMS @ 1ohm. Going into a '03 Honda CRV. Doing a full install so I'll put a build log up for you guys starting tomorrow with the box.

I'm gonna do the box long and narrow, keeping the sub as far back toward the hatch as possible, the box will be the width of the woofer pretty much. Port back, sub up. I was thinking I would tune to 31hz. I want it to be loud but hit all notes, not straight SPL...

Sound good? Mostly looking for tuning frequency suggestions...

Let me know! Thanks!

Edit: How do I call someone out!? This guy had a sick box for the Type R's...

What was the net volume? Since the CRV is a bigger cabin, do you think a 31hz tuning be likely to yield similar results to the neon box?

Thanks! I see how to do it now

It was 2.5 internal Doubt the cvr will get as loud. Definately won't take as much power

Ok everyone, 2.5 ft^3 @ 31hz sound reasonable?? Build and see?

 

[Flastrongman 10+ year member]

yes the older type r's like 2.5 but 31hz might be a tad low on tuning. But that really depends on the style of box and port area.

Yes! You are here! If you would be willing to share the details on the box that pulled the hairtrick, I would be VERY appreciative! Feel free to PM me if you would rather do that.

So, 2.5 @ say.. 33hz? What would you do for port area?

 

[Flastrongman 10+ year member]

That box was around 2.7 per sub and tuned to 36hz with a kerfed port. It peaked at tuning.

Thanks dude. Any idea how much port area it had? I'm thinking for the 1 sub, I'll do ~40 in^2.

And very nice Photobucket gallery. You do some great work, any beginners looking for some inspiration... Check it out, the link is in his sig. @Montana comes to mind...

thanks man much appreciated. I can't remember the exact port area on that box, it's been a couple years. 40sq in sounds about right for yours.

Why do I come to mind? Calling me a beginner?! Oh wait.. I ez teh noob.


I've seen his gallery, in fact, I commented on it a while back. Told him how beautimus it was.

Woah, just watched that video, CRAZY for two 12s, I'd go as far as to say, insane.
