Few port questions...

[c0smo kram3r 0]

1 18" DC Level 5. Still waiting for some other bits to come in (amp/battery). But in the mean time, we want to go ahead and start on the box. We were thinking of these two options.

1) Sub up/ports up. Have sub in middle, with a port on each side of sub instead of a single port. Does anyone see any negatives to this besides using up more wood/cost more? etc... Basically would like to do it this way because OCD side is taking over, and we would like to keep it symmetrical.

2) Sub up/port back. This would just be sub up, with a single port along the bottom of the back of the enclosure. Pretty straight forward.

Basically, just looking for yall's opinions. Which do you think would work better/be louder? It'll be in a 05 Tahoe btw..

And once we decide exactly what we want, we'll be looking for someone to design it.

Subwoofers in question, number of subwoofers & subwoofer size 1 18" DC Level 5 (said in post)

Amplifier being used, specifically the model number. 1 AQ2200D @1ohm

Fabrication skill level pretty good I'd say. First sub enclosure, but pretty experienced with wood working.

Preferred material to be used (i.e. MDF, fibreglass, etc) 1" MDF, w/ doubled baffle, & def. some bracing

Vehicle which the subwoofers will be used in 2005 Tahoe (said in post)

Musical preferences Rap/Hip-hop

System goals ?? To be loud I guess even tho it's being underpowered? Confused by this question... Daily beater

Previous subwoofers you have used, and their installation particulars This will be the first

List any research you have previously done Umm... Read b/c I will be giving not much power to it, it will need to be built to larger side of the specs (around 6cu?). Definitely going to need bracing and doubled-up baffle. Somewhere b/t 30-34hz is what I've seen recommended.

Anything else?

Everything good.

I would suggest sub up port back, Under-powering is not bad for sub-woofers, Overpowering however is.

What answer in his reply would change it to port up? I'm trying to figure out how all the added info he posted changes the port direction other then spl or daily. School me! You guys tend to want to know all the variables to come to an answer and never explain HOW you come to said conclusion. Can't learn that way. I would have said port back based on the first question because that seems to be a basic rule of thumb in suv's. Which I derive from answers to questions like this. Which means I could be learning the wrong thing. See my point?

Woofer and port placement depends on a few factors, large woofers in large enclosures that take up the whole cargo area, sub(s) up port back, smaller woofers in less airspace either subs up port side, or subs forward port side in most cases.

I was kind of curious as to what some of that information had to do with it as well, but oh well.

But anyways, the vote is for sub up, port back?

Sub up port back for your Tahoe

[Julian 641]

For Suvs and hatchback style cars sub up port back is really a rule of thumb.
