Port Size and Length

[NissanKicker 10+ year member]

Since you're wanting the subs on the flat piece. ( Not on the slant )

... You are limited to choice... I'll put a model of the circle port.

Here goes the model...

Either these subs are a lot shallower than I think they are... or that model is not going to work very well.

I don't think the port would work side firing would it? It will be right up against a wall. And what size is that port? Looks to be around 7" is that big or not?

Beaver, I'm glad you brought that up. I almost forgot the subs need to be mounted on the bottom half of the box. they have a 4.75 mounting depth so they have to be under that part of the slant.

lol... I shrunk the measures by 1/2 to get the entire enclosure... the top depth is only 1.75" on the model... It's actually 4.5 top.

with your layout, side fire port will not work, as you will have no space for the port to breath

Am I trying to build a pain in the a$$ box or am I just not understanding this very well?

 

[NissanKicker 10+ year member]

a pain in the A$$ box... You need more room.

... Try:

42"w x 16"H

Top Depth = 6"

Bottom Depth = 12"

Also, if 42" is your maximum width available, the box should be made 38" wide to allow for the port to breathe.

ok, how about this?

38x20 3.5top 10bottom

According to THIS a 2" diameter port would only need to be 2.16" to tune to 36hz in a 1.8^3 box. Does that sound right?

a single two inch port is gonna whistle like crazy. plan on stepping up to a 4" port, or dual 2"ers.

Also, the measurements you just listed make the enclosure 1.6cft. GROSS. once you account for driver and port displacement you're looking at much less... which will require longer ports.

If you can supply me all of the ts parameters I'll see if I can model something up for you.

38"W x 16"H

Top: 6"

Bot: 12"

Port: 5" x 5" x 25.5"

Tuning: 30hz

Here you go...

I'd really like to keep the top and bottom at 3.5 and 9.5-10 if at all possible. The height can up to 20" if need be

Like you stated... Pain in the A$$ enclosure.

... Someone else with alittle more experience give it a shot.

I know all too well about pain in the *** enclosures. GL with this one.
