2cf & 4" port too big for 10"?

[deucelee 0]

like the topic says, i'm looking to do a budget build. I already have an old 500/1 amp.

I'm looking to pick up a used 10w3v3 on ebay for like $110. I want to build a 2.0cf box with a 4" port tuned to 32hz.

Question is: is the 2cf box and 4" port too big? or am I still within the realms of "should be ok". I'll be giving it 500 watts. What it's rated at.

thanks.

PS: If anyone can name me a better sub for around $120 new or used, I'm still willing to listen.

Internal area has nothing to do with how much port area you need

That is bigger than the recommended 1.125^3 (iirc).

I would think power handling might be decreased with an enclosure that big.

i understand, but i'm just thinking it might be too big overall for the sub...

yeah i was thinking the same thing...the thing is i CAN comfortably have a 2CF box in my vehicle without feeling like i took too much space...

hmm, maybe i can go with a bigger sub...or maybe i can reduce the box and use a 3" port instead...

QUESTION: I've heard that 3" precision ports are usually ok with 10" subs, right? I recall that with a precision ports, you can go with a smaller port area then a slot port...

anymore suggestions for a sub for around $120?

thx 98gmc, will check those out

When you add port and sub volume, you will not have 2 cu ft net. (if your box is already a 2 cu ft gross volume).

A 32 Hz tuning for a small box require an extra long port, and will take much room in the box.

Go with what 98GMC told you, you will be very happy !

Sundown is releasing a new SD-2 line. The 10" is $125 on preorder. Check them out.

I am a big fan of JL Audio and Sundown. My choices would be narrowed down to either the used 10w3v3 or the Sundown SD-2 10".

Is that 2cuft externally? If so, a 10" is the biggest driver you can run ported.

Given the displacement capabilities of the W3, a 4" port is the minimum I would use.

not really, i am thinking about a 2.0cf net box. that means only a 13.5" long 4" port to tune it to 32hz. 98GMC has good suggestions but I think the SD-2 would be a better match since it's rated for a little more power.

the SD-2 seem very interesting and i'll have to think it over...good match for my amp

not according to JL...they're saying the 12w3v3 can use in a 1.75cf box ported

i was thinking that as well...that's also what carstereo.com was saying.

Try modeling the subs in WinISD It won't show cabin gain but you can see excursion and the port air speed. It could help you chose a driver and box.

And there is no way you can make a 1.75cf box NET and a port in a 2 cuft space. No way, no how.

sorry man, we're not talking about the same thing...i'm just saying JL says you can use a 12w3v3 with 1.75cf net.

even if i wasn't talking about that, i don't see how you couldn't get a 1.75cf net if you had 2cf of overall net space, i.e. internal volume. the 12w3v3 has a displacement of .07cf. One 4" port that's 15" long has a displacement of .11cf. That's 2.00-.11-.07=1.82.

if you're talking about a slot port then yes, i concur, you'd have a harder time getting the 1.75cf with a 2.0cf internal space.
