quick newb ?, When a manufactorer says like .9 internal volume sealed, does that mean the box should be .;9 internal volume sealed w/o the driver, or .9 sealed with driver? How do you calculate how much a drive takes up internal space?

i would give it .9 without displacement. usually on the specs it will have the drivers displacement listed.

generally they mean .9 sealed after driver displacement which is usually listed somewhere near the t/s specs in the manual

I would disagree, I would think they would list the NET volume (volume after displacement)

then why would most put the displacement of the driver on the specs.

For reference. If they didnt give the drivers displacement and the customer wanted to go with something other than recommended volume, then they would be swarmed with repetitive calls on what the drivers displacement is...

You won't hear a difference, so don't fight over it.Jesus lol.

So must of you say it recommend .9 after the driver is installed which means ill need around a 1.1 or 1.2 box correct?

yes.. the spec they give. is With the woofer in the box.

Ok, so how do you calculate how much the driver when mounted takes up inside space? is it one of the t/s paremeters?

It's usually listed or you have to ask the manufacturer. It's not a t/s parameter.

when it is listed is there a name for it, like volume displacement of something?

I usually just aim a little higher than the rec volume. Therefore, I think the volume listed means after displacement.

But like someone else said, the difference isn't very audible.

so you're saying .9 not counting displacement right? So .9+sub displacement, right?

I would disagree, I would think they would list the NET volume (volume after displacement)
arent you both saying the same thing? :confused:

know the first guy is saying without displacement. So he is saying the box without the sub mounted.

The second guy is saying the net volume meaning the box and the displacement or sub mounted.

First guy without sub

Second Guy with sub

Mike

I was thinking that. So i guess ill aim around 1.2 if i need 1 or .9 box volume

Thx

second guy said net volume, which is AFTER sub displacement....First guy said it was WITHOUT sub displacement aka not including/after sub displacement. Or maybe I just need to go to sleep :)

As an example, here's what stereo integrity's website says:

Sealed = 2.3 to 3 cubic feet.
Vented = 3.5 cubic feet tuned to 27 Hz.
The enclosure volumes above are after port and driver displacement.
15" driver displacement is 0.25 cubic feet.

ahhhhhhh so i guessing driver displacement is dd on other peoples web site cause i saw a thing in the enclosure part saying dd .20

i guess it that

Thx 4 the help guys
