Yes , polyfil/acoustistuf can make box appear up to 1/3 bigger.
Designing a ported box tuned to 28 hZ will be good .

What are good subs (250 -300rms for a sealed enclosure forward firing at around the same price at those IDs?
Queef, I'm running kenwood kac 7204. Will mono it at 4 ohm so need 2 dvc 10" substhat will provide 250 or so each
This amp ? https://youtu.be/7ag22SZnU80
This is all I can find @ 4 ohm final impedance !

So for example, I have a sealed box thats tuned at 38hz. Each chamber volume is 1.2 cuft. The sub will fill up .5 cuft of that and I will have .7 cuft for the sub to work with. This would not be good because my box would categorize as a large box and My net air space around the same as the gross air space that's tequires for optimized performance. Are u following me or am I confusing the shit outta you lol?
Sealed boxes just are.
Ported boxes are "tuned".
Our ie box (intended example) is . .
Three cubic feet.
1) sub displaces , along with bracing 1 cu ft.
2)our gross of (3 cu ft) minus one cu ft equals (2 cu ft) .
3) how do we get back upto one-third , or a cubic foot ?
I will stuff it with acoustistuf until it plays lower notes .
How do we test it ? Apps might have a tone generator !
So from our gross volume of 3 cu ft , we have 2 cu ft left ( or ,net volume) and by stuffing it we can get back upto one third of our three cubic foot box.(or 1 cu ft).
Connect ea sub in series . Then with both subs wired til a dimm measures 7-8 ohms ( not 2-3 ohms) we connect the subs in parallel ( both of them to the amp ) . Our Digital Multi Meter will measure ?
( 2 ohms or closer to two than eight ohms )

The volume of this box was measured 1.2 cubic feet but for some reason this little nook wasnt included. It was written on the inside of the box when I bought it. Why is that and what should I do with it?
How am I to parallel subs in a sealed box? How does this work? Wires have to run from one sub to another but the chambers are sealed between them
