so a larger but not as long room will be louder than a smaller but longer room

with the subwoofer in the corner all other things being equal?

n by density i actually meant the subwoofer displacement is larger compared to the volume of the room

Not sure I follow your question. Are you implying that the air is more dense in a small room?

well the air in the room is more compressed from the subwoofer because the volume of air is smaller, i would assume that would help spl

isnt that what spl is at low frequency, a pressurized room by the sound wave?

i have a question for all you experts out there

i have always heard that room gain starts at the frequency which 1/2 its wavelength is the distance from the subwoofer to the farthest distance of the room

of course materials that the room is made of, etc take place but for the example i am going to use lets say there is 0 leaks and really lower resonance of materials used (ex concrete)

is room gain greater if the room is 10 feet high by 10 feet wide by 30 feet long and subwoofer placed in a corner (room gain starts at 19 hz i think) 3000

or if the room is 7 feet high by 5 feet wide by 35 feet long and subwoofer is placed in corner (room gain starts at 16hz i think) total volume of room is 1225

Now subwoofers are more efficient firing into a more dense air space (ex horns i believe relate here) and as the room size shrinks the ratio of subwoofer displacement to room increases, so i would think that there would be more spl increase in the smaller room even thou its longer

but cabin gain says the larger room is louder

am i comparing two different things here?

sorry for long post but thank you for any who try and help

thank you,

yes, but any subwoofer can bottom out with too much power

mostly im asking that if i want a infinite baffle set up can i build a high tuned ported box say 60 hz or whatever

and have an infinite baffle roll off in the lower frequencies?

well how about a fi 15" x subwoofer tuned at 32 hz?

btw i dont understand how this could be driver dependent, seems like a general thing

I got a question,

everyone says that playing a subwoofer below the port tune will cause the subwoofer to be unloaded, and with too much watts it will "bottom out"

is this unloading the subwoofer basically becoming a sealed box with a 4", 5",3" etc hole in it (loss of major amount of bass)

, or the unloading making the subwoofer box be like an infinite baffle, decreasing power handling, but increasing efficiency?

if it is infinite baffle, would it have a similar 6db/octave (i think this is close) roll off instead of a usual sealed boxes 12db/octave
