With ported I don't lose any noticeable sq but it gets louder. The only problem I have had so far is some slight noise at full blast low frequencies. Even tho I have enough port area.
IB and I really like it, i just wish i had a second sub for more output on those days that I want to bounce down the block. but that's not very often so whatever
PPI Art A600.2, A404.2 & PPI P1000.1, FI X12, Alpine CDA-9887 Dyn Audio Esotar2 650, Dyn Audio Esotec MD130, Arc Audio PS8, JL Audio C5 4"
lots of sealed. i know this is a sq forum, but i wonder if most are doing like a single 10 sealed just to hear the lows, or maybe two 12s sealed for decent output?

Good answer. Every technology has its ups and downs. BTW, are you using a subsonic filter ?

The specs that Jacob at Sundown audio has from his testing are as follows -
POWER : 1970 Watts
AMP VOLTAGE (measured) : 49.25 V
AMP CURRENT (calculated) : 40 A
ACTUAL IMPEDANCE (calculated) : 1.23 ohms
SUPPLY VOLTAGE : 12.85 V
My speaker is a DVC 4 ohm/wired in parallel [ 2 ohms ]
I'm happy with about 1 cu ft stuffed and sealed/ inverse mount on an Image Dynamics IDMAX 12
At different times in the past, I have used 2 10s ported, 2 12s sealed, and 1 12 sealed. I also have a couple of 15s that I would like to try...just don't have the power or want to give up the space (for 1 or both).
I run a 12" IDMax in a 2 cubic foot ported box @ 32hz. The main reason: efficiency.
Before the IDs, I ran a 10" JVC Arsenal hemp fiber sub in the same box and it was awesome! It beat hard and hit low. JVC Mobile Entertainment \ 10" subwoofer - CS-AW8040 \ Introduction
It sounded like the sub was installed in my dash, I could not believe what I was
hearing every time I got in the car...very under rated sub.
I would def. go back to it. Infact, I am
I do use a subsonic filter though i cant remember off the top of my head where it is set. I also think according to winisd im good down to 15hz before my subs start to go past their rated xmax. how trustworthy winisd is with that not sure. i think i got it set at like 25hz cuz i dont think much music is below that anyways

good to see something different, ive used jvc head units, but never used their subs.
not sure if this is the place for it, but my thread over on CA didnt provide too much help
i have two polk audio mm1040 10" subs. i built a 2.3 cubic foot box tuned to 32hz slot ported box.
according to my calculations it has 31.5 port area. (port is 12" high by 2 5/8 wide)
i looked at the SSA box designs and for a dual ported box for two ssa dcon 10s, they have 28.125 port area.
polk recommended a box that has 27 port area.
on 99.9% of my music its fine as i dont listen to rap, but if i play late night tip, its making some noise for some reason.
someone suggested maybe its mechanical from my subs, they are rated for 700 watts total, im giving ~870. possible, but i dont think so personally. on that song, it takes putting the gain down to almost nothing to get the noise to stop, no way its power or clipping imo.
it is a 128kbps song, thats all i could get my hands on, and all my other music is 320kbps, and no problems with them. perhaps thats what it is.
iv have had sealed and ported. i had a JL 8W7 in the recommended ported box. it was a bit boomy for me it didint have the same attack as it did in a sealed box.
i now have an idmax in a sealed box. but i have head room problems (only 225w rms)
I have had in the past simple tuned port and single reflex bandpass for DB drag. For SQ I use 3 10's in a sealed enclosure. Great frequency response and so far I have not had a problem with low frequency reproduction. I did have a set of 12's in a hatch back in a sealed enclosure that was unbelievable they were bazooka 12's with a bazooka amp. Not sure on the power of the amp it was quite a few years ago.
