[QUOTE="Jeffdachef, post: 8718224, member: 650438"] One suggestion for the sealed is to have a 50hz EQ drop/cut if your head unit/dsp has that band, narrow the Q factor a bit. Thats pretty much your cabin gain/resonant frequency you are at the mercy of in your prius. Making the box smaller will make this hump even larger tbh. For the ported box though, thats a lot of port area, definitely a design flaw imo. If you are using winisd for rear air velocity, you need to plug in the power after accounting box rise. So if your amp is 2000 watts at 1 ohm, you need to be looking at 2-4 ohm power because thats what the actual real world power will be. Meaning the amount of port area needed in a box is MUCH less than people think. From my experiences, too much port area makes the bass sound like absolute shit and sometimes you lose output and cone control. Too little is bad but too much is just as bad imo especially for SQ port area has a big effect on bandwidth and accuracy. I have better results shooting for slightly above the bare minimal to medium vs having too much in both SQ and loudness in my builds. I even have interchangeable ports and the big ones keeping the same tuning always perform like shit. sometimes its louder and peakier which is fine for competitions but most of the times the SQ and bandwith and tonality is just awful. A few other times its less loud, and sounds like shit and stinks up the sub so complete garbage results across the board. Just sharing some personal testing. [/QUOTE]
