[QUOTE="stangme01, post: 457974, member: 554027"] no its not that I prefer dual gap technology subs in general in sealed enclosures. I was saying you get most of the benefits of dual gap technology in sealed enclosures because the only thing involved in making sound is the sub (no ports), and the sub has to use alot of excursion to get loud, and that is okay with dual gap technology subs because they don't distort much more at high volumes as they do at low volumes. But in ported enclosures, subs hard move compared to sealed, so they do not get much distortion due to high excursions as a result of BL dropping. Although almost all dual gap subs available right now have fairly high QTS, and IMO too high for porting for SQ purposes. I don't really like the SQ of subs ported when their QTS is over .4 subs with under .4 QTS (like the Magnum with somewhere around .36 i believe, and the PBX which has a .29 ) become much more balanced in ported enclosures. Thats why IDMAX's, IDQ's, Eclipse subs, and PBX, Magnum's sound so good ported (tuned correctly and in the correct size enclosure of course). As for the H2, it can sound really good ported but it requires alot of tuning with an EQ. I had to pull around 8-10db from 40hz, and 4-6db at 50hz, and 2-3db at 63hz to get it to sound really good.
