IB or LLT

Of course it's not "forcing" air if the port is large enough and sized right, I just meant it is moving air through a port, back and forth, If it's tuned properly it'll sound great, but with IB your speaker has equal pressure on both sides, no opposing force on either side, I was very skeptical before i built mine, my ported diy sub was awesome, but after finishing my theater, asthetically it stuck out like roach on a pancake. After the IB i'll never use a box agian, maybe in my living room but not in my HT. The sound is just "different" from any box or bass i've ever heard, it's hard to describe.. pure, effortless. People on the forum i'm not supposed to mention (on their quotable notables link) went on and on about hearing notes clearer and some notes other subs couldn't accurately produce or produce at all, basically redifining how bass should sound after years of boxes coloring their sound, they made it sound like it was the holy grail of bass. And after building my own, i must agree. I guess you have to experience it to understand.

My Ib consists of 2 Fi 18's with as i'm sure you know has over 14 liters of displacement, more than most 4 15" setups. I also have a 12" DLP in the living room and i just sold my titanic 15" sonotube (previous HT sub) to an eager buddy of mine.






I did read Rodny's IB Makeover thread , it sounds like LLT is on par with IB, and in some cases better and visa-versa. My experience is with commercial and DIY sealed and ported boxes, which in my experience can't compete with IB. LLT looks like it would be fun to try. But for now i'm completely satisfied- finally, and i need to quit spending money...that's the hard part!
