like i said im still a beginner. what are those good for? iv herd those are hard to tune? Dont those have a high peak frequency?
You can tune a T-line just like any other enclosure but they are hard to play around with in cars because they are pretty large enclosures as compared to a simple ported enclosure
So how would they work on like a 15" or an 18"? say you have an 18" that is recommended for 6FT^3 ported, and you have the room for a box like that, would that sound better than doing a standard 6FT^3 box, 14sq^2 per FT^3 @ 32Hz?
Also...
how come the port gets bigger the farther it goes on?
