[QUOTE="Flamin_D_Audio, post: 6309527, member: 614613"] Ive been doing home / car audio for a long time now and have lots of experience with ported and sealed enclosures, and as a project want to build a t-line for two 8" drivers, with the aim of getting them to hit as hard and low as possible (30hz). Ive researched and seen loads of variations, like some that are just folded lines, some that have a chamber before the line, some where the like gets wider, etc. I know my line needs to be 112.5" long to get the 30hz tuning i want, as im doing 1/4 wavelength. (Let me know if doing 1/2 wavelength will be considerably better). Just a few things to help me out: - How wide should the line be? Ive got a feeling its to do with the drivers Q** values? - Should it be a simple line, or have a primary chamber before the line? - Should the line widen? - Is there a 'best side' that the line should exit? Any help with this would be great, cheers for reading! Sam [/QUOTE]
