the mange Posted December 26, 2009 Report Share Posted December 26, 2009 I've noticed all these t-line enclosures are powered by ~500 watts. If I build a t-line for my friend's 12" tuned around 30 hz with 2000 watts, would it be beyond absurd spl wise? Link to comment Share on other sites More sharing options...
sven6977 Posted December 27, 2009 Report Share Posted December 27, 2009 i dont think 1/3 wave works. You are correct sir. In physics, octaves in this kind of setup follow the even lengths like 1/2, 1/4, 1/8. also, you could do a full wave.... it would just be a huuugggeeeeeeee box Rowan University Electrical Engineering LINK TO MY BUILDDDDD Current Setup in my 00' Hyundai Accent: Pioneer DEH-P6900UB RE.6.5C AUDIO 500w 6.5" COMPONENT CAR SPEAKERS Eclipse SE 6500 (6.5 coax in rear deck) two Kicker C124's in a t-line tuned to 28.6Hz Kenwood KAC-7204 US amps 1600.4 V2 Upcoming Build this summer: T-Line enclosure for two C124's tuned to 28ish hz O_O amp my speakers with a US amps 1600.4.

the mange Posted December 27, 2009 Report Share Posted December 27, 2009 That mainly depends on the woofer. what does your friend have? He doesn't have the woofer yet, but he's looking at a 12" fi btl (fs=37.9 hz, qms=5.28, qts=.19) or a Hifonics Olympus 2412 (fs=34, qms=3.8, qts=.513). What other woofers should he consider if we're building a t-line for it? Link to comment Share on other sites More sharing options...

If we're talking about a sinusoidal function, using a 1/4, 3/4 or 5/4 length it seems is tuning such that the wave is at a crest upon exiting the port: (referring to the bottom sine wave) Link to comment Share on other sites More sharing options...
antwan911 Posted December 31, 2009 Report Share Posted December 31, 2009 I tried out my first t-line enclosure today! Here's a link to a little video for your viewing pleasure. Link to comment Share on other sites More sharing options...
