Basshead15 Posted June 12, 2011 Report Share Posted June 12, 2011 (edited) So I'm trying to make a t-line for my pyle 8" (Don't hate) lol. I came up with a 56.5" long port, 41" sq of port, and tuning of 60hz which doesn't really bother me cause if I don't like it then i'll just go back to the drawing board. here's what iv'e drawn out so far. I'm not sure if I'm on the right track with where the 56.5" starts out at (I started it where the sub ends). I only have about 46" length-wise to work with so I tried to draw the bends but at that point at 2a.m. my brain was fried and I was just like wtf lol. So yea, help would be appreciated.

nCOMP1337 Posted June 12, 2011 Report Share Posted June 12, 2011 (edited) are there any other specs you can give? QMS, QTS, QES are each good to know for a tline, because they help determine if the sub would work very well, or so i believe you want a qms of less than 7, qes and qts of less than .4 Fs:60, Qms:5.23, Qes:0.89, Qts:0.76 it has a good qms, however, qts and qes are twice where you really want them to be you are on the right track, the second design in the bottom right would work good, you want the port close to the sub, you got the port length spot on, du to the mounting depth of the speaker and height, you will need at least 9 inch high port and minimum 4.5 in wide port, that would give you 40.5 sq in of port, which is very close to your 41 Edited June 12, 2011 by kynto Quote Link to comment Share on other sites More sharing options...

What's the importance of the Qes, Qms & Qts? jw. I'd prefer sub back, port however way. Edited June 13, 2011 by Basshead15 Quote Link to comment Share on other sites More sharing options...
nCOMP1337 Posted June 13, 2011 Report Share Posted June 13, 2011 (edited) to be honest, i am not sure why those particular t/s specs are important for a t-line, ive been told before just cant remember, but i know if you read the quaterwave T-line tutorial it talks about those particular specs and where you want them here is a rough estimate based ont he drawing you made and the port area and length needed this is just 5 min rough sketch, i can make a much better one in a bit, this was just to see if its what you wanted Edited June 13, 2011 by kynto Quote Link to comment Share on other sites More sharing options...

nCOMP1337 Posted June 13, 2011 Report Share Posted June 13, 2011 well, a U turn box like the one i made, is the simplest to make, less chance of any mistakes, and should perform well, in Tlines i Believe the least amount of turns allows for best performance, if you have the room for a b ox like this, this would probably be the best tline to go for Quote Link to comment Share on other sites More sharing options...

I have 14" (Height) x 46" (Length) x around 14" (Depth) to work with. What are all the dimensions n stuff for that?

nCOMP1337 Posted June 13, 2011 Report Share Posted June 13, 2011 (edited) Here is the one that is to spec 31 wide x 11.25 tall x 11 deep 56 inch port length = 4.67 cuft 40.5 sq in port area Tuned to 60.5 Hz For the cut out of the sub, I used 8 inches for the model, because the outer diameter is 8.8 inches, im not sure what the cutout is, so you woudl have to adjust that when cutting it out, but that wont affect anything else Cut Sheet List: Based on easiest way to cut (if you can make multiple pieces the same size, i thin that works best, this is how I tried to make the cut sheet) Top: 11 x 31 Middle: 9.5 x 25.75 Bottom: 11 x 31 Front: 9.75 x 31 Back: 9.75 31 Side without Port: 9.5 x 9.75 Side with Port: 4.5 x 9.5 45s: 3.75 (that length is before you cut the actual 45 for the wood, the side of the 45 facing towards the port is 3.75 long, the side facing towards the corner will be shorter after you 45 it) any other questions let me know Edited June 13, 2011 by kynto Quote Link to comment Share on other sites More sharing options...
STEvil Posted June 13, 2011 Report Share Posted June 13, 2011 60hz is way high.. Quote MickyMcD - "Capable of making some serious trouser flapping volumes at where's-my-testicles frequencies, the Servo-Drives used to be fairly jaw dropping..." Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through. Hammerdown... 1% no links to outside websites, business related FB/YT pages allowed.

Basshead15 Posted June 13, 2011 Author Report Share Posted June 13, 2011 (edited) 60hz is way high.. I'm not too worried about that, this is mostly for fun. Edited June 13, 2011 by Basshead15 Quote Link to comment Share on other sites More sharing options...
