forgive my poorly drawn design. im in class and hurrying

tline on the left traditional on the right

my question is, will the tweeter being between the mids (also the distance of the line difference) mess with the effectiveness of the transmission line? would that setup (woofer, tweet, woofer) be better in a standard ported box? is there a different way to build a t-line to counter that differing plane issue?

I'd place the tweeter at the top, away from the woofers.

the tweeters between the woofers will create a MUCH better sound field. The way the reflections of sound will work you won't be able to identify where the speakers are. I like the t-line, but flip it...these are home speakers you want them at ear level.

i just designed a tline for my home setup, consists of a dayton 5 1/4 and a dayton dome tweeter. Its tuned to 55. If you want a copy of the design i can shoot one your way. I also designed the crossovers for it if you wanna see that too. LMK

hey this just helped me a lot (inadvertently) can you really have tweeters and mids in the same box as your woofers? sorry im sort of noobing out here but i want to build some speakers for my room and have essentially no idea how to get to where i want to go. also why is your tuning at 55hz?

 

masterbation is free, and even saves you money.sorry but someone had to say it

sorry, Jimmy...beat you to it (no pun intended)

 

LOLDON'T get a wife. Best advice I never got, and now it's too late <_<

My build: 12" DCON in a dorm room.

 

New/current build: 8" woofer, custom amplifier block, fiberglassed speaker pods

Tuning is to the Frequency setting (Fs) of the speaker. Its best to tune to the frequency of the speaker as it will push hardest at that and be most efficient. These towers are more for a great sound and quite honestly there going in a dorm room so i think theyll be more than enough. I get yelled at all the time for having too much bass as it is.

Definitely expect a build log. Crossovers showed up today and the tweeters should be here on monday. Gotta go buy the wood, and expect some granite on the faces of these during the summer too. heres a pic of the design

Remember guys, the crossover is just as important if not more important than the box with full range speakers :)

I'd pick what you want from the speakers, then choose drivers that match each other well, then design a crossover to match the drivers properly, then design the box to enhance it even more :)

how did you decide how to taper your box? as in how did you derive what dimensions to use for the mouth/throat etc.? thanks

My buddy did all the calculations and he's more the one to talk to on this so ill have him post up the calculations but we built one of the towers with what wood was in the school shop and basically to see how they sound.

Sound is good, found out that one of the mids showed up blown, so ill have to get another one of them in the near future. The final product will be 3/4 or 1/2 mdf with a 1 foot removable stand.
