transmission lines

[grahamfocal]

Hi I am a new guy here from the uk.
Just undertaking my 4th project in building a T-line set up, consisting of 4 cabinets.
2 housing the 2 150mm bass drivers, and the the other 2 cabinets housing the mid and upper units.
Due to the similar nature of t-line and closed box, the smaller mid cabinets are of that design.
The project will take me probably a few years due to funds and the fact that the units have a total of 22drivers and use a three way active crossover.
I work as a furniture designer, and design (I say design, I have adapted an older design that I designed probably 10 years a go now) loudspeakers when I can. I have been working on this design for the last three years on paper/autocad/solidworks programming, changing and generally faffing with mainly the cosmetic side.
Anyway, I am not expert so, no doubt I will be asking a few questions along the way, pleased to meet you all
Graham

Hi Graham,

Although I am not by way of any official, as another Member, welcome to the Forum.

You will see that there is quite a bit of interest in TLs here, and there have been a few threads quite recently with various comments on TL designs, so hopefully you should feel at home here.

Regards,

[grahamfocal]

thanks Bob, nice to meet you, I am sure that the info and help will go to make my perfect setup.

Hello Graham and welcome to the forums. Sounds like an ambitious project. Do keep us abreast of the progress.

Hi Graham,

Not sure about "perfect" , but there is a lot more interest on this Forum than I had appreciated until I posted in a couple of TL-oriented threads a few days ago.

If you come across it, I referred to the fact that I have had an 'ultimate' TL design of my own on the drawing-board (drivers in stock, chipboard all cut) for well over 20 yrs.

I hope yours gets finished quicker than this.

Regards,

me to, that humbles my time scale. It's also the fact that they won't fit in my current house/wife not letting me
so I have to wait until we move in three years or so.
gives me time to get them spot on I suppose.

The domestic thing is a problem, and I thought about changing the wife!

However, although we are now both into the 'free bus-pass' part of life, we still get on OK, so maybe I made the right decision.

thanks Cal, I will post bits time from time, pics hopefully to. hopefully be starting soon with the CNCing of all the ply, cant wait, it's taken 2 years to get this far.

Oh, I can't complain about my wife either with all of the gear I usually have in the lounge, but my girlfriend, that's another matter!
