Thanks. The reseller already have that mathcad program and he did the calculations for me. So I am 85% sure that I am going with tqwt design. I have winisd and works nice for me. That driver in a bass reflex according to winisd will start rolling off at about 50hz, wich is a bit high for me, where as in the tqwtl moddeling, I can expect a sharp roll-off from about 35-40hz, wich is a bit better.

That looks good. Can you give us some more details about the design? How do you like them with your PP EL34?

Well, its a basic ported design with 16mm MDF wood. 33L volume tuned at 33hz. According to winisd at 100hz -1.1db 50hz -2.9db.

The sound is very detailed and accurate, but without a active sub, it is a bit thin. Output isn't a problem as I don't listen to music full-tilt. Over all, not bad. I really was looking at a 'all-in-one' box solution, but these speakers just isn't efficient enough for the tube.

One day I'll try something else, or buy myself a set of Klipsch speakers. :P

What you hear and what I hear may be totally different things, but I think if you give it another shot you could build a set of speakers that would make the Klipsch sound like a screaming child! :) I am not just dissing on Klipsch, they are not bad for commercial, but after interviewing dozens of speakers and then building my own I am sure that you can honestly build something so much better than you can find in that mid-end store. Plus, its more fun :)
However, I find a need for a sub as well with both sets I built.
