After hearing and reading the praises of the econowaveguide's I have decided to start my own waveguide project. They will be called the Barzilaywave's. I have to thank PaulC for talking me into doing a econowave project.
I am having a tough time getting a grip on what I will need and want to make sure I don't waste any money buying parts that aren't right for the project.
Here are the details:
The bass enclosure will be using the Barzilay cabs I got from Redboy. The internal dim. are aproximately 22"w X 23 3/4"t X 15"d.
I mounted the Altec 921-8a's I got but they sound like poo.
I did some modeling with Boxplot and came up with the Dayton Series II woofer. It looks like it will work very well in this cabinet if my calculations are correct.

Now on to the horns.
I have a pair of 811b's that I can use. I'm not sure if they would be the best for this project. I know Zilch did some tests for jackgiff with the different Selenium D210Ti and D220Ti drivers on the 811b's. I don't know how they compared to the waveguides.
From what I can tell the best results were with the D220Ti on the PT waveguide with the Model 19 crossover. I am not married to the Altec horns and would be up for using the PT waveguides if this is what will sound the best.
I plan on using the standard 8ohm crossover per Zilches drawing.
Is there anything I need to do to "fine tune" this crossover to work with the Dayton driver before I start building anything?
I would like to get one of Jack's new crossover boards that he is making. I think it will make it a lot easier to build.
Does it look like I am going in the right direction here?
This is my first scratchbuild speaker project I have done so please bear with me.
