So if that is how big the mouths are how big are the throats? Sorry for the confusion on the question.

Bjorn what size is your opening? 116cm2 throat:D

That would be one LARGE chunk of Mahogany that hopefully has a very low moisture content. Either way I am sure you will be just fine.

My 3.3" cost about $10 each. Then add in a CD and MDF scrap and I should be under 200.

Funny I was looking at trying to use my four 3.3" drivers with possibly a DE250 CD on a mid horn over an 18". Keep seeing threads like these to remind me to start something already.

If you were wanting budget why not build the DR 250/280 instead? You wanted the best so dont quit now. Just keep saving and then be done. I am still saving for my next build and once I finally get the next upgrade done I will be done. Wont be upgrading anything anymore. BUT I also wont be settling for mediocre either. If I had the room that would change some things also. But I digress.

I dont think cutting it in half would be the answer. If wanting to be cheap then just building ported boxes would have been cheaper also. 42hz tuned single 15" cabinets would be easy. Less wood costs also. I am still saving up for the straight dual 12" horn I want to build. Evert hing seems to take me years to build and I have a very small budget even after waiting that long.

Two cabinets like Dana's J2 design or something else? I am trying to figure out what your trying to do. And why are you trying to cut it in half?

Good to hear

Measure 3x's cut once. I know your pain though:)

Yes it is a ribbon. All honesty, I would think it would not have the horsepower to keep up. I can think of some other ribbons that would but those will never be an option. I would go with the Beyma TPL-200 if I really wanted a ribbon/AMT. But I know the Raal has just a touch more sparkle above 10Khz and above. BUT I will have to listen to the 402 before I say I need anything else. My experience so far is that on the highs on normal spl levels in a room I have never heard a CD that sounds as good as the AMT's or ribbon tweeters. BUT there are not many ribbons that are used for pro audio unless they are large and that would become a problem with directivity matching. The Raal supposedly can take 200w which in theory would be plenty loud for a tweeter. BUT the Beyma TPL can take a lot more abuse from my experience. But again I am only curious. I know that some of the Khorn upgrades have a Beyma supertweeter so I was only curious on that area of improvement. I know JBL does this on some of their larger 3/4way designs also but I have not heard them. So again just ideas. For the most part I am going to build a straight dual 15 horn possibly(JWC please ) or straight dual 12 design. JWC's Then add a EV horn for the top. Will have to wait some time to save for the 402. I will more than likely be very happy with the final combo. I just know that when I changed the mains in my living room I was amazed the difference in sound when I went from ribbon/amt's back to CD. And while that was shocking the one thing I REALLY miss are the dynamics you get fom these straight horn designs. Its been a long journey with very little money. So I am tryng to learn as much as I can and hopefully get what I want in a system in the end. Just looked at some PM's I have that were from 2010. I remember writing those PM's and it felt like a year ago. So this year I am finally going to make some saw dust. And hopefully my dual 21 FLH will be able o keep up with the mains.

What is the horn at the top? And what freuency does it cover? Always been curious about building one of these monsters but possibly using a Raal at the top. That being said I have never heard the 402 so I will wait to hear everything before I go adding ribbons.

Ya I think anyone that can read and draw would be just fine buiding this. DO we know exactly what parts I the plans measurements is slightly off?

Wow its coming along nicely.

Awesome to see some SH's mixed in with some Klipsch bass bins. I will be building a large dual 21" FLH for fun for my bass and hopefully someday have some SH's to go with it.
