Want to build Kestrel 2 clone

fin1bxn · 1st January 2007, 08:42 PM

I found some info and want to build a Meadlark Ketral ii Clone

I found the drivers
Vifa - PL14WJ09 Woofer
Vifa - XT25TG30 - Tweeter.

Cabinet
Transmition line - about 7 difractors inside(Coppied the 6 moons picture) and graphed it out to scale on paper so I have all dimentions. 15 degree slope in front
40 high
8 wide
12 deep bottom
4 deep top
2.5 x 6" open port 1" up from the bottom

I'm looking for a good crosover design and confirmation this should work

My understanding is that these speakers use only first order crossovers so that they have higher impulse response than most speakers. It is part of the design approach.

So you need to decide if you want to follow this crossover philosophy.

Yes, I will follow any plan submitted to me...I figure I will build a Removable back plate for the x-over this way if I want to change values or component parts in the future I can..

Thanks for your help

Additionally, the Kestrel II used an old style peerless HDS woofer, not a vifa.
