Looks like a 12dB per octave slope, which won't be enough for the HF. I'd want at least 18dB per octave.

Thanks Star

Thats a version of the arc line array, something that John built for the Military to be used under water, it does sound bloody good and can be heard from any angle without any loss Shocked

Am glad i went to him and had his expertise in designing and building the crossover

Resistors will burn though the wood and cause a fire as well.

But seeing as this is a low powered HI Fi cab you will be ok.

Honest mate, you would be better off chatting with Helen and getting the crossover made in China.
