RE: Not quite here yet, bu at least I got ARTA/Limp up and running

So your graph is an acoustic measurement of your speaker for impedance and phase? I thought is was an electrical measurement of your dividing network.

It may not look bad, but it doesn't look that good either. I suggest you search online for the impedance plot of the Klipsch AA network. I think it will look a lot like yours. The impedance spike down low is what screws up the bass output from a SET amp. That peak is what you want to get rid of. I think you will have to fix it in the electrical realm before you start to try to tweak it in the acoustical realm. Maybe you should take some electrical measurements of your network with a resistor in place of the woofer.

Sorry Pix I am not an expert, and I can't answer any of your questions about bass enclosures, drivers, and ports. There are a lot of people on this forum who know much more about that than me. Hopefully they will chime in. I do know enough to recognize that your woofer is putting out significant sound a decade past your crossover point which can't be good.

I see you accept emails. I may have the schematics for the crossover I showed you on an old computer. I may be able to retrieve them, and may be able to forward them to you if maybe you were interested in them, and maybe if you agreed not to share them with anybody else. That's a lot of maybes, so I'm not making any guarantees. Let me know if your interested.
