You would think that on packaged "system" like this A6, the "pad" should be built in to the crossover. It's not like I'm mixing components. This system was sold this way. Like I mentioned, the only think I can think of is that it was meant for an environment where a lot of ambient noise was expected and the HF is hot to overcome this. I'm sure it was not meant for a small room like my living room where someone would be sitting 9' away.

No doubt about it. They call them "large format" for a reason. One thing that I've read about is to simply swap out the diaphragms for the higher impedance type to help balance out a "hot horn"...If it's really overwhelming your LF, you can do both (switch to a 16 or 32 ohm fram and employ an L-Pad to attenuate the level).

Funny you should bring that up. I'm getting these new 300B monoblock amps soon. Supposedly they delivery a steady state 1.5W into 8 Ohms. I was planning on trying them with my 604s, which are 16. In my limited electronics mind, I was concerned that I would get less power because the impedence is higher. But in reality I would get 50% more power into a 16 Ohm speaker according to the designer. This makes sense since the higher the resistance, the greater the voltage drop across it.

So, by replacing the 8 Ohm phragm with a 16, would that actually help the issue, or hurt it?
