1 - remove 3677 internal crossover network
2 - wire up the Crown XLS amp directly to the LF element (woofer) and HF element (compression driver)
3 - set the Crown to bi-amp mode and set a HF crossover frequency. What is the ideal frequency to set?
4 - Listen and enjoy ? Any bad effects?
My Pioneer boosts the HF to its target eq curve which is higher highs than xcurve. Essentially overriding the 3677 xover.
My pioneer also has THX modes, which is basically x-curve with other affects.
If one just wishes to apply some x-curve the Pioneer has an x-curve adjustment (reduces the highs). It can't be used with THX modes as they both do similar things.
After auto EQ, without THX or x-curve applied, just using auto surround on a hd audio bluray the sound is too bright for me at higher listening levels. And thats where I like to listen - higher levels.
Same thing turning off eq, I no longer need the THX or x-curve because the 3677 xover is getting through.
Do some searching on THX mode and you'll see a mix of those who like and use it and those who don't. There is no shortage of guys who prefer the x-curve/THX mode or similar.
Im pretty sure the 3677 has been overhauled since the 70s.
The O. poster of that thread sounds like a Klipsch salesman. Haha.
