Hi Friends,

My home theater setup includes the following:-

Denon 2309 AV/Receiver (100 W RMS/channel)
Quad 12 L2 Front Left/Right (100 W RMS)
Quad L2 Center (100 W RMS)
Quad 11 L2 Surround Left/Right (90 W RMS)
Definitive SuperCube III SubWoofer (650W Digitally Switching)
PS3 for BlueRay/Games
Sony DVD Player with HDMI

Going thru the settings on the Denon 2309, I came across settings for Crossover Frequency under Speaker Setup. If I go to the advance option, we can set the Crossover frequency separately for each speaker and SubWoofer.

By default these frequencies are set to 80 Hz.

What I understand from the docs is that this frequency is for low range bass sounds. If I increase the crossover frequencies, what would be the effect?

- Would there be more bass sound from the Front /Rear speakers?
- The highest range is 250Hz that is configurable on the Denon, will my speakers support it?

The crossover frequency mentioned on Quad Speaker manual says 2.2 Khz.
