Denon Amp - Subwoofer crossover settings?

[JohnHolmes]

Using M&K 750s and SVS SB12+ Subwoofer

Have set speakers to 80 but am unsure what to set the sub crossover to?

You control the crossover via the AV Receiver so set to 80Hz for each channel (speaker) on the AV Receiver. Set the gain on the rear of the subwoofer at 12 o'clock and the crossover on the rear of the subwoofer all the way around at maximum. Run your Receiver's auto setup and then make manual adjustments as required. There should be a video guide on the WHF site, have you viewed it.

Cracking speakers by the way!!

Thanks I wasn't sure if it should be set at 80hz also!

On the Audyssey website it states the following about the LFE crossover setting:

LPF stands for low pass filter. A crossover requires an LPF and an HPF
(high pass filter) to work together. The LPF allows the low frequencies
to "pass through" and they are sent to the sub. The HPF takes care of
the remaining higher frequencies and they are sent to the satellite
speakers.

The LFE LPF is an entirely different thing. It's not a
crossover (because it doesn't come with a corresponding HPF). It is a
filter that is applied only to the separate LFE track that is found in
surround content. This low frequency track is added in the mix by the
people producing the content. It is limited to 120 Hz and below and so
the LPF LFE should always be set to 120 Hz.
