I'm setting up a new processor and am finding it difficult to choose an initial crossover point for each of our speakers.
Many processors use Lucasfilm's suggestion of a 'small' speaker setting with the crossover set at 80HZ. Nowheres on the Lucas website could I find out why they chose 80HZ, but it is a scheme that seems to work well.
Our new processor (a CB3) has extensive bass management capabilitles and the ability to use one of several crossover types set at any crossover point. My fundamental question is how do I choose the correct crossover point?
Our system is as follows:
ReQuests for both front mains and L/R surrounds 30~24000 Hz
Logos center 75~20000Hz
Two daisy-chained Descents 18~150 Hz
In theory, the ReQuests should qualify as 'full range' speakers (AKA THX Large) and probably dont need to be crossed over. Thats if you believe the published specs. Most ReQuest owners would probably admit that they fall a bit short in the bass department, to which I agree.
Obviously the Logos needs to be crossed over.
I think the Requests should be also, mainly to prevent over-driving the woofer on hard passages, particulary on tracks with extensive LFE content. But at what point should it be done?
I was hoping someone on the forum could look at the specs mentioned above and offer an educated suggestion at a crossover point for the two types of speakers we are using (Requests + Logos). Sure, the CB is quite flexible and it is easy enough to change a setting, but the configuration as a whole is quite extensive and I've never really given crossovers much thought.....at least not enough to avoid taking anything but a wild guess.
Thanks and sorry for the long post...
