What is the difference between Large and Small settings on receivers?

[Kain]

Exactly, what difference does it make to the sound. Secondly, when should you use Large and when should you use Small?

KAiN64, in brief, the "LARGE" and "SMALL" settings are a rudimentary form of bass management. Generally, "LARGE" means the full range of available sound frequencies are sent to your speaker... that includes the low frequency bass that can create standing wave havoc in your listening room. When a speaker is set to "SMALL" the bottom end is nipped off at about 90Hz... and if you have a sub attached, the (progressively) lopped off bass will usually be sent there. It is your receiver or pre-amp that does the re-routing.

With the subwoofer power that you have, setting all your other speakers to "SMALL" is a good idea. The long waves of deep base are easily cancelled out by competing long waves of the same frequency. It is generally acknowledged that sounds below 80Hz are non-directional so sending them to a single Sub Channel, as in your case, creates a huge gain with no real loss... plus speakers freed of creating long waves do the rest of the spectrum so much better.

Hope this "thumbnail" view helps. HornEd

kain, as ed says & see your other post on the sub low pass cross. also, seb asked of this if you look further down the HT section here. i put together an archive on there of the benefits of an adjustable high/low pass crossover in the receiver's dsp. i'll just refer to that now
