[QUOTE="KenMasters, post: 33396, member: 517"] [b]I read that "large" means a full range signal and "small" a bandwidth-limited signal ... but they both go to the sub-woofer?[/b] If you set the speakers to large, only the LFE specifically created for the .1 channel goes to the sub. If you set your speakers to small, the sub 80Hz (or whatever your crossover may be) information from the speakers is mixed in with the LFE channel and sent to the sub. [b]As I understand a sub-woofer usually has its own band-limiting filter, often including an on-board power amplifier. Would I be sending a full range signal to such a sub-woofer?[/b] No, the reciever sets the crossover and passes only the low frequency info onto the sub, the sub should then have a "direct" option which disables it's own crossover. Alternatively you can simply set the sub to it's highest crossover point (typically 120Hz) which should have a negligible impact on the reciever's bass management. Some people like to combine both the sub's cutoff and that of the reciever to achieve a smoother roll-off but that seems a little over complicated to me. [/QUOTE]
