Currently hooked up via LFE.
Do crossover settings on the sub get inactivated when connected thru LFE?
On the Onkyo the speakers are set as full range,while the sub kicks in at 80Hz.
This is creating a boomy bass on some recordings.
At AC someone suggested I go with High current inputs on the subs and connect one of the Maggies thru it. This will then allow me to set the crossover at the sub.
The other setting on the sub are the initial recommended ones.
I'll try to help...
Yes, the sub's crossover and phase setting are disabled when input is the LFE jack. Those settings are functional when the Line input is used. Are you trying to get double bass from the maggies and the sub?
I'm a little confused when u say "On the Onkyo the speakers are set as full range,while the sub kicks in at 80Hz." My AVR's have always been "Full Range/Large" or a crossover selection. I believe the recommended setting is not double bass and pick a crossover. 80 is standard recommendation. Audyssey XT32 tried to set mine to 40, but i went with 70 to try for now. looks like your specs are 40-24 kHz, maybe experiment with settings from 60 to 80 set on your AVR crossover.
EDIT: A little more info
When you set speakers to full range/large and hook the sub up only the .1 LFE channel content is being fed to the sub, none of the other speakers content get's crossed over and directed at the sub. The sub would not play with 2.0 stereo content.
