Since I normally run my speakers on small, I haven't noticed the problem with the DTS-ES LFE. Thought it was time to check it out, and sure enough, there was no LFE in ES mode. So, while checking out all of the other crossover settings, I found there is no redirected low bass from my center channel, using 2 different discs. My 950 will send crossed bass from fronts and surrounds to the sub, but not from the center channel. And that is both in DD or DTS. Has anyone checked all their channels/modes, and found any such problem? Even crossed at 150, there is nada coming from the center to the sub.

Any ideas, folks?

I know that this does work with the 80 Hz analog crossover. Somehow keep this thread active (I'm old, I will forget), and I'll test for this as soon as I have a chance. That Chesky Ultimate DVD-A/V disc has BM tests for each channel.

Maybe its time I got that. Is that the one titled Super Audio Collection and Professional Test Disc? I thought that was SACD........
Ah, further looking finds the Ultimate disc. Okay, I'll order that.

Anyone else had a chance to test this? I would, but my system is currently not completely set up.

The times that I've crossed over my center, there is definately signal being re-directed to the sub.

This is an odd feature to "break". I don't think I have it hooked up wrong; center is center.

How are you testing for this? The easiest way, is to find content that only has low freq center channel info (or at least a wide band signal). But that's easier said than done though.

I have several discs that have a fair amount of bass, Pitch Black, Castaway, etc. If I turn the fronts, or surrounds to small, then turn them off, bass below the cutoff freq. goes to the sub. Same setup for center, all other speakers to large, nothing comes out the sub (except for the occasional LFE) Since the center gets a very significant portion of the signal, there certainly is content below 150. In fact, if I set the xover freq. to 150 in the fronts, I can hear male voices in the sub.

I have meters that monitor the output levels of each channel in my system. Playing mono material and setting the center to "small" causes the mains to indicate signal.

I'm not remembering the full process for bass routing at the moment, but with the mains set to large is it possible that the low frequency from the center being passed to them? I know that the mains get all LFE when they are large and the sub is off.

You could try leaving the mains small and unhooking their pre-amp cables to see if the center's bass goes to the sub, I suppose...

I just talked to Scott, he thinks the setting of the mains to large sends center bass there. Sort of strange, wonder why? At any rate I am trying how to figure how to check that; what sort of a mono signal/which settings will send a signal to the center channel? Simply setting the mains to small sends that bass to the sub; I'm not sure that pulling the pre outs for the mains will do anything.

Hmm. The Chesky disc has a set of low freq only signals that rotate through the mains. When the low freq info *hits* a particular channel, there is a high freq beep through that channel. The idea is this: with all speakers small, the low freq content to the sub doesn't change, but where the "beeps" are does, so that you can make sure that the BM is working properly. I reckon that if I set all small, except mains to large, I should still get the beep in the center but the sub should fade away. I'll try this Thurs PM unless someone gets to it 1st...

Thanks, KCB. I ordered that Chesky DVD; they will be shipping it on the 7th.

Hello All,

When the center channel is set to "small", and the front speakers are set to "large", the bass from the center channel is redirected to the front speakers. Only if the front speakers are set to "small" will the bass from the center channel be redirected to the sub woofer. This is done because of the high level of dialog that occurs in the center channel. When feasible, "vocal bass" should be kept as close to the center channel as possible. This dramatically minimizes the possibility of hearing disembodied voice when you have a small center channels set at a high cross-over frequencies. This becomes most evident if you do have "large" left/rights where full octaves of voice are easily reproduced. A left to center to right speaker pan might inadvertently throw the lower registers of the voice to an obscure corner of the room. Conversely, if the L/C/R are set to "small", the effects are not as noticeable because of relative frequency consistency across the front.

Best,

Scott
