Thread: Voice droning thru sub

Just getting settled into my new home, and was watching Bones and noticed some male voices droning thru the sub.

Audyssey set the LCR's at 80hz, and I have the sub at 120hz. Should I maybe lower the sub a bit?

I never noticed this at my old house, but Audyssey did set the LCR's at 100 before. Sub has always been at 120.

Thanks.

Try setting the sub at 80

Yea, I have my at 80 and never had that problem. I would do what DA Rizz said, then report back..

10-4. I figure, for experimentation purposes, is Ill reduce it slowly. got it at 110 now. It was a tad annoying during Bones, when Booth was talking.

Most sub makers recommend setting it to 80-85 hz as a crossover point.

Article from Home Theater Magazine

Speaker Configuration
The first thing you'll need to tell the receiver is what your speaker setup is and how you want it to handle the bass for each speaker in the system. In most cases, the options will be Large, Small or None. Often, these choices are limited in some way. For example, you can't select Small for the left front speaker and Large for the right front. You'll also be asked to specify if you have a subwoofer, and if so, the frequency below which you want the subwoofer to operate. Most (though not all) receivers offer a range of such frequencies; when in doubt, 80Hz—the frequency recommended by THX—is always a good place to start. It works well with most speakers.

The recent Edition Feb 2101 has an updated Configuration Article

Usually a good rule of thumb I use is setting the crossover approxmately 10-15 hz over your lowest spec.

Example: Your front speaker specs out as 54hz to 20hz, then you may want to try 70hz.

I have mine set at around 75hz, and dropping it down alittle eliminated unwanted booming and conflicts between the subwoofer and your mains. As in placement of your subwoofer, it's best to experiment to find the sweet spot for your crossover.

I did some reading on Def Tech's site, and it appears they recommend 100hz for the ProMonitor 1000 bookshelf and 100hz for the Procenter 1000.

I'm going to rerun Audyssey, and since changing the xover does not screw up Audyssey, I'm going to ASSume I should set the front and center xover to 100 and the sub to 100. This would have the fronts and center handle everything 100 and above, while the sub would take everything 100 and down. Correct?

TIA

You may want to try a sub like this for some DEEP base....

That is the theory. The idea is to get a smooth transition from the sub to your main speakers without excesisive overlap. Also, I would still play with the crossover and experiment to see what sounds the best to you. Best of luck.

Shit I got 2 of those babies with a 15,000 watt power amp, I don't even buy gas anymore I just bounce around town

Thanks. I watched TF2 last night for my dad, and I noticed the fronts and center were not doing too well. In my old living room, the LCR's were set a good bit higher than 80, so I feel it was too low. I checked all my speaker placements, moved the sub out a tad more to accommodate for the port distance-to-wall, then re-ran Audyssey. After it was finished, I set the LCR's to 100, the sub to 100, then re-watched a particular scene. Sounds better now.

The Formula your quoting is excellent provided your using a Pro sub from the same series so you will already have matching timbre, but if it's a sub by a different manufacture there will be some difference, try your formula and then tweak it from there.

Why is it that Audyssey recommends setting your sub to 120 after calibration, regardless of what the other speakers are set at?

So that there is no audio dead spot during the crossover translation...

Ah, OK. If the LCR's are set at 100. is 120 necessary for the sub or would 110 cover it?

It depends on the crossover. Try it both ways and see (hear) if you notice any difference. Crossovers work by sloping off the sound, incrementally at a point above the set point which would be 100 in your case which means the slope might start at around 120Hz.
