It is not true.
There are 2 different setting for sub. One is cutoff and the 2nd one is crossover.
You can adjust the cutoff to take care of the LFE up to 120 hz. Cutoff is actually the roll off setting.
You sub's crossover should be the same as your mains.
The sub will still receive the signal from your surrounds below crossover 120 hz.
For example, if your mains' crossover is at 80 hz., your sub should also be at 80 hz. and have your cutoff at 120 hz for LFE.

This way the sub will receive signals from mains below 80 and from surrounds below 120 and will take care of the LFE up to 120 hz.

I hope it is clear.

You are not supposed to have conditioner for sub's amp.

This makes sense, im going to make sure my setup is like this. Thanks for the input.

My 4520 only has one setting AFAIK... I have it set for LPF as 120hz.

You should have several settings for your subwoofers. confused.gif

Each speaker should have it's own setting; mains, center channel, surrounds and subwoofer.

Ellis, on the denon menu if I remember right do the following,
1# go to speakers
2# go to manual
3# go to crossover
4# under crossover choose the top option to individual, there it will have each of your detected speakers listed individually and you can manually select each crossover. The sub will not show on this list, also unless all your speakers are set to small then this individual manual crossover setting will not be applicable.
5# go back to the previous page of the menu to manual, under the crossover setting is sub. Select this and it will allow you to input your prefered sub LFE level
Blackmambakila's Avatar Blackmambakila 12:50 PM 11-22-2013
Wait, is the crossover setting for the sub the one in the receivers settings and the cutoff the one on the back of the actual sub itself?
Blackmambakila's Avatar Blackmambakila 12:56 PM 11-22-2013
I get it, you set the speakers at 80hz and the sub to 120hz from the receiver and keep the back of the sub at 120hz or max right?

The Triax amp lacks any crossover adjustments; only level, power, and program setting. wink.gif

Oh...and a mute button.

The mute button wont be used by me much, lol. Unless offcourse i want to do some measuring without the sub, that would come in handy

Hehe....yeah. I accidently engaged it when I was first setting up (why am I not getting any bass??? eek.gif ) I stay far away from that button now. biggrin.gif

I had a panic moment too! When i first got the Triax all setup up I went to play something and no bass! I checked everything for a bit and still no bass! I was like no, not me! Then as I was checking behing the triax i noticed the power light wasnt on. I double checked the outlet and saw that it work. Then I was scratching my head. Well I didnt know that even though the power cord was in tight behind the Triax, your suppose to twist it! eek.gif I found this out on the instruction manual so I twisted it and behold, I was back in the game! Lol

Triax doesn't have HPF & LPF adjustment.
Look at your receiver for cutoff and crossover settings. The cutoff is sometimes called HPF (high pass filter).
Cutoff can be adjusted by equalizer but crossover is fixed.

I was speaking in general for people who had it on the back of their sub. Hmmm on this denon 4520ci, theres a manual option to change crossover settings for the fronts, center, rears, and sub. I have no idea of a cutoff option, I dont see anything else that has to do with this. I wonder if im missing something on the menu.

I am not familiar with odyssey. Maybe it adjusts the cutoff automatically and does not have the manual option for users to adjust it.

I did the exact same thing! I was just about to call PSA when my friend who helped move it figured it out.

I don't remember seeing anything in the manual about this and suggested to Tom that they include this info. Hmmm....I'll check the manual again, maybe I was so anxious I overlooked that part. biggrin.gif

Yeah that makes sense, ill probably investigate in an audyssey thread to find out for sure.

Lol! Thatd be funny if we called ranting on and then find out it was cuz the power cord wasnt on right! It did stump me because when you plug it in it seems to be fine but I totally missed the twisting part! I thought I might have been the only one lol

Yeah i think thats the way i read to put everything on the audyssey receivers. Other forums show variations but thats the way I saw the most people suggest.

Just to clarify for folks, there are different settings with different labels. Call them by the proper terms and you minimize the confusion.

A) avr's LPF of LFE. This is the Low Pass Filter cutoff for the Low Frequency Effects channel. It ONLY affects the .1 LFE channel. Since the specs for the LFE channel include content up to 120Hz, this is what it should be set to to avoid cutting out content in movies. This setting has NO effect on bass managed content. That's determined by the crossover.

B) Crossover settings. In most modern avr's and pre-pros, there is only a speaker crossover setting. Setting this to any setting/frequency (other than Large/Full Range) automatically sets the High Pass Filter for the speaker AND the Low Pass to the subwoofer. This setting can be varied depending on the speaker's low frequency capability, but shouldn't be set lower than double the speaker's F3 (i.e. if the speaker's -3db point is 30Hz, the XO shouldn't be set lower than 60Hz).

C) subwoofer LPF. The Triax doesn't have this, but on subs that do, when using crossovers (i.e. in the avr or pre-pro) and EQ, this should be set to the highest setting possible to avoid doubling the rolloff due to doubling filters (i.e. setting the sub's own LPF to 120Hz AND the avr's XO to 120Hz will result in a steeper rolloff).

So keep the avr LPF, XO and sub LPF terminology separate and you minimize the confusion.

I just checked my Triax manual. This is what it says;

"...The connector must be locked into place for power to flow..."

There's no mention about how to lock it into place.

I feel better now. biggrin.gif

Thats how I figured it out, when it said locked in i thought wait, i can still pull it out so that told me it wasnt locked and thats when i figured trying to twist it. Lol

Good post Blue, thanks for clarifying this. As a newbie to the game i was confused sometimes while searching around online for details with certain subjects.
