I used 3.9kohm and 0.27uF. The corner frequency is 150hz. I have Ascend 340 with two 6.5" drivers. If you have smaller front speakers, you can change the resistor to 5.1kohm.

Brian, any guide?
post #8493 of 15169
Having an external HPF cut off frequencies <20Hz would just be the same as setting 20Hz extension on the Rythmik, wouldn't it? The only conceivable difference would be the roll-off slope.

IMO, if you have no need/desire to produce content <20Hz and like the sound Hi damping gives you, set it to 20Hz, Hi damping.

My 2c.

Edit: If you did have it like this, there wouldn't be any need for 1-port mode either which really just extends the response of the FV15HP at the expense of output. Perhaps someone can comment on the sonic difference between 1 and 2 port modes if the latter concerns you in terms of potential SQ.

As long as ther is a subsonic filter in the audio chain, it will filter the harmful signal. But we don't want to do it too agressively as it will add group delay. If you already have antimode subsonic filter enable at 20hz or 14hz, and you wan to use 1port, you can use 14hz / high damping without a problem. If you use 2 ports, our rumble filter will have to engage, then you don't need antimode subsonic filter. In short, we want to have some protection, but we cannot do that without knowing what other equipements in the sound reproduction chain is doing. What makes the whole issue complicated is there is no standard. So each case is different. We have movies with a lot of subsonic signal and others not so much (even though both seem to have same amount of special effect). The main difference is the latter is already subsonic filtered. If that is the case, adding additional rumble filter will just add group delay.

5 volts rating would be sufficient right ?

Thanks for the clarification.
I'll leave it at 14Hz, Hi-Damping, 1 port mode (Rumble filter off). With subsonic filter in the chain (provided by Antimode), i hope I can play the subwoofer loud and safe for movies.

Interesting information, Brian. I don't know the video mikepos is referencing, but that sounds exactly like the issue I've been having. My FV15HP has tons of air movement and the loud flapping at 20Hz and moderate volumes. I am an Audyssey user. I wonder if it's possible to unplug the sub, run Audyssey, then plug the sub back in. Any EQing could be done on the sub itself. This is obviously not an ideal work around (I think Audyssey is fantastic for the most part), but maybe a possibility to use Audyssey and keep it from messing with the sub.

I finally got to flight in Denver and visit Woody777(Adam) and check out his subwoofer and see why he heard this flapping noise. I felt the urgency of solving this problem as it may not be perceived correctly from other potential customers.

We first listen to a 2 ch song and immediately I find the music bottom heavy. I suggested Adam to reduce the SUB level by 3db and then he told me boosted the SUB level after the Auddsedy calibration by 3db. So I am not against messing around with SUB level. But the foremost important thing is the sound has to be musical.

We then go though manual warble tone plotting. Everything seems to be fine except there is a -3db drop at 80hz. Audyssey calibration set the subwoofer distance to be about 2ft closer than the physical distance and Adam uses LFE inputs. So that is normally. I explain because he has Ascend 340s which can extend much lower than 80hz, so in order to get phase alignment, Audyssey needs to add phase compensation to the sub, which is equivalent to setting the sub distance closer. So "adding phase delay to sub" = "setting subwoofer distance closer"; "subtracting phase delay from sub" = "setting subwoofer distance farther". In short, we try different sub distance and it turns out the best result is what Audyssey has set after calibration. So we leave that unchanged.

Then we go on to the movies. We play a few movies that cause the sub to flap. The first one is the new THX demo track. It sounded again very bottom heavy. For me, all I hear is the boom when the floor is shaking and moving during crescendos or no bottom end at all at other times. There is nothing in between. So I immediately suspect it is the LFE mixing level not set up correctly. He and I went through all adjustment menu from Onkyo AVR and we did find the LFE level adjustment menu and Adam set them to 0db. My Denon receiver does something different so I was looking something similar on Onkyo. We play “Inception” and I again notice the bottom end is just too heavy. I asked him to reduce the sub level by 4db and listen again and the sound is much more natural now. We then played Dark knight rises. Every time the scare crow speaks, we can hear faint flapping noise when the cone moves about 3/4" without generating any audible noise (it is definitely a subsonic signal). That was with Dynamic EQ off and master volume level set to -12db. He comments that noise is actually less than what he normally would have experienced with Dynamic EQ on and master volume level set to something like -20db. So we tried that and indeed it was actually worse than higher master volume setting without Dynamic EQ. So this becomes the first problem, that DynamicEQ boosts the amount of bottom more than 6-8 db at the bottom end, which to me is a shock. I will come to this later in this report. But I ask Adam to search the internet again to see if there is anything related to LFE discussion of Onkyo AVRs and he eventually finds the mentioned of -10db LFE setting and he tried that and now everything is back to normal.

Here are a few thigns we learn:
  1. If you have Onkyo AVRs and your bottom is too heavy, check the LFE level again. LFE LEVEL does not equal to SUB LEVEL So boost LFE by 10db is not same as boosting SUB level by 10db. If we were to boost SUB by 10db and make it sound unnatural, we would have noticed that even with normal music. But if we set the LFE level too high by 10db, it sound like every special effect is a mini earthquake. It is just not fun to watch movies like that and we may not have noitced the incorrect LFE LEVEL setting as it only happens during movies's special effect. So identifying where the problem occurs helps us to find root casue.
  2. Dynamic EQ implementation is not fool proof. I commented several times in the past I am totally against using dynamic EQ as it was same as the "loudness" control in the old days and it was already proven not working. Here is the fundamental problem. Regardless your master volume setting, the bottom signal strength is always changing. Sometimes it is -60db, sometimes it is -20db, that means the dynamic EQ, if done truly to compensate loudness curve, would have to changing the gain dynamically on the fly. That is a nonlinearly operation. It is like chopping the time axis into smaller intervals and check the bass signal strength of each interval and apply different compensation based on the signal strength. It is a clearly nonlinear option. Now if the software does not do that. It just apply a fixed EQ boost based on master volume level (which is exactly what we had in the old days), it does not address the loudness compensation issue at all.
  3. I really suspect the flapping noise each time the scare crow speaks is caused by the internal clipping by erroneously apply 10db boost to the LFE signal. It overloads the DSP and also the digital to analog converter, which has the same effect as "clipping". The effect of boosting LFE by 10db plus turning on Dynamic EQ is the reason to cause the signal path to saturate and clip. This is very different from the flap due to over-excursion (or being over-driven).

There has been a reported bug with Onkyo receivers and Audyssey, involving boosting bass levels.

There is a meandering discussion starting here:

There has been a complaint of Audyssey XT32 or the Onkyo 818 boosting bass levels below F3. That singular user is not listening to the advice of enthusiasts much more knowledgeable and capable than many(including him or I). His system is overwhelmed by anything below 50Hz, he is not willing to add a sub, and he has run Audyssey about 100 times expecting a different outcome. As if the physical capabilities of his system, microphone, or room have changed. He is unable to distinguish between specs on paper and a microphone measuring in room. The only things that can help him are the things he refuses to try, the things that will not help him are what he keeps trying.

I also use an Onkyo 818 and Audyssey XT32 did improve my frequency response. It accurately measured my F3, and properly did not boost below that. Like most users it behaved as designed. I do measure with REW. It is an automated EQ tool that follows an algorithm. Clearly that algorithm does not improve his system and taxes the system effecting quality in a negative way. His choices are to 1) improve his system, 2) turn off audyssey, or 3) raise audyssey's crossover. I suppose there's always the possibility an Audyssey software developer went to the onkyo plant and convinced them to let him change the software on a handful of their receivers (basically this is his only shot at credibility IMO).

One bad user with a questionable system complains over and over, now folks are thinking this one persons experience holds weight over the hundreds of AVS'rs and thousands of other users whose experiences are positive.

A separate interesting comment I have seen lately is from someone who has 4 very nice subs, nice speakers, room treatment, ability to manual EQ, and ability to measure. He gets better result without Audyssey getting in the way, I can see that.

The issue with my Onkyo 706 is completely independent of Audyssey. The receiver is not properly decoding Dolby Digital and DTS tracks. It's pretty well documented in this thread, I just never noticed it until I got a really good sub. And I didn't have any need to research it until Brian came over and said this doesn't sound right at all.

I think the issue is resolved in most newer receivers -- your 818 is two (I think) generations newer than mine.

Hey woody, thanks for the background. The fella over in the 818 and audyssey thread has become a bit of a broken record lately and it has been urking me. I was not trying to say it had anything to do with what was happening in your system, just didn't want it to gain credibility by folks saying, oh this is happening to several people. The issue the 818 guy is having is different then what was happening with your AVR.

How friggin awesome is it Brian went to Denver to help resolve your issue. That is the best customer service I've ever heard of. I'm really pleased to hear everything is running better. Is this issue completely resolved or do you need more time to determine? I need to re-read the description but it sounds like crossover optimization, turning off dynamic EQ, and levelling the LFE to the mains (they were too hot before) are the sum of the changes. Is that correct?

Amazing customer service :-) So pleased I went with Rythmik. I told my wife Brian flew up there and she didn't believe me. I had to show her the posts. So Kewl.

By the way, does Audyssey not tweak LFE channel somewhat when it knows you are at -15dB and output accordingly somewhat?

If you have Audyssey Dynamic EQ engaged then yes Audyssey is constantly tweaking lfe as well as other frequencies so as to keep it as realistic sounding at lower volumes as it would if played back at reference. I think that's why it would sound horrible if you were to run your sub 10db hot and engage dynamic EQ at the same time.
My understanding is that the closer the volume is turned towards reference the less dynamic EQing Audyssey is applying and once reference level is reached no dynamic EQing is being applied.
I'm purely talking about the Audyssey Dynamic EQ function. Audyssey room correction has to have been run for the dynamic EQ function to work.

I'm a bit blur too. Does that mean the Onkyo 818 has problem with the LFE level, where it adds +10dB by default? I'm not sure about Onkyo, but on Denon, the LFE level can be found under Audio/Video Adjust > Audio Adjust > Surround Parameter > LFE. The default is 0dB, which should work fine on any Denon AVR (or any AVR in the market).

Yeah, never bump up the subwoofer level trim manually and engage DynamicEQ at the same time. The bass will be too much.
For me, the subwoofer level trim is left at Audyssey default, but I do engage DynamicEQ when I watch movie at -10dB AVR master volume. The bass is good enough for me.
FYI, DynamicEQ effect can be reduced through the Reference Level Offset setting (under Audyssey Settings).

Yeah to me it sounds like the audyssey calibration set the sub level too hot (or perhaps woody cranked it up a bit??), and that in combination with Dynamic EQ was just too much ???? maybe

You make me curious now as I am running my LFE trim 5dbs hot with DynamicEQ on, Dynamic Volume off all the time. Am I not suppose to? Most folks here are running LFE channel hot. I have the Denon 3312.

I believe Audyssey set it correct but he manually bumped up the subwoofer level and engage DynamicEQ at the same time. It should be either subwoofer level hot or DynamicEQ, not both at the same time.
But what confuses me is the LFE level mentioned by Brian (LFE level is not subwoofer level). He finally set it to -10dB and it sound better? Isn't 0dB the default for most AVR? Or the Onkyo 706 has faulty setting with LFE level?

How do you watch WOTW or War Horse (artillery scene) eek.gif
I belief most folks here run subwoofer level hot, not LFE level hot.
post #8520 of 15169
^^
I watch WOTW at -10 below reference with LFE 5dbs hot. I have not watched War horse yet. By saying subwoofer level hot, you meant raising the gain on subwoofer itself?
From what I am understanding, once Audyssey calibrated, one does not want to touch the gain knob on subwoofer but rather increasing the LFE trim on receiver.
