My 13 TSX premium had a better subwoofer than this.

Switching it from -6 to +6 is literally barely any noticeable difference. Where as all my previous Acuras it was noticeable. Mirrors would vibrate/shake when subwoofer was maxed and maxed volume... My TLX I can barely tell there is any ?


Is everyone elses like this or is there an issue with mine?

 

I am not a bass freak but am an audio professional. Playing the jazz station on XM there is plenty of bass. On a purist basis--it's probably got too much. I haven't tried to adjust the levels but will try tonight and report back.

Same here.... The bass is non existent... Only problem I have with the car... Part of getting the tech package was the premium stereo that sounds like crap.

 

Makes me feel better this is an ELS issue. This sound system is actually garbage.

Bass literally is ZERO in this car

 

We have not taken delivery of ours yet but the 3 we test drove (Advance) add a decent amount of bass. We tested some bass heavy tracks from Portis Head, etc. to try it out and we were pleased. Also tried some very clean tight bass tracks from Pink Martini and it was great.

 

Have you tried to play music from a different source? In my TL with the ELS, SiriusXM sounds pretty hollow, especially with Dolby Pro Logic ON. If I turn off Dolby Pro Logic, and play music from Spotify, for example, the bass really thumps.

 

ive tried SVC off ... DTS off... all levels...

but the issue is when changing from -6 to +6 on subwoofer on all sources. There is literally no difference and i have to constantly switch it up and down to see if i can tell what's changing.

 

You may have a bad speaker / connection.

 

Have you sat in the back to listen or look/feel the middle of the rear deck are to feel the thump of the sub? If you don't hear or feel anything at all then there must be a problem. I have the base model and can definitely feel the sub.

 

Also... Are you adjusting the bass slider or only the subwoofer? On mine the bass slider provides a noticeable difference while the subwoofer slider offers minimal difference.

 

ive tried both

and that should be the opposite. Subwoofer should provide the main bass output in any car. its been significant in EVERY car ive ever owned.

The bass is literally non existant in this ELS audio and its pathetic for a premium sound sytem

 

Have you taken it in? Sounds like a problem with the sub or connection as others have posted.

 

I second and third the remarks that there must be a disconnected wire between your head unit and the subwoofer. Our subwoofers are clearly audible and provides bass that you can unmistakably feel in your butt.

 

I agree as well, the subwoofer in my car is definitely working... if a tad underwhelming. I've got mine set like this:


Bass + 4
Treble + 4
Subwoofer + 4
RR + 3
Center: Center
SVC: Low
Surround... still playing with it... When I first go the car I thought I liked it on, but lately I have been keeping it off.


Hopefully you can get this fixed quickly.

 

Yea i need to take it in this weekend... sigh

 

I have the same issue with my system is completely underwhelming. I don't think its a connection issue though. It seems under powered. I've tried all settings as mentioned above too.

 

What source do you usually use? I've noticed a pretty big difference between audio sources. I get decent bass through bluetooth and pandora, but almost nothing through fm (supposedly hd) and xm sattelite radio.

Maybe this is an issue of lower bandwidth music not being decoded properly by the various processing the car puts music through? I honestly don't understand how those svc settings work.

 

Some more observations on the sound system...

Music source selection is critical. Testing with CDs or USB where you controlled the rip quality seems to be the best. When I stream Pandora (the free version) through my MotoX , some songs seem fine and others have degraded audio quality (tinny/no bass).

One mistake I made which I have since rectified is fading to the rear of the car too much. Old habits die hard... use to the speakers in the back being the major source of bass. Turns out, that is not the case here. Now I am running as follows

Treble +4
Bass+5
Sub+5
RR+1
DNS off
SVC low

With this, I seem to get some reasonable bass. If you fade more - say RR+3, you can hardly feel any bass in the front.

Regards,

Keith

 

Wow! Next project is to look at my bass. I thought it was light on bass as well. I didn't hear or feel any thumping. I did notice that DTS Neural is off by default. With DTS Neural on, the system springs to life with great sound. No so much bass, still, but enough for me.

 

The bass is bad... somehow when test driving I overlooked this. I've changed the settings in almost every combination possible, and I also have the neural surround sound enabled. If you compare the specs of the 4G TL and the TLX, the TLX system appears to have less power than the previous els version. My 4G TL with the right settings was the most amazing system I've experienced so far... I've been trying really really hard to just get used to the TLX system but I'm still disappointed a bit.

 

You guys should test out deactivating or unplugging your ANC unit.
I am told by some turning it off in diag mode gets reset when the car is turned off.

But I have the ELS system in my ILX and noticed the system to be very underwhelming as well... though it is still much better than the average 7 speaker non ELS system.

Anyways, I unplugged the ANC unit behind the glove box and now have to turn my treble down because it seems to be too much and my rear view mirror now vibrates visually to the bass which I did not witness before.

Also, per acura, sound quality is better using the HD. However, while listening on a smartphone plugged in or via bluetooth you can change the equalizer far more drastically than your cars system. Turning my media player on my phone to bass+treble makes the bass really noticable in comparison to listening on HD where the sound is crisper but the bass isnt any deeper.

 

Sorry to ask, but what is an ANC unit. I read the entire owner's manual but I some time have a difficult time understanding abbreviations.

 

I found the bass in the TLX to be more than adequate for progressive rock.

ANC Active Noise Control?

 

there's loads of projects on driveaccord,net whi h involve bypassing the ANC module. I'd have thought though....it would do nothing with the car running the stereo with the engine off. Is there a difference when the car is on the move or stationary...?

 

You know thinking about it, did Acura totally account for the audio when designing ANC/ASC? Maybe it's reading some of the bass as noise to be cancelled? I'm going to unplug / disable it as I like my engine noise.

 

This is what some other guy have thought as well.

Originally, we started messing with the ANC (active noise control) because a guy without ELS installed a new sub and his car would make weird noises when first turned all. All from the speakers. A low drone buzzing sound. After a couple minutes it would go away I guess. But his sub was under performing from what he was used to. He unplugged the ANC as I did (i got the idea from him really) and his sub really kicked from that point forward.

I, with the ELS system but no aftermarket bass, swear I feel the bass and tremble has both increased. I wont rule out that it would be a placebo effect matched with some wishful thinking. But like I said, both treble and bass sound MUCH more defined with ANC off.

 

Can you point me where I can learn more about the ANC? I don't want to bore you with newbie questions, but I would like to disable mine, if I can figure out how.

Thanks.

 

From : 2015 Acura TLX: Interior - Honda.com


Active Noise Control (ANC) and Active Sound Control (ASC)
Keycontributors to the TLX's quiet, refined interior are Active Noise Control (ANC) and Active Sound Control (ASC). The two systems are comprised of dual overhead microphones, an ANC/ASC electronic processor, and the audio system's speakers. ASC/ANC operates whenever the engine is running, even if the audio system is turned off.
ANC is designed to reduce low frequency sound in the cabin caused mainly by the roughness of the road surface. The overhead microphones pick up sound waves and send them to the ANC/ASC processor, which creates and sends a precisely timed "reverse phase" audio signal to a special amplifier. In turn, the amplifier drives the door speakers to cancel the original noise signal.
ASC is a related technology designed to improve the engine sound quality by making the sound pressure level more linear as the engine revs increase. Typically, engine noise doesn't increase in a linear way with rising revs; instead there can be many resonances that create peaks and valleys in the sound pressure level and an uneven sound. ASC helps smooth out the engine sound by creating a same-phase or reverse-phase sound signal as needed and sending it to the speakers. Though the system offers benefits from idle to redline, it makes the largest difference in the range between 1400 and 2400 rpm (V6) and 1000 and 1800 rpm (4-cyl.), where it lowers the sound pressure level with a reverse-phase audio signal.
ASC is part of the Integrated Dynamics System (IDS). When the IDS is in ECON or Normal mode, the ASC system is tuned for a smooth, unobtrusive engine sound. When the IDS is switched to Sport or Sport+, the TLX's interior engine sound takes on a more aggressive note.

 

No problem.

Here is the first discussion the ILX and a few other guys had. A few posts in there is a video on where the ILX ANC is located. Not sure if this is the same for your car however.

If and only works when the engine is running, wouldn't an easy test simply be running the stereo in accesory mode (engine off) and seeing how different it sounds?

 

If *anc, not and... Is there not an edit feature in this forum?

 

Tonight I tried to get into Diagnostic mode, but I could not figure it out.

To my amazement, I heard loads of bass when I was in Accessory mode. I was surprised how different the sound was.

I tried the method referred to earlier, but I cannot figure it out. Can someone tell me how to get into diag mode? I did not understand the 1+6 part of the equation.

Thanks.

 

I added a small amp, box and 10" sub to my TLX. The factory sub was a joke for me.

 

Found how to get into Diag mode. Turned off ANC. Looking forward to the drive into work to see if there is an improvement in bass and treble.

 

does anc stay off? I have a feeling it won't unless you disable every journey...how do you get into diag mode? Same as Accord?

 

Wow! The ride into work was great. The ELS sounds like it was designed by a sound engineer, now that ANC is disabled.

The sound is much more clearer and has strong treble and bass components even with the default settings set to center.

Now I am thoroughly happy with my new BRP I4 tech 2015 TLX.

 

Yes. ANC setting stays off. I set it last night and drove into work today. Great sound.

I will find the link and get back to you. It was on the MDX site. The MDX ELS could be the same or must be close.

 

Thanks for all the birddogging guys! Greatly appreciated. I too think the TLX Premium system overall sounds anemic compared to previous 2013 TSX and three each 3G TL ELS systems, using identical music input on all three vehicles.

I sat in back seat of my TLX doing a test listen and the sound quality is very bad even compared to what's coming from front seat area and much worse than previous cars mentioned. Really miss the ELS system on my 3G TL's!

Don't know enough about ANC to chime in conversation but quickly learning. Thanks again!

 

Just turn the car on in Accessory mode without the engine running. I noticed a big difference. Supposedly ANC is on when the engine is on. In sunny South Florida, we usually don't sit in our cars without the engine and AC running.

 

It seems like an ANC system should be pretty easily programmed to ignore the specific frequencies coming from the music being played. If this is confirmed to be the problem, does that mean there is some sort of design flaw with the ANC not communicating properly with the media system?
