Thumping Noise from Mark Levinson speaker / subwoofer

It helped but there are certain raggae songs that I can't listen to at any volume level, just too much bass. I do plan to upgrade my sub eventually to a 12" so I can get my raggae and my George strait thumping again! Strange combo I know. I have a large pallet of musical tastes!

Thanks Lisa, I am the same way when it comes to music. I still think this is a fix that Lexus and Harman must fix. I do not know about anyone else but I drive around 55,000 miles a year and a good sound system make your drive that much better.

Where is the enjoyment of turning down the bass, some music is made to listen with base, and I only have mine in mid. That is almost what the service advisor told me don't put the volume so high.....that is like you give a kid a whole bunch of chocolates and take it all away in front of them while eating the chocolate.

Turn the bass down?
That's absurd, especially for people like me that get distortion at the mid level and even more at plus one or two. That's like telling the doctor your leg hurts when you bend your knee and him just telling you not to being your knee any more. I'm glad my dealer acknowledges the problem , it's Lexus that's being frustrating, I think the only solution is a sub that can handle what's given to it rather than revising the amplifier.

The issue is not the bass being to high. It is that the system can not handle the bass even at low volume levels. I should not have to adjust the bass down to -3 and keep volume down to listen to a song, then adjust all levels back after the song is over.

To adjust the bass, treble and mid-tones, press the RADIO button once and then select SOUND at the bottom right using the mouse.
"I should not have to adjust the bass down to -3 and keep volume down to listen to a song,"
You are correct, but until the system is fixed, you have no choice.

Well the choice we have right now, is to be on Lexus & Harman as much as possible till they get the point. This is uneceptable. If anyone needs the e-mails for Harman and united Radio let me know they need to know how disappointed we are with the ML system.

One of the reasons the ML costs so much more, is it's already optimized for the listening environment in each car it's installed in. A lot of engineering time went into setting it up and getting it as close to flat across the audible frequency spectrum as possible. Think of this like paying someone to come and do an ISF calibration on your home theater screen, and then changing the sharpness after the tech leaves because you like the picture more vivid.
I don't want to appear too cynical here, but I wonder if you've bought the ML ad copy hook, line and sinker. ML implementations across the Lexus line must hit their price points above all other considerations. Attaining flat FR is by design a lower priority.
Of course, you can bet the house that the flagship LS ML will get more attention than an ES or IS version, but don't be fooled into thinking that the marketing-speak "thousands of hours" of effort in cabin tuning equates in any way to the granularity of the work performed by an ISF-certified calibrator. To come close to this comparison, you'd have to do what I did -- drag your laptop into your car, take FR measurements with a real-time analyzer and re-EQ your music with a reverse FR curve!

I definitely notice the boost when in surround mode. However, it totally disappears when changing the setting to stereo. This is what I did with my 2ch advanced res DVD-A. If I had surround on, it sounded a little over done, so to speak. Did you try your experiment in stereo mode? I'm not sure the 2013 ML plays adv res 5.1, so maybe that's their way around your issue.

The Surround DSP function is designed specifically to synthesize 5.1 surround sound from stereo sources. How successful it is depends on the source material and your personal tastes. In particular, you may find the DSP works better on (uncompressed PCM) CDs than MP3s or satellite radio. Garbage in, garbage out, as they say.
So, with stereo sources, the DSP can be ON or OFF -- your choice.
If you are playing a DVD's 5.1 surround audio track, however, the correct Surround DSP setting is OFF, since it is already furnishing the system with discrete 5.1 audio.

I've been up and down and all over with my system. The bad FR affects all inputs. One thing, thankfully, that I found is if I enable the Surround DSP when playing CDs, it cuts the upper-bass hump down to where the sound is not ideal but at least listenable, and still better than the crap stock system.
