Mark Levinson 25 speaker sound quality is horrible.

So I love my week-old LX700h. What a ride! But the ML stereo SUCKS! It is NOT a full-length, 3-row system. ONLY the front speakers put out the main sound. From there all the way back the speakers just output "surround sound". So the 2nd and 3rd row folks just get low-volume "echo" sound. You can confirm this my fading all the way to the rear speakers (bottom of the touchscreen chart) then turning the volume up. All the ceiling, door, and rear speakers output only "echo/surround". TOTALLY UNACCEPTABLE! ME=PISSED! And this holds true in Normal, 2D, and 3D settings. ME=PISSED!

I love my LX700H, too, but the stereo system is unacceptable. I contacted Lexus USA and they are working on getting me a $2600 refund in the form of dealer credit for the lack-luster ML system. I'm planning on getting aftermarket woofers in the 2nd row doors (They have a speaker grill BUT NO SPEAKERS!). I think that will help. Maybe replace the 6 inch "subwoofer" in the very back. It's pitiful. I almost regret not getting an Escalade for the same price.

Just emailed my dealer res on this. Pursuing a credit.

You will need to go through LEXUS USA, and probably have your truck looked inspected by the dealer. They didn't offer me a credit at first - they said how can they make it right. I said fix it or get me my $2600 back. They've been working on this credit for 3 weeks, and it still isn't final. They have to get approval from higher ups due to the amount. I still may not get it, but my case manager says it looks good.

There is a thread on the GX 550 site about the Levinson in it... it might offer you some insight: https://www.lexusgxforum.com/thread...dio-sounds-terrible-on-the-gx-550-luxury.463/

That was a good read. The exact same problems exist in my LX700h. My biggest problem, since I don't sit anywhere but the front seat, is the lack of bass (below about 100hz).
