Lexus NX Subwoofer

Mark Levinson upgrade? Not available in Canada as far as I know. It would have been nice. My package came with 10 speakers. I believe stAndard has 8.Looks like the Sub is mounted in the tailgate. Not sure if this is for both the stock sound system and the premium Mark Levinson upgrade...

Almost all newer Toyota and Lexus vehicles have subwoofer placed there. Great location IMO. Most subs from OEMs are the inverted type...so, very little depth is needed...so, they can fit literally anywhere!
The way most Lexus/Toyota OEMs (at least the higher ends) setup is to have a small subwoofer in the back/cargo to provide bass for the rear passengers...and minimally, provide a little oomph for front passengers. The bass for the front passengers is provided mostly by the front lower door woofers, which are usually oversized 6.5" or 6x9 variety. They provide most of the bass frequencies...the sub far in the cargo area is just to augment it (minimally). My guess is that the front door woofers (on 10-speaker setup) provide bass and no vocals...can you guys check? Vocals come from the midranges and tweeters in the dash above. Basically, the front passengers have a 3-way setup...tweeter, midrange, and bass/sub. So, technically, for front passengers, there is no need for the subwoofer in the cargo area except for maybe the deepest of bass...and even then, the cargo sub is only to supplement the bass pumped out by the front door woofers.
The rear doors has a midrange/tweeter combo and provide vocals only. Therefore, you need the subwoofer in the cargo area to supplement.
Toyota/Lexus a few years ago has gone to this type of setup...they called DSS. Distributed Subwoofers System. You basically have 3 small woofers (2 in front doors and one in cargo) that provide bass for the whole cabin. Contrast this to the traditional setup where you have only one subwoofer all the way in the back. Since most music rarely go below 40 Hz, this DSS system works great (and makes perfect sense)...no need for 12" or 15" subwoofer. But, by having 3 subs together, you can push out pretty good amount of bass throughout the cabin. And the smaller diameter woofers is able to give you cleaner (faster moving woofers vs. a large one) bass...maybe not as deep, but again, not needed for most music. Although bass technically cannot be localized, your ears/body can still localize it thru the energy being pumped out...so, in a traditional setup in a car, you need to ramp up the subwoofer in the cargo area so that the front passengers can "feel/hear" it. Of course, this kills the rear passengers because they can feel constant bass from the back of their heads. And for front passengers, you can still feel that bass is from the back of your head vs. being surrounded in bass. With Toyota/Lexus DSS, this localization of bass is eliminated.
(It is only for movies [bomb explosions!] that you need a big [large diameter] subwoofer.)

I own a NX 200t (Atomic Silver,Luxury Package, Canada). I have been trying for 5 months now to eliminate the rattle from the subwoofer. First, I placed pieces of foam behind my licence plate and yes.... the rattle from the plate disappeared. Unfortunately the vibration/rattle from the tailgate (the plastic cover) is still noticeable especially when the volume is up and bass setting above the middle. The Lexus dealer in North Vancouver suggested to have the bass settings changed but ....what is the point then having a sub ??!!
Wow, that is pretty poor service. No subwoofer if adjusted within stock settings should rattle at NX price range. My MDX subwoofer does not rattle even if you crank it up. What most of these systems do is just limit the max volume/output of subwoofer to prevent from overloading it and thus blowing it.
I think that you need to expect a certain level of vibration, especially when you have the volume turned up pretty high. Sound is vibration, so it is just the laws of physics that if you have super loud base, things are going to vibrate. The vibration is the base.
I agree with you but the vibration and rattlening is coming even before the middle of the volume scale (which is 25 from 50 max)
I am listening to pretty clear music from the USB stick (always 320 kbps) and I really want to enjoy the music coming from the "upgraded 10 speakers system"
Meanwhile I am just wondering if other NX owners can share their experience regarding the NX subwoofer.

Okay,today I listened beyond the Volume 25 mark. Yes, there is a rattle that is caused by the vibration of the sub, but it's not the body, it's the rear license plate casing. The rattling is not audible inside, only when you get out and go to the rear of the vehicle.
