Hi all. This is my first post in this forum as a new member.

I've had this beast for about 6 weeks (love it) and I've come to the conclusion that the Harmon Kardon Logic 7 radio is a real let down. Unless you blast it, it simply has no bottom end at lower volumes; even with the midrange and bass boosted all the way up. It lacks a "loudness" button or some kind of adjustment to give it some presence when the volume is down low. Its supposed to have 2 subs, but I'm not even sure if they are connected. Going to have my dealer check it out. With the Logic 7 circuit turned off, there is some improvement in low frequenceies but then the surround experience is lost.

Would appreciate any feedback or suggestions...maybe I should have spring for the B&O system, but the HK system is supposed to be highly regarded.

I have the same setup. My wife's C has the Burmester and it' blows my HK out of the water. I've found the bass is a hit or miss in my car. Either i have no bass or a lot of bass, nothing in between. I mostly listen to SiriusXM or Amazon Music in my car. Just turn the radio down and listen to the exhaust, that should make you feel better.

Coming from a crappy optional "premium sound" system in the Maserati Ghibli SQ4, I thought the HK is pretty good.

My kids Ford Escape is better at lower volumes than this HK system.👎

As heron 25th suggests, I end up turning down the tunes to blast the exhaust, but that's a whole other issue...

I have the B&O; it has lots of sound all around but in my opinion it is not worth the price.

And agreed with the above, the exhaust is where it's at. SPORT+ and sunroof open

Didnt opt for the B&O because i didnt think it was worth the money. But i did expect the HK to be pretty good. It's definately a let down.

I do love the exhaust, but i'm also dissapointed that you can't open it up unless you are in Sport +. My GLA45 has a button that can open up the exhaust in any mode. Also I'm not that fond that it downshifts into first when in Auto with Sport +. I'ts a bit jerky.

That is really annoying, I agree. It causes a lot of nasty looks from the wife (who's already on edge due to all the backfiring).

Your experience with the HK system is the same as mine. My wife's C300 has the Burmeister and it's awesome. I'm not complaining as the B&O is $5K which is ridiculous.

I did some testing with some subwoofer test tones on an SDcard. It's definitely not the sound system's capabilities. The subwoofer was kicking it from 20Hz and up. I think it's the source. SiriusXM is probably my problem since that's what I primarily listen to (love the jazz channels).

But I know y'all wanted that 808 can you feel that B-A-S-S, bass"


Here's some good test media

YES - the fidelity and dynamic range of SIRIUS overall has dropped dramatically as # stations increased - and for whatever reason some Sirius stations are "better" than most of the other channels .. have no idea why the inconsistency between different stations on a ongoing basis versus the majority/other.

HK is a "OK" setup - the better the source dynamic - the better the sound
