Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Automotive Meridian vs...

I've been out on a listening spree today taking in the likes of Audi/Bose, Audi/B&O, Lexus, Jaguar/B&W and Land Rover/Meridian. Here are my notes from the day.

In all cases, I started off by ensuring that all tone controls were set to their default mid position. My test music was a CD of tracks including London Grammar, Katy B, James Blake, Daft Punk and several others covering music from the bass heavy electronic to acoustic vocal.

I should note that my hearing appears to be hypersensitive to 2-4kHz since taking some medication recently. However, it isn't very noticeable in the home environment, but the highly reflective and small car environment seems to amplify the effect.

Audi A5 2014 B&O.
Good extension 30/35Hz maybe, fairly taut bass, a little hump at 50Hz, a touch boomy around 80Hz, decent imaging, soft treble and nice midrange. A little forward in the upper mids. DSP set to driver sounded best for imaging and most natural in general. Some door panel vibration under heavy bass at high volumes (approaching 30). Seemed a little edgy in the upper mids at higher volumes although that might be my ears. Bass/treble control only available which can't correct for boom. Not sure if there is a sub or not.

Audi A6 Avant 2014 Bose
No driver position DSP so chose 'front' presentation. Similar bass to B&O although roll off higher at 40Hz maybe. Similar 50Hz hump and a little boomy also. Mids at 1-3kHz more pronounced. Want to reduce volume more than B&O. Good treble but not quite as refined. Rather than being soft, it sounded roll off at the top and more pronounced lower down (10kHz maybe). Not as refined overall.

The offerings from Audi are average, like going to Richer Sounds and buying low end hifi. I wasn't impressed.

Lexus GS450h 2011
Standard 10spk audio
I was hoping to hear the Mark Levison offering but the car only had the standard Lexus 10 speaker system. I was pleasantly surprised. Strong bass, deep and taut, excellent authority. Extension easily into the mid 30s but it was actually too strong compared to the rest of the audio spectrum. It wasn't boomy, just louder than it should have been. Sitting stationary, -2 notches on bass sounded more natural. Upper mids a little pronounced but ok for me. Soft refined treble. No rattle from doors or panels during heavy bass tracks although interestingly, the rear-view mirror was vibrating heavily, moving the mirror image visibly and making a rattling noise. An easy fix probably. To my surprise, the standard system has a centre speaker making the imaging pretty good. On the road it sounded bass heavy at the mid position, reducing bass to -1 helped, -2 was too weak. It sounded a little incoherent though; there wasn't a gel between the sub/bass, midrange and treble, like there was a hole between the sub/bass and the rest of the spectrum. Very pleasant to listen to and the car was so quiet on the road. I was seriously impressed.

I then listened to an IS300h Mark Levinson premium surround. Overall it sounded quite similar to the GS standard system but the imaging was terrible (sounded like a phase issue) and the upper mids were hurting my ears. I preferred the GS standard although I'm going to see another GS450h with the ML system to see what its like.

Freelander 2 2014 Meridian 825w
I checked out the Meridian setting, DPL2 and DTS Neo and the M setting was obviously the best. Bass was deep and taut. Extension to the mid 30s. No boom or humps. Mids beautiful. Upper mids a touch forward compared to what I'm used to with the 5Ks at home. Treble soft and delicate and good level of detail. Not as lush as the 5Ks though. The image was central until lower vocal registers when it shifted to the speaker door a touch. I also heard way to much from the surround speakers so I experimented with adjusting the fader and settled on 3 forward. This worked wonders for vocals creating a much more stable image in front of me but did rob the system of power overall for more bass heavy tracks. Some door panel vibration at really high volumes. Not sure I'd buy one as didn't sound as close to home as I'd hoped, although I think a lot of that was to do with the Freelander cabin, it's pretty big and sounded a little echoey.

Jaguar XF 2010 B&W
Out of DSP modes stereo, 3 ch and DPL2, 3 ch mode produced the most natural sound and the best image. With the tone controls centered, bass rolled off at ~40Hz, hump at 50-60Hz. Adjusting sub to max helped extension to mid 30s. Mids very good. Treble soft and delicate. Some upper mid forwardness, not as prominent as the B&O. Cabin muuuuuch nicer than freelander, no echo. Goes way louder than any of the others before it sounded strained. No rattles anywhere. Best results were bass -2 sub +8. Bass now down to 30Hz but perhaps a little hump at 100Hz. No combination could produce even bass. Pl2 mode just awful.

My order of preference:

1. Jaguar XF B&W
1. Lexus GS450h Standard
3. Land Rover Freelander Meridian 825w
4. Audi A5 B&O
5. Audi A6 Bose

The Jag and Lexus (more so) were both surprises and although they were different, I couldn't decide which I thought was best. The Jag/B&W's strengths was solid imaging and highly commendable overall sound quality, especially at high volumes. It's weakness was uneven bass response and I had to choose either extension with a 100Hz hump or a more even response but settle for 40Hz extension. The Lexus/Standard's strengths was nice even bass response, excellent imaging and a very easy listen overall but its weakness was a perceived lack of cohesion on the road.

I wasn't expecting them to beat M. I suspect that M in an Evoque would win hands down, though. I still have one more car to audition which is the GS450h with ML installed.
