B&O speakers in Avant vs saloon

[AZO1]

Audi info states that A4 B&O sound system has14 high performance speakers
I'm just wondering whether this differs in the Avant compared to the saloon given the absence of a 'rear parcel shelf'?
Thanks



On order: A4 Avant 2.0TFSI S line, metallic, Nav + AMI + cruise (= new tech pack) B&O, DAB, Parking Plus, valcona leather, Phone prep low, interior light pack

I'm also waiting for a B&O equipped Avant, and I've exchanged some emails with B&O customer care trying to understand the differences to the Saloon version.

Basically the configuration is the same except for the following:

• the rear speakers are located in the D-column;
• the subwoofer is located on the excess space for the spare tire (when choosing the tyre mobility kit instead of a space tyre)

Thanks Tiago

It makes sense for rear speakers to be located in D-column.
Just wondering about sub-woofer location if space saving tyre (default?) present.
At least it sounds as if Avant is not 'short-changed' on speakers compared to saloon, so sound quality should still be good.

According to B&O, you can only choose this option if you choose not to have the spare tyre...

:

Sedan Technical specifications

Front door & Front/Centre loudspeaker:
Two 25 mm tweeters
70mm full-range (centre)
80mm mid-range +200mm woofers

Rear Door & Parcel shelf:
25mm tweeters + 168mm woofers
Two 80mm full-range + 200mm "free-air" subwoofer that uses the parcel shelf as a baffle (like the A5)


Avant Technical specifications

Front door & Front/Centre loudspeaker:
Two 25 mm tweeters
70mm full-range (centre)
80mm mid-range +200mm woofers

Rear door and "D" pillar:
25mm tweeters + 165mm woofers
Two 80mm full-range

Luggage compartment:
A 165 mm subwoofer in an 11L bass reflex ported cabinet placed within the excess space of the spare tyre.


Amplifiers (for both Sedan and Avant):
Five 25 watt Class-A/B amplifiers for tweeters, mid-range and centre driver
Two 40 watt Class A/B amplifiers for rear woofers
Two 75 watt Class D amplifiers for front bass drivers
One 150 watt Class D amplifier for the subwoofer



Specifically regarding the subwoofer differences:


The Limo (sedan) has a 'free-air' subwoofer that uses the parcel shelf as a baffle. The A5 uses the same principle.

The Avant does not have a parcel shelf so we opted for a subwoofer in a ported cabinet. The only difference in performance is below 30Hz where the subwoofer port starts to roll off. This will make little difference to the listening experience for 2 reasons : 1. Most music contains very little information below 30 Hz. 2. This frequency area is masked by background noise while driving. The Q5 uses the same principle.

Of course it is possible to put a subwoofer in a sealed cabinet but the loudspeaker itself needs to be very large (as in the A8 / Q7). A ported cabinet can achieve good SPL at low frequency with a relatively smaller loudspeaker.


Furthermore, B&O also told me that:


Both cars are tuned individually as each car is unique. Further there are usually two tunings per car as a car with fabric seats and no sunroof will differ from one with leather and sunroof.

Excellent info there scottyuk.
I can confirm that the bass unit is located underneath the spare wheel in the boot in my b&o avant.

Hi there all,
i opted for the B&O system in my car and although the sound quality is excellent i was a bit dissappointed by the plastic grill covers on the top speakers/tweeters in the rear doors,just looks so cheap when you see that all the other main visible speakers have that lovely looking (ive got the B&O system) chrome B&O surround on them. Is it just me or does anyone else feel short changed by these tacky looking grills?

Thanks ScottyUK! I'm that "guy" and you saved me the trouble of finding my old post!

When I started looking at B8's I went through as much info/forum pages as I could. On AW I think I went back through 30 pages of threads!!

It's such excellent information, I just had to spread the word.

Glad to see you over here in the same way I'm over there

Please could someone who has an Avant and the B&0 pack tell me where the sub is located? The device under my spare wheel looks like a battery of some sort, not a sub woofer as noted by JOP.

Many thanks,

Mark
