Possibly the worst subwoofer I have come across, it’s like something Matsui made in the 80’s
No wonder it resonates, you tap the box and it rings.
Just to make it better it would need deadening on the outside and internal baffle stuck on the inside.
And as for that speaker! My headphones have a bigger magnet!
I may have to upgrade the existing sub a bit as I plan to put a sub box in the boot and have a cable to swap to original when the boot space is needed.
I will update as I go.
I now have the speaker wading and some sound deadening felt. Going to set up a frequency sweep on an SD card and use my phone and watch the DB meter with a taped off area to place it to see where it peeks and film it then do the mods and do it again.
Bit primitive but should do the trick.
I'm not sure if Ash from audi retro fit is on here, but he had a tidy little subwoofer set up in the right hand cubby hole. He'd had the plastic shroud reinforced with fibreglass and a 8" installed. I didn't get to hear it alas.
So I’ve had it back out and modified it slightly and cheaply.
I will post up the waveform difference on the sweep test at some stage but it’s definitely better, less resonance during radio presenter vocals and certain songs, the bass seems tighter and lower ranges can be heard better now.
Cheap fix, it’s certainly not perfect but it’s a lot better until the Isobaric sub and amp can be fitted.
I'm getting one for the A5 but it is only for an 8inch. As the boxes are only around 8 litres their volume falls way below the very minimum volume capacity required for a 10" subwoofer and is only just acceptable for a shallow 8" subwoofer, this is what put me off trying to go for a 10".
But I'm clueless on these things so if somebody can tell me its perfectly fine to ignore the volume figures for an enclosed sub box for 10" then I might go 10 even though it sticks out into the boot space.

The box I've purchased in the listing is 0.9 cu ft and the 10" sub I have and plan to use is a Pioneer TS-W261D4 which has a Recom. Enclosure [ft3] 0.8 so I've provided the details and requested the box be built to the spec of the sub.
I had a 08reg A4 with the Bose system and the bass was full and present. Very deep. I loved it. Listening to music was a pleasure.
Now I have a B8.5 A4 with B&O system and I have to say the bass is extremely underwhelming. I've done some reading on this and come to the following conclusion:
The 12 speaker setup is all marketing BS. Music simply doesn't sound good with surround sound. Movies, yes! The B&O system has no setting for the Subwoofer level, whereas the Bose did. The B&O sounds good, but you have to turn Surround off.
You also have to adjust the settings according to the music source which you didn't have to do in the Bose. I know the Bose gets a lot of bad comments, not having nice fidelity and having boomy bass, but I don't find it to be boomy at all. The bass was deep and tight. I used to have the Subwoofer setting at 2 clicks past middle and it was beautiful.
The B&O just lacks deep bass. It's present, but if I wanted the same result as on my previous car, I have to increase the bass right up, but then it makes a thudding sound rather than tight bass. If there was a separate setting for Subwoofer like for the Bose, I would be interested to see the difference.
And as I eluded to earlier, the right music source is required, and the settings need to be adjusted according to whether you're listening to BT source, DAB or CD which is a bit of a nuisance.
Bottom line is if you want the B&O to sound good, or have better bass, you have to faff around with the settings, and if you like your deep punchy bass, it's simply not there. With the Bose, you had plenty of it and you had the ability to adjust subwoofer level. The 2 speakers worked perfectly fine as well
How can the sub on the B&O be so **** compared to the Bose sub?
