I think my sub-woofer has failed. Anyone know where to get a replacement (apart from the obvious LR main dealer), there are several different ones list on ebay for instance but I don't know which one to get.

How difficult is it to get out? I assume it is in the left hand side of the boot. 2011 4.4 TDv8 Vogue SE

I also wonder if my sub_woofer is working. When adjusting the tone controls, adjusting the "sub" control from the extreme minus end to the extreme plus end has no effect on the sound. Would this indicate a non_working sub_woofer?

I have been having this dispute with Land Rover for nearly 12 months, mine is a 2012 and the Sub Woofer does not work.
They have changed the speaker twice, the amp and updated the software but nothing comes out of the speaker.
I have demonstrated this to many top tier technicians at Land Rover who agree that they don't work but they cannot fix it. Their excuse when I get the vehicle back is that it is identical to all other similar models so it is fine even though they agree it doesn't work. Their last play was to ask me to provide a chasis number of a vehicle that I have heard it work in and they will put mine on the same software. It will be interesting to see if anyone elses works on a 2012 model, all my previous Land Rovers worked ok but this definately doesn't. The spec says that there is 570 watts of digital amplification using Logic 7 processing...Like I say Land Rover say it doesn't work and that all vehicles are the same so tough....any advice from the pro team very welcome..... I need more help than most...sorry !!

I'll check mine for any output tomorrow.

I went through a similar process of thinking my sub-woofer had gone. No change in sound at whatever sub setting.
Dealer says 'it's normal'. Took the cover off the sub to take a look and there does seem to be some vibration but still no apparent sound output.
Might be my imagination but sound seems better after turning up the volume very high with high base and high sub-woofer for a few minutes. Trouble is after this I'm now deaf (plus I used to be in the artillery so deaf anyway!) Still no thumping bass like I used to get on my 2007.  2012 5.0L S/C

Hi Muppet
I did a bit of investigating this afternoon on my L322 (2011). I removed the panel at the left hand side of the luggage compartment and located the sub woofer. I was able to get my hand in far enough to be able to touch the subwoofer's cone. I had the sub level on the display set to max. Sure enough, the cone was vibrating. I then reduced the sub control to min and felt the cone again - nothing!

The conclusion I have come to is that the subwoofer is working but to a very minimal level compared to the volume coming from the other speakers in the car's interior. Even though I could feel the cone vibrating the sound level being produced was very small.

So I wonder if, in addition to the sub control on the display, there is another setting which controls how much power is going to the subwoofer?

Is it being tried with Logic7 on or off?

I thought the sub on my 2012 wasn't working properly as it couldn't really be heard unless the volume was high. The solution was to turn the sub up to full and move the front rear/fade towards the rear (about level with the front of the door armrests on the picture) resulted in reduced the front speaker volume and good impact from the sub.

Net result, with front speakers at normal volume, the sub has noticeable output.

Thank you so much for the info and tests you performed, and I think I agree with the last statement that it wasn't designed as a " Boom Boom " device...I will try the settings suggested to improve but agree that I don't think it is worth persuing especially after speaking the owner of one that appeared to work, he said that it was only noticable on certain tracks and this was one that I heard..

Really appreciate your help, advice and comments folks !!!! I need more help than most...sorry !!
