I have a 2018 F type R and I have never been satisfied with the Meridian system. I have done some research and it strikes me that Jaguar did not commission a sound system unique to the F Type instead they simply used existing systems from existing models, specifically the x351 (XJ) 2010-2012 and I believe in some cases the Range Rover.
The x351 came with two systems, the standard and the premium, they fitted the standard speakers to all F Types, rather than use the premium ones.
I have acquired a full set of premium speakers for my car which comprises of 2x titanium tweeters, 2 x mid range 4” Kevlar coned speakers and 2x 8” premium Kevlar coned subwoofers. Total cost £278. I intended to use sound deadening dodo mat (20sqm) £29.99.
So £300 to upgrade. I will wait for warmer weather to do a good job of the sound insulation. Will keep you posted. Ludders
