Improving the Sound Quality of an RCD-510?

Option 6 - 

Option 5, buy my Bentley GTC from me and get a free £12000 Naim Audio upgrade sounds very neutral

Snoops:

Where can one get the Scanspeak Absolute 1" treble drivers? Will it fit in the GTI's treble enclosure? Will it cause balance problems with the standard mid-bass units?
The other treble unit that has been recommended is the Morel Silk Dome Tweeter. But it is very expensive.
Any other ideas?

Lastly, does one have to remove the door cards to replace the treble units in the front doors even though the treble units are in their own dedicated enclosures? I don't have the car with me to check, so I'm asking you as I'm sure you'd know.

Door card has to come off to get at the sail panel.
Will they fit there no idea. I would go a-pillar custom build to reduce reflections off the instrument binical.
Moral not a fan too much even order distortion, non linear test results and not great QC in my experience.
If it was me i would replace the mid/bass first because i find midrange the most important to me and just highpass the standard tweeters higher then upgrade them later or you could just buy a complete 2way package.

Thanks Snoops. I have dealt in the past with Wimslow Audio for the treble units in my home Hi-Fi! It was ages ago and I have suffered many senior moments since!
I think I will leave it for now regarding the treble units and think about upgrading these in the future. The treble metal enclosure/grille does not help HF IMO.

Ooops. Read the rest of your post! Thanks.

It depends how low you run them and at what cutoff slope. In cars i don't like to run tweeters low and much prefer to keep them at 3.5Khz 24db/oct min or above that but this can cause problems if your midrange/midbass is not capable of producing the higher end stuff or its large and so has effects because of been off axis.

Interesting about the 3.5 kHz X-over freq. To my ears I have always found it difficult to accept. I have always preferred X-over at around 2.5 kHz, but then the HF driver might produce a bit too much distortion. Anyway, it's in a car, so it matters much less.
The way it sounds now, it is quite amazing. Maybe it is time I stopped fiddling.
When are you going to do yours? I'd love to hear it.

Driver seperation is the problem imo. To image properly and most 'in car experts' disagree with me on this as they like ~2.5Khz too but i can hear small chamber tweeters struggle with decent dB lebels due to midrange info out of them, anyway. If i have tweeters on the a-pillars and midange in the footwells for example.(helps improve pathleangths and angling) If i have the tweeters lowpassed low i can on certain songs get 3 images of the singer, one on either a-pillar and one on the centre of the dash. Dire Straits calling elvis is great for showing this up for anything crossed below 5KHz!
Mines on the list of things to do for 2011 just its near the bottom of it.

Lord, you know your stuff.

Should know alittle. I do moderate an audio forum run by an incar sound quality multi world champion and have been into this stuff since the late 80s.
OT: My views on audio are not always the norm, As i have been on the other side of audio and seen how much is actually myth, hype, marketting, there is so much brainwashing out there, i learn't after many many years of trying that once someones brainwashed you cannot teach them the truth as they will not listen it does not matter how much you try.

I think you need to hear your new system in the real world i.e. when you are back driving etc.
Once its been warmed up and bedded in I think you will already have a 'premium' system

Enjoy it !
