Basic gramophone question…

[john-e89]

Time to upgrade the ‘Business’…what a stupid name… :lol: radio in the 35i. I’m thinking it being the basic offering is a good thing as with no factory amp hopefully I can just add a DSP and a couple of meaty amps, two underseat subs, Focal mids and tweets with all new quality wiring run straight from the amps bypassing the standard wiring, without the usual issues with the factory amp etc. is this feasible…?

Ta muchly…

Could you not just ask Peter via PM? Saves another one of his expert monologues on all things sound related with the e89! oke: :rofl:

That Z3-rrari isn’t getting done with you gassing on here is it Pondlington…. oke: :wink:

No but I've got some spare BMW-spec speakers if you want them...

You mean those rice paper dome standard ones…? Thanks but…. :lol:

Thanks but….

Ungrateful bar-steward.

You do realise Peter probably won't respond now, and TBF he IS the best to answer your questions judging by the £40k he has spent on his 'sounds', all so he can listen to Des O'Connor in full surround sound at 300db! :rofl:

Yes pretty straightforward…the headunit needs to be coded for Hi-fi as opposed to whatever it’s called as the 2 rear channels are badly tailored frequency slope ..

Otherwise fine..

Enjoy

Quite a few people now do harness adapters for this basic version …

Thanks for the clarification Peter, appreciate that, as well as the coding point.

These guys are pretty good and know E89s..couple of Scottish lads have used them very successfully..

I've done just this, changed all speakers added two amps and two subs in the panel behind the rear seats as well as a MMI box and I did not code anything and it all works very well. Here's the thread:

https://z4-forum.com/forum/viewtopic.php?t=126024&hilit=another+6+speaker

Should mention, regarding fitting underseat subs. I don't think there is enough space under the seats to put anything.

By default the 6 speaker system has a high end roll off filter on the back 2 channels..which unless you code it or have a very fancy reverse filter processor will mean they continue to have high end roll off..FWIW

What’s high end roll off?

You get this…

A really crap frequency response …in a desperate bid to try and get something out of the shite speakers and address various issues the signal is very heavily processed..the same but to a lesser extent happens on the front..on 676/677 set ups the headunit is set to hi-fi aka flat as any tailoring / processing is done in the amp not the head unit..

So FWIW any set up using the basic head without coding is really an amplified abomination :tumbleweed: :rofl:

This might be but to my non audiophile and poor quality ears I can’t tell the difference and it sounds great to me! :rofl:

But seriously I’ve had people in my car and all have commented how great the system sounds, but then again none of them are audiophiles either.

Been many tests where people have been played massively adulterated music but because it’s got certain attributes like lots of treble or bass it’s perceived as great..at the end of the day if you’re happy that’s all that matters..

To me seems crazy to spend good money on decent gear and not have it set up right..

I’m merely pointing out the facts..let that never get in the way of a Forum opinion..

Maybe true but my setup cost me in the low hundreds rather than thousands, I guess if I was spending big money then yes it makes sense to do it. I think though for most people looking to get something better than the really poor factory setup, my rather simple upgrade would suffice.

I think you may be missing Peter's reasons. :wink:

Now, Now people

I get the point on spending lots of money, and in doing so it might as well be set up properly... BUT at the end of the day this is a car, and a convertible at that, the general all round noise (road, wind etc) somewhat defeats this, especially when the roof is down.
Saying that though I wasn't aware of that coding in the 676 would change the properties of the rear 1/4 speakers. Following a post (somewhere, I can no longer find it) where I'd mentioned about adding the tweeters into my own 6 speaker set up, it was suggested that I should code in 676 for a better tweeter response. I did this but, as it wasn't the amplified system with the subwoofers, it sounded "tinny" so I uncoded that and returned it to how it was, which is a nice all round sounding system. Now when I retrofit the business system (14 speakers) it will be coded again for 676, and in so doing I expect that it'll sound correct this time as I'll have the rear subwoofers. So I'll see then what difference I get from the rear 1/4 midrange ones, along with their added tweeters (hence it being 14 speakers and not 12!).

The price is not the issue..for sure a £200 speaker will sound marginally better than a £50 speaker but to come to the point that John E89 was asking..that is he’s going to spend at least a modicum of money in his solution..in that context he deserves to have as best a set of signal sources that it can muster..garbage in garbage out…

Nothing wrong with the Scottish/American mid 90's rock group. Should sound very good with some decent bass :driving:
