My Evora is a MY2011 S model with full options (factory car) equipped with Alpine IVA-W520R, fixed navigation module (not the IVA-W505R using blackbird), bluetooth module and factory fitted IMPRINT PXA-H100 module.
I didn't notice any difference between "CURVE1" and "CURVE2" on the IMPRINT system, so I decided to buy the Alpine KTX-H100 to measure myself the sound and do my personal curves.
Here is the Imprint module behind the dashboard:
For people who would install Imprint themselves, the "X-OVER" switch is set on "FRONT/REAR/SUB W." and not on "3 WAY" as the 4 front speakers on the Evora are drive with the front line of the head unit.
So the rear RCA outputs of the Imprint module are not connected (as seen on the 1st picture), the front RCA outputs goes back to the head unit and the sub RCA outputs goes to the rear sub amplifier.
It's very easy to connect the microphone and the usb cable and do your own curves. The software tells you to put the mic on different places on the car.
At the end of the process, you can choose between 3 curves :
-reference (with a little more high frequencies)
-reference with mid-range compensation (like reference with a little more voices frequencies I think)
As you can only save 2 ones, I choose these :
The result is awesome, the 2 curves are really different and I can now hear the sub very clearly.
When Imprint is on and one curve is selected, you can still access to the treble/bass level, the sub level, and the balance/fader.
My preference settings are :
- reference curve
- treble : +0
- bass : +3
- sub : max (+15 I think)
- fader : 3/5 to the rear : when you put the fader to the rear, the sub stays to the same level and it attenuates the main speakers, so it reenforces the sub...
Hope this can help, the KTW-H100 is very cheap and does a very good job!
Sorry if there are some langage mistake, I live in France and learned english at school...
