I thought the Xd system included it's own amp, a digital amp with EQ.
The beauty of the Xd system is in it's integration of
Sats, Subs, Amps and EQ, and of course good looks

You're going to have to add some shelving eq in the DCX2496 to deal with the drooping woofer response from the very small baffle. Here is an ok writeup on what that is:

Without this eq, the speaker is going to sound very bright. You don't really even need acoustic measurements to do a decent job of estimating the needed eq. Just use a high shelf filter with 6dB of cut and a cutoff frequency of about 800Hz. That will make the speaker sound much better.

True.
Except that I have not been able to find one.

[edit]
Thinking further about it, I am finding some advantages not going XdA.
So, not being able to find one might be a good thing after all.

The XdA introduces an extra digital->analog->digital step that my current setup does not.
Further, it also puts volume control before the XO whereas my current setup puts it after the XO and EQ.
Last, the DCX2496 is more generic with support for EQ and dynamic EQ, which is all you need (with a bit of knowledge and information).
I am not convinced that the benefits of Powerphysics amplification makes up for the issues stated above.

I guess this better explains the slight brightness I had noted and the apparent dip in the mid-bass.

Since the RTi10 are closer to the wall, I assume room measurements will show a dip from 150hz to 700hz.

For the high shelf filter, are you proposing a 6dB slope or a 12dB one?

Thanks.

[Edit]
Okay, I just did a -6dB gain with a 6dB slope high shelf filter @ 805hz.
Wow! What a shift from slight brightness to total warmness!
The mid-bass dip has also been greatly attenuated.
My blues and Neo-soul albums thank you.

I am certainly not going to use this setting for all my albums, but this is one setting I am saving as a preset.
I can't wait to start doing some in room measurements and coming up with different presets.

Yeah, I tried both and the 6dB slope was right on.

Thanks.

What you are missing is something that cannot be captured with a camera.
The speakers have a color shift that has to be seen in person.

I might take a HD video and post it when I get a chance.
