DSPeaker Anti Mode 2.0 evaluation

I have read all of the glowing reviews of this product and I just don't understand why I am not impressed. I have been lucky to find a very kind dealer to allow me to try one the DSPeaker Anti Mode 2.0 units.
I have 2 JL Audio F113 subwoofers that I have set up in stereo and are based on their own microphones measurement calibration.

So, with those sub settings and then switching out the LF Filter, I then used the DSPeaker unit to eq just my JL subs. That is, I tested the unit by playing my Andra 2 speakers full range via my Pass Labs Preamp and Amp and with the other Preamp outputs I plugged in the DSPeaker in and then the JL subs are plugged into the DSPeaker.

I ran the DSPeaker calibration. I used the DSPeaker in and out of the flow by using its bypass button and I really couldn’t tell much of any improvement. In fact I believe I like the bypass sound better.

Why is this? All of the glowing reviews and it is only marginal different if at all.

Now, there is an update for the DSPeaker in June 2013 but my Norton Virus control will not allow the download. Perhaps, if I was able to download that update it would be better, but I doubt it.

So, before I end my trial of the unit, is my configuration flawed , what do you guys think?

All such products diminish absolute definition/clarity - no exceptions. They must, as they are not necessary devices inserted into the signal path. It is to be expected that the system will sound cleaner without any non-necessary device inserted.

This is not to say that such devices cannot confer a pleasing quality, and some people may like it better. But do not expect superior cleanness when inserting a non-necessary device into an existing rig.

Douglas_schroeder, I somewhat agree with you. That's why I am only using the unit on my Subwoofers.

Ozzy, you may even consider the physical placement of the subs; I use Legacy Audio XTREME HD Subs following the review at Dagogo.com, however I use them backwards. They are normally backwards firing, but I feel the sound is far superior when they are turned around and the primary driver is firing forward. I also placed them on hockey pucks to elevate the downward firing passive radiator. I discuss this in the review.

Such experimentation can have a nice improvement in store, and you may be able to get both improved definition and bass response.

Douglas_schroeder, Thanks for the help. I'm using 2 of the JL Audio Fathom F113 and they are forward firing.

But, I have never tried footers on the subs. I do have some Black diamond that I can try. But the subs are heavy...

Douglas_schroeder,

Have you heard the device in question?

Maybe Kr4 can comment on your statement "All such products diminish absolute definition/clarity - no exceptions," which is a bit too absolutist and sweeping for my taste. Not to say that it might not be true. Good thing multiple retailers of the DSPeaker have audition or return policies.

IIRC, at least one of the published reviews of the Dual Core made reference to the transparency when it was in the system. Greene's TAS review I think?
