Hi all!

I'm looking for some pointers on how I might improve the results I'm getting with Dirac.

My speakers are a pair of self-made full range rear-loaded horns (Frugal-Horn XL). They work quite wonderfully, but really benefit from some EQ correction, as the bass is a bit boomy and the overall sound is a bit nasal, with the lack of a better word. On the other hand, the space of sound they create is unlike anything I have experienced in a stereo system. It really feels like the music is all around me to the extent that on some recordings this can be even a bit distracting.

Anyway, using Dirac has worked wonderfully in correcting the bass, it is much cleaner and tighter after the correction. The midrange imbalance is also eliminated. You can hear more nuances.

However, what also happens is that feeling of space is almost completely eliminated. With the remote it is easy to toggle the filter ON and OFF, and while the sound objectively gets better when the filter gets turned on, it also effectively sucks the sound out of the room around me and places it neatly between the speakers. Some folks might disagree with me, but I feel like I'm almost losing more than I'm gaining.

Is it possible to achieve a corrected response without taking away the sense of space? I would think that microphone placement might be the key here, but I wanted to ask for some guidance before starting to randomly experiment. The way I performed the measurements now was with the 17-point regime, sofa setting with wide imaging. I pointed the microphone towards the ceiling.

Any advice will be greatly appreciated!

You could perhaps try limiting the correction frequency range and see if that makes a difference?

I wonder if the 'loss' in envelopment is due to some resonance being removed from the room - what does the initial curve look like before correction? post up a photo.
