Long awaited Smyth SVS Realiser NOW AVAILABLE FOR PURCHASE - Page 185

post #2761 of 2763

As I posted before, anyone who owns some SE535s is welcome to try my SE535 HPEQ file and judge for themselves. :)

 

However:

 

- It is not straightforward to create HPEQ files using Blu-Tac. You need to do it carefully and may need several tries. I created several different HPEQ files with Blu-Tac (with a slightly different seal each time) and compared them to each other to judge which one was the best. I played the front speaker only, as that is the most difficult to 'virtualise' in my experience, and picked the HPEQ file which sounded the most 'outside my head.'

 

- Any HPEQ file created without Blu-Tac (or some other way of creating a seal) is useless, in my experience.

I have a question regarding the HPEQ-optimisation. In the manual it says at first:

 

...

For this compensation, the Realiser generates a filter which is the inverse of the measured response.
However, a complete inversion may be neither possible nor advisable, if, for example, there are anomalies that are large and the compensating inversions would cause overload or signal-to-noise issues.
Therefore the Realiser typically compresses the inversion.
...
 
and a little bit later it states
 
...
1.0
denoting a full inversion of the
measured response.
...

 

So does this setting mean the device let me do a "neither possible nor advisable" inversion or is it related to the maximum compression of the measured response? So if I set the inversion to 1 it would apply the maximum inversion which is possible without having issues regarding overload or signal-to-noise issues or it would ignore this issues and there may be some degrade in sound quality of the measured PRIR and possible overload/distortion problems?

 

My problem is that i have new super comfortable headphones, but the combination of the prir and headphone characteristics give me some shrillness on hot recordings. So i try to improve the treble response with different inversion settings. Is this the right way?

Just try what sounds best. Nobody else than Smyth knows how _exactly_ the inversion works.

It's clear HPEQ is not perfect, HD800 6khz peak makes it go crazy unless you lower the middle value.
