Room correction - what device works best?

Its still too bad the DEQX requires the movement of the speakers and consultation to obtain best results.

My current speakers weigh 215lb each and have spiked feet.

Perhaps sometime in the not too distant future there will be a more user friendlier version.

In the meantime, I'll stay on the sidelines awaiting Almarg's adventure.

Kal, or anyone else who may know, how does the speaker correction of Dirac compare to DEQX?

There's a subtle difference between room and speaker correction.

Room correction you put the mic at the listening seat and you measure speaker and room combined.

Dirac only offers room correction (though a very good algorithm, and one I really like).

The DEQX separates out speaker and room correction into separate processes.

The speaker correction is done by measuring the speaker nearfield and windowing out the room response (or measuring outside). Then you take the mic and put it in the listening position like you would do with Dirac.

Not sure when people refer to Dirac if they are referring to the software package or a hardware unit with Dirac inside? Either way I understand it can't do crossovers. In case someone meant software, then Acourate can do digital crossovers, driver linearization, time alignment and room correction.

There was a comment above indicating frustration that DEQX could only handle 96kHz, and a great reply by Almarg. I completely agree with Al. To add my experience from another angle: at some point I was considering the 8-channel DAC e28 from exaSound, which can play 24/192 & DSD256 natively on 8-channels. It looked ideal for my needs. Discussing this with Uli Brueggemann from Acourate, he explained he tried it at 24/96 and a powerfull computer was running out of steam, suggesting 24/192 would be very very hard. So I dropped the idea, despite my computer being very powerful (server motherboard with Xeon processor, etc).

Acousticfrontiers,

Can you explain what the benefits are from separating room and speakers into 2 distinct steps? From what I can tell from the Dirac website, they are also doing some speaker correction, which appears to be from the listening position in the listening room.

Thanks for your helpful clarifications.
