Digital room correction

USD 500 for Lyngdorf's RoomPerfect system! Now we're getting somewhere! 

Let's see if it is available for a demo here in Belgium...

Cheers, Bill 

Another option, not sure of the cost:

John Atkinson was clearly impressed by this system. Worth checking out.

It does involve an extra analogue --> digital --> analogue conversion, though...

Keep 'em coming, guys! 

I was having a chat with one of the guys from JL Audio about various things. Asked him about his opinion on the DSPeaker Antimode & he was fairly enthusiastic about the unit. But felt that the DEQX was a much better proposition.

Room equalisation wizard  is an excellent free software package. Along with good graphics and measurements, it will produce FIR files in a format that many dsp equalisation boxes can use. Just google it to get to the download page.

For hardware, there is a great group out of Hong Kong producing some innovative products. Google 'minidsp' and have a look. My son is building a pair of active speakers using dsp crossovers and class d amps based on their products.

Thanks Bill.

Those prices are for the HDP-4 & express which are a pre-amp with the room correction function built in.

The link I originally posted was for the DEQX-Mate which is the room processing only, no pre-amp as such. You would have to think that it should be cheaper given it stripped back feature set?

You can also use your PC as a "stand-alone automated digital room correction device" (see Auto EQ at http://mathaudio.com).

Hi Mix, and thanks for your suggestion. (welcome to the forum, btw!)

I followed the link you provided. If this works well, it's a dead bargain! But I don't see how it works exactly. The software is run on a pc and gets its input through a microphone? How does it change the sound of the hifi system then? Where does it get into the chain?

Do you use the program yourself? If so, what's your impression?

Just found two US sites, where the price of the DEQX Mate is set at $4500 ( ). I contacted DEQX to ask for a Belgian dealer (and price), but got no response yet.

Another option mentioned on one of the sites is Trinnov, a French company (never heard of them...). Not a clue on the price.

Confirmed by DEQX's Alan Langford: The retail price of the MATE processor is US $4495.00 plus any local duty and taxes.

And no dealer for Belgium...

10 years ago, the innovative product design was done in Mountain View, CA.  Sean Adams and Slimdevices were already pushing streaming solutions, many manufacturers have still to catch up.  The squeezebox range all allowed for digital room correction via a plug-in (Inguz) which pre-processed the audio bitsteam on the fly at the server before sending to the streamer. Parametric equalisation, finite impulse response filter support - for free!

I firmly believe that the torch is being passed to China.  As I posted earlier, Minidsp (I am not connected in any way) are producing highly innovative product at very competitive prices from Hong Kong.

A quick glance at their products would indicate that their range is significantly more powerful than DEQX at what appears to be 1/10 of the price.

I haven't used their processor, but their multi channel dsp crossover and poweramp is great.

I had a look at their site, and one more now, and I must admit that I cannot comprehend it completely. The reviews they link to seem te confirm that you need a decent technical background to go to work with it (background which I'm lacking obviously ).

You're not alone... took a look myself and was quite lost!

If I were to still be after a solution, I think I would settle on the Antimode.
