Digital Room Correction For Speakers

The Anti-mode 2.0 can. Surely also the X4. But the 2.0 has enough possibilities to make you occupied until summer! What the 2.0 miss and the X4 has is a xo bass management system. I use a Lyngdorf RP-1 or 2200 amp for this. 

Can the DSpeaker X4, be used strictly for room equalization and not as a preamp or dac?

One thing I believe is that active room correction actually means different speakers can compete in the same room on a more even basis. You hear that the difference between speakers after correction is actually less than before, which means the room interaction on different speaker accounts for the main difference in sound. You can now concentrate on dynamics, resolution, tonal qualities, edgeness etc that is left.

There´s also Trinnov in that price range.

Thanks for the great review. I need to look into this system.

1) Treatment, which you already have.  
  
2) Mutliple subs, either through Geddes’ approach or the standard symmetrical one. 
 
3) EQ. If wanting to use it also as your DAC/pre-amp, the MiniDSP SHD with DIRAC is high enough in quality where it can be considered audibly transparent. 
 
You should always take multiple measurements, but 90% should be around the main listening position, with some spurious measurements in other seating areas (which aren’t close to a side/rear wall).

Thanks for the tip on X4. I use the Anti-Mode 2.0 with very good results. Arc2 also make wonders for my desk-top systems. Older Lyngdorf makes too much bass in my opinion but have usable standard eq curves. The new Lyngdorf amp 3400 as Anti-Mode offer in addition to automatic dsd also manual settings which you need. Will soon start to use Dirac Live. Lots of audiophiles unnecessarily afraid of active room correction. Just measure you room and be shooked :-) Naturally you should do what you can with your room and listening position in the first. Mickey Mouse - why? Not very proffessional. We all know there are more expensive and even better products.

I tried bass traps and room treatment which helped the sound overall but did almost nothing to help my 2 problem areas, one around 50 hz and another around 110 hz. I bought a used DSPeaker Anti-Mode 2.0 Dual Core here on Audiogon and it worked wonders at a reasonable price.
The X4 mentioned earlier is an even better option but cost substantially more. Good luck!

Lyngdorfperiod. Rest of this stuff is Mickey Mouse. There are a couple much more expensive products out there too.

Everything you can do to improve the acoustics of the room is what you should do first.

On top of that, well implemented digital room correction can be outstanding. I started down that path, then went 4 channels to add stereo subs, and now 6 ways to have the midbass in the towers on separate channels. 

How is your system configured? What source/s do you use?

Any high end pre-pro (Marantz Onkyo, NAD Maaster, McIntosh, etc) equipped with Audyssey will work beautifully.   

Legacy Wavelet which at full use is a DAC, pre-amp and RoomEQ is an outstanding example.  It can also be utilized only as a RoomEQ device with your own DAC and Pre-amp in front of it.  I've used it twice now with 2 generations of Legacy speakers with great results.  I have heard that Bill is starting to open up its use (or will) to pair with other speakers. Best to talk to Legacy direct about this and see where they are with this.

The Vandersteen 11-band EQ only effects frequencies below 100 Hz. Knocking down the big bass humps really improves midrange transparency, though. They just added a subwoofer to their line, the Sub 3, with the 11-band EQ, so you can add this to any speakers now.

I’ve been using the free DRC-FIR software for digital room correction with excellent results. I use Room EQ Wizard and a Umik-1 USB mic for the room response measurements. DRC-FIR produces a filter file from the room measurements that can be used with a convolution engine in a digital music server like Roon or JRiver (I use the Logitech Media Server BrutefirDRC plugin).

If you have bass nulls in your listening position, no amount of room correction can make it any better.  All room correction can do is tame any excess bass response from the room.

If you have more than a 6~ dB null at any given frequency, and you try to lift that, you will only destroy your speakers and get little to no more bass.  They’ll only be working harder.

Minidsp 2 channel units like the DDRC22D or the surround units like the NanoAVR DL are quite easy to use and Dirac Live is currently the most advanced room correction available.

When I couldn’t get decent bass from my revel salon2’s I knew my room was a stinker and the experts said the only solution was multiple subs to eliminate the nulls. What about ARC? 

I gave up on conventional speakers and bought a pair of DSP8000’s and it works so digital room correction should work for you 

The problem with this approach is the best it can do is flatten response at one location. But this comes at the cost of worse response at other locations. Not to mention all the problems inherent in equalization itself.

By far the better approach is to take whatever money you're thinking of spending on EQ and treat the room and speakers with HFTs. 

I recommend Dirac Live. It's available in various products, as standalone computer software, and the most cost effective and flexible solution tends to be the miniDSP products. The newer SHD series can also be used to precisely integrate subwoofers, routing, and provide active crossover functionality.

Bass builds up in corners especially near the ceiling.Did you try the traps straddling the corners behind the speakers?Prop them up on the back of a dining room chair to get them up higher and see what you think.

steve59 if you can let us know which direction they go with your treatments.

I have installed GIK monster bass traps behind my speakers and audio rack and still have too much mid bass. Even went to the trouble of blocking the bass ports with foam.

In the price range we're playing any speaker is going to need room treatments and anyone with experience will tell you the least amount of electronic room correction needed the better the results will be. I'm in the same boat as you(or similar) with a room that has too much support in the mid bass region and not enough in the low bass. I'm working with a shop to balance thinks out with treatments.

It will smooth frequency response anywhere it detects an issue. So what are you trying to accomplish? Have you tried any acoustic treatments first.

I do not use any subs. Will Speaker X4 still work?

I use Dspeaker X4. Easy to use and awesome for sub integration if you run subs.
