Digital Room Correction For Speakers

I agree with soix recommendations. I thought of changing speakers myself after trying room treatments that did little to correct my bass problems. I also tried putting the supplied port plugs in my speakers that helped a little but I did not like the overall sound with them in place.
The DSPeaker 2.0 Dual Core was a major improvement over everything else I tried.

I wouldnt mess with EQ. If you have room modes you can solve this by adding mass to the room. An example would be to get concrete forms and fill them with sand. Books or albums can also help. Find a room mode calculator to see where your problem areas lie and then fix it in a way that will not detract from your sound. 

Any room EQ can fix some problems but might degrade the sound on other areas because every component that implement equaliser manipulate the sound and harm the original recording .You should be very careful once you decide to buy room EQ it's better to check it in your system and in your room what is exactly its affect on the sound and if you like it or not.

Please take a moment to research how these EQs work and then ask yourself if this method sounds like something that makes sense and will not degrade your sound. Look in detail at how these EQs address the offending frequencies from the ones that dont have problems and how subsequent changes are made. A bit of research and a small amount of money will fix the problems permanently and without any downside. I think that the problem is not the equipment but how the equipment interacts with the room. 

I use a DSPeaker X4 in my system but only for the subs without any interference above 79Hz where it is crossed over. I simply wanted the best bass correction solution without interfering with the pristine signal to my main speakers from my own DAC regardless of cost. The X4 has done a stellar job, my bass has never been better. My DAC is an EMM DA2 and my preamp a Merrill Audio Christine. I did not want to interfere at all with the signal coming from these amazing components and going to my Pipedream speakers, so I run a second full signal to the X4 from the second output on the preamp (luckily Merrill Audio Christine has two outputs available!). The DSPeaker X4 allows a million adjustments, and I let it pick the crossover (79Hz) and had some golden-eared friends (thank you Merrill from Merrill Audio and Larry from Distinctive Stereo!) make the fine adjustments. So now I have 2 full signals going from the preamp to two sets of amps, one to the Pipedream's amps untouched by the X4 and it's DAC and the other full signal to the X4 for processing and then on to the subwoofer amps. It's perfect.
