Digital Room Correction For Speakers

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!

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.
