Anything new with digital room correction?

Shadorne, I do not have the sub.
My speakers are PMC IB2, two channel.
Humps are 50Hz on left channel and 40Hz and 70Hz on right channel, quite severe, somewhere around 8dB.
BTW, I drove to States to hear active ATC50s, setup was not that great (they did not get them stable enough on the spikes, they were somewhat wobbly), quite similar to PMC as far as midrange goes (which I could never give up), but overall I have not heard any reason to switch, so I am sticking to PMCs, seems I will be buried with them.

PMC used ATC midrange in the past. PMC are absolutely excellent speakers. I think they use Volts on the woofers but the design is similar to ATC but with more bass (TL design). If you already own PMC then I am not surprised you heard no reason to change. ATC probably have the edge with classical listeners and PMC probably has the edge with rock (more bass) but it is indeed a close call and at the end of the day a matter of taste. I'd probably be just as happy with PMC.

That is actually not bad at all, IMHO. If you tried to hammer that all flat then I am not surprised that it might not pass for an improvement. Of course, the nulls are the worst....as certain bass notes just disappear.

Yes, I have a couple of nulls above 100Hz, but not exceeding 3-4dB.
I bought 22kg of lead shot today, will try to play with mass on speakers and stands, as well as some further attempts at room treatment with homemade stuff.

Rives-

Your post makes it sound like Sashav and others would need new equipment which is totally false. Almost every high end CD player allows the D/A conversion to be bypassed so no one has to buy new equipment to use the Lyngdorf room correction equipment. This is no more complicated than using a digital out from your CD player which is usually toslink or digital RCA and occassionally XLR.
