Audiolense with an AVR (Denon X3800H)

If the bass management is implemented in the Denon unit, you probably have to settle for a 2.0 correction and measurement. This means that Audiolense will not see the subs as separate entities, but if the integration done by the Denon is reasonable in face you will get a very good result nevertheless. It is more or less the same as doing a global speaker correction without using digital crossovers.

You can only do that if the receiver has a mulitichannel input connected to a multichannel output from your PC.

Nevertheless Audiolense should give you a seamless subwoofer integration even if it doesn't see the sub as a separate entity.

Yes, you get the time domain correction and more tweakability which literally always sounds clearly better ... more transparency and more air between the tones, better decoupling from the room and better sound stage. The TTD correction introduces a few hundred milliseconds of audio latency. This is not a problem for music, but can usually not be used for TV and video material, due to lipsync problems.

Apart from that, quite often the partial correction offers improvements in the top as well. Al xo is a more tweakable solution that enables a more optimised correction tailormade to your system and preferences.

There are two ways to try it out.

1) Remove the license file temporary and use the demo and listen to 90 seconds' passages of corrected music.
2) You can purchase the upgrade... and then downgrade back against a full refund if you decide it wasn't worth the. This option is used frequently, but I rarelly get downgrade requests ... the sound quality is clearly better.
