What can I do to improve my 2nd system?

@russ69 Thank you for the clarification

@erik_squires I was thinking about "upgrading" to the SVS SB 1000 "Pro" version that has the 3-band EQ feature at a trade-off of losing HPF capability.  Later I learned I could add an in-line HPF on the loop back to power amp but had a worry on the quality of in-line filter.  It is a trade-off.  The other option will be the miniDSP that you have alluded before on the other tread.  I need to give it a bit more thought.

Here comes with an interesting suggestion you have "crossing the speakers in front of you..."  To be frank, I have never thought about that.  The most toe-in I have attempted or suggested from other sources is pointing to the listener's position.  The laterally reflected indirect sound is reduced but the speakers become too bright on my face from these Elac bookshelf.  So I gradually reset it back and finally dialed in this slight toe-in angle.  Without the absorption treatment, I actually experienced a bit more spacious sound stage (believe or not).  I read about the "Sound Reproduction: The Acoustics and Psychoacoustics of Loudspeakers and Rooms" book by Floyd Toole.  He actually pointed out that some people actually like stronger lateral reflection because of the augmented sound stage and I think that might be the effect I was experiencing with.

Nevertheless, "crossing in front of the listener" is definitely something new and I will try that...

Well, saying you need DSP EQ is kind of an oversimplification of measuring first, then treating, but the miniDSP units are very capable especially for subs.  I would keep your sub and enhance with it.

Speakers vary by a great deal on what their ideal toe-in is.  Focals for instance, to me sound best with zero to just a little toe-in.  You can see in the measurements with some speakers that on axis they may have big peaks and valleys which get a lot smoother off axis.  Toole was also probably thinking of less constrained rooms.  Anyway, it's a total judgement call so try it and let me know if that's a good choice for you.  As a long term solution though consider the GIK acoustics bass traps with diffusor panels.  They will give you a sense of air and space while helping to focus the image and reduce bass standing waves.

OH, also, try listening BELOW the tweeter axis. :) I find this sometimes more pleasant. There’s nothing wrong with that either.  I ended up using Isoacoustics speaker stands which let me tilt the speakers up.

Best,

Erik

Hi, Erik, I will try those excellent suggestions after I get home and embark on the miniDSP journey including room measurements.  I like out-of-the-box thinking and approach doing things.  Also thank you all gentlemen for the advises. 

Doesn't the Parasound need more space for air flow?
