Wilson Alexia 2 lacking some bass

Very well sorted out system, congrats.  The setup guides are just starting points and the sound you hear is totally dependent on the nuances our your listening room.  Every little detail of the room matters.  Perhaps your listening position is in a node or partial node where you're getting a little bass dip.  It took me months to be fully satisfied with my speaker positioning.  Keep in mind that anything new in your system needs adequate time to run in.  Reposition your speakers or listening spot in small increments and be patient.  It would be helpful for the community to see a pic of your listening room and maybe have some other thoughts.  Good luck and cheers.

Wow, beautiful system you have assembled. All broken in? Correct? A system like that at least 500 hours… but the bass should be real close after 200. It would be of great help to see photos. You can easily post them by creating a virtual system. You can see mine. The venue is critical and it is not easy to describe fully in words.

I would say with great certainty speaker placement. It typically takes me a year to get mine optimized. When I am concerned about bass. I take off the spikes and put sliders under the speakers. Number one will be distance to wall behind and sidewalls. Once you are sure this is right… the toe in can increase the treble… tipping the overall balance.

Finally if all that leaves you a bit uninspired… is there a chance the system is a little too polite? dCs is very resrained and a bit well, not cold… but not warm.

Well, for one, all Wilson speakers are well known for having some of the best bass and dynamics in the business. So, right off the bat, we can eliminate the speakers for possibly being the issue. I have Revel Salon 2 speakers, which have the same kind of great bass that the Wilson speakers have, and wherever I position them, the bass is still there, so I don’t believe that speaker placement is the real issue here either. I believe that your lack of bass issue most likely stems from either your amplification or your cabling. All you can do now is experimentation with different cables and amps until you get the kind of bass that the speakers are capable of. Happy listening.
