Wilson Alexia 2 lacking some bass

Hello everyone,

I’m reaching out for advice on fine-tuning my system, as I'm noticing a minor lack of low-end response that seems unusual given the capabilities of my speakers.

Here’s the current setup:

  • Speakers: Wilson Alexia 2, positioned on spikes per the WASP guide
  • Amplification: Nagra HD mono amps
  • Digital Source: DCS Rossini Apex with DCS Rossini Clock
  • Server: Antipodes Oladra
  • Cabling: Shunyata Omega throughout
  • Room Dimensions: Approximately 20 x 15 ft

I’m wondering if the amps may not be the ideal match or if further adjustments to the speaker placement could help resolve this. Any insights would be greatly appreciated.

Thanks in advance

Great system.  Maybe the Alexa’s are to far from the front wall?.

Just a thought.

@greenspyder718, does the minor low-end lack you describe show up throughout the room, or only in the listening position? 

Is your 20 x 15 foot room open into any other rooms?

Can you describe approximately where the speakers are relative to the nearby walls? 

Thanks!

I owned Alexia2 for almost one year and just traded in for AlexiaV this week. In my experience Wilsons are never lack of bass response (not sure you meant 40hz deep bass or 80-100hz mid bass, and not sure you meant lack of bass volume or dynamics ?)  also how large is your listening area that the amp+speakers can fill with enough power ? 

I would try to move the speakers 1/4inch at a time, towards the front wall and see if it helps. Another thing I tried is to take away the grilles of bass drivers and it should give you 5% more dynamics or punch feel. 
 

I am not familiar with the preamp you are using , but another way to try is to adjust the gain on your preamp and see if that helps.

I would add 2 Rel subwoofers like the S 510 or the S 812. I just added 2x S 500 with my Shindo Masseto and Montille amp and Fleetwood Deville SQ. Wish did it before, it is really a match made in heaven. Perfect bass , better coherence and live sounding.You won’t regret it, believe me, will take your system to another level.
