Concrete Audio Speakers...Speaker Enclosures made out of Concrete ?..

I was an electrostat listener for over 20 years, from Acoustat Xs, 2+2s, Martin Logan Monolith IIIs (and reQuest for 2nd system).  Then I met my wife 23 years ago and she found them unlistenable.  She said they lack dynamics, bass and more than one listener ability.  She was right.  I went to big dynamic box speakers which had all of those factors.  The best speakers I've ever heard or wanted are large dynamic box speakers (except for maybe the big SoundLabs).  I should have kept the 2+2s for my second system.  Can I suppose that your listening to electrostats is for yourself primarily and not for a group of people?   Sanders stats are particularly one person speakers, like giant headphones.
