Now it is clear. The box right behind the speaker is the size of the original crossover and you can see the speaker cables coming in, so no changes there. The other box that was in question is a new enclosure and look of the Elysian sub amplifier. He made the level controls on that unit more of a match to the main speaker look. It looks like more sound absorption panels and plants than in the past.
Some words from another reviewer. Living Voice’s Vox Olympian horns. Unfortunately only got to listen to classical music here. The room was full and I was lucky to get a spot right smack in the sweet spot. Sometimes you feel a system before your brain can rationalize the sound. Not talking about deep bass. I felt an instant calm and relaxation wash over me. The only other time I felt like this was when listening to the top of the line audio digital stack some years ago. In a word: THIS was music nothing more nothing less. Forget about detail, driver integration, sound staging, on any other term used to describe hifi. This was the least hifi I’ve ever heard a stereo sound. Even the term stereo doesn’t apply here. One could call this transcendental. I don’t want to get lost in superlatives, but this is without a doubt the most musically ENGAGING and REAL sound I’ve ever heard!
