if we're talking corner placement and balanced sound..gradient for sure. out of the corners, any full range sealed design that doesn't favor certain frequencies would owe a bit (directly or indirectly) to roy, henry kloss, and other AR alumni.
Is there a modern equivalent of Allison Ones?
I have a 30 year-old refurbished pair of Allison 3's, placed in the corners of my study. They are fantastic in terms of ease of placement (:):), take up no room, disapppear sonically, soundstage and project well, and are extremely musical. But they don't have the resolution or clarity in the highs and mid-range that the modern speakers do. I am looking for speakers that can be placed against a rear wall, like the Allison One's, for another room, but with the modern improvement in resolution and clarity. Are there any such speakers? Are there any floor-standers that are made to be placed against the rear wall?
