See this little guy? It's the Gradient Helsinki ($8000/pair). I'm a big fan of this weird-ass speaker. Rather than placing its drive-units within a cabinet, the drive-units are laid bare, free for the world to see, mounted onto the speaker's narrow body. Why? Free love. Free love! Cabinet resonances are eliminated. The Helsinki's dipole-radiation woofer projects sound from side to side, canceling out top-to-bottom sound waves and minimizing deleterious room reflections.
