“The Rubies will play unreasonably loud for their size…It might surprise you to learn however that Ruby’s midrange is warmer and fuller…Bass is shocking, period. There’s still life at 30Hz, rolled off naturally but sufficient present to mix in and support a very robust midbass. That’s simply otherworldly for a speaker this size. Unbelievable in fact.

So, this isn’t a laid-back but intense speaker. Intense in a good colorful way, with kicking-boxing jump factor and completely counter-intensive fullness… In short, absolutely perfect for what I wanted.”
