Remember the $250k Marten Coltrane Supreme speakers adorned with diamonds? Here are their new little siblings, the Coltrene Alto speakers reviewed by 6Moons. Of course, without all the ice and the dozens of drivers per side, price is down to a bargain $24k. Interesting features include an usual downward firing woofer at the bottom of the carbon fiber box. Sound?
With the exception of the big Coltranes in terms of integration of bass and lower bass with the rest of the spectrum, this is the best I've come across.
Good to know not much is lost between the $250k Supremes, the garden variety $50k Contrane and the $24k Altos.
