Marten makes some monster loudspeakers, this is known. The newest offering in their top-of-their-line Coltrane lineup is the Coltrane Tenor, and like the rest of the loudspeakers in this line, it is replete with — one might say festooned with — drivers from Accuton. A diamond driver tops the cabinet, a top-drawer Accuton mid-range, and two brand-new aluminum-sandwich convex drivers (they’re outies, and yes, they stick out, not in) down low. A carbon-fiber/wood cabinet with traditional Marten fascia rounds out the package.

Shown here with electronics from Nagra, the sound wasn’t … exactly … top drawer and I couldn’t help but think that these loudspeakers were being held back. Maybe. Either that, or the drivers weren’t broken in, which seems likely as the bass response wasn’t overpowering the room — and it probably should have, if that makes sense. Whatever the issue, those new bass drivers are odd-looking, like someone took an Accuton driver, with grill still on it, and laminated over top of the grill. Like I said. It’s weird. Very pretty, though.
