If the QP85 is like an ice crystal, the PMB100 is like flowing lava. For me the QP85 sounded good right away, while I didn't like the PMB100 at all at first-- but in the end it's the 100 that feels indispensable, for me. It has a lot to do with the way it handles voices. For general use, the 85 is the better option. The Silvertone barely deserves to be called a Jecklin; it's overdamped to the point of ruining the soundstage and has inferior drivers to begin with.
In both cases, though, the bass-canceling backwave (due to the 'completely open' design) is a nuisance-- the drivers are producing great bass, but it doesn't all reach the ear. You can hear it if you block the baffle with tape, but it will ruin the soundstage. Theoretically some thinnish felt damping applied either behind the driver or flat behind the baffle should fix the bass without too much soundstage degradation. It's a pretty easy frame for potential modding, like working on the engine of a seventies truck-- plenty of room to see what you're doing.
Did someone ask for details on the stats? Sorry, can't find the bias voltage listing. But I do have this, courtesy of MB's Willi Pressuti:
