It's only the second week in January and I've already found one of my top picks for 2009 – the Wisdom Audio Sage Series L150i Architectural Loudspeakers. The Wisdom L150i is a line source in-wall speaker system that stands at 76-inches tall and is large enough to be the wall. Each channel consists of 12 six-inch woofers and planar magnetic line source drivers. The woofers and planar drivers are housed in separate aluminum back box enclosures and Wisdom recommends that the drywall be replaced with plywood or MDF for greater rigidity. The system requires a Wisdom electronic crossover and must be bi-amplified.

I heard the L150i in a multichannel system with other models from the Sage series for the center and rear channels. Oustanding transparency, detail and depth are just a few of the adjectives I would use to describe them. The Wisdom Audio Sage L150i is $15,000 per channel and the electronic crossover is $6000. I'll consider them when my 201k becomes a 401k again.
