The new Stealth Architectural series of in-wall and in-ceiling speakers is like a child in reverse - it's there to be heard and not seen.  Speakers in the line boast rigid poly cone woofers and Folded Motion tweeters and have been voice-matched to the Motion Series.

MartinLogan says that the key to the sound of their new speakers is an advanced topology crossover network that boasts polypropylene and low-DF electrolytic capacitators, custom wound inductors and both thermal and current protection.

The Stealth Architectural Series will launch in the summer of 2011 - pricing is yet to be announced.
