Product Information

The elegant Motion 40 tower speakers are the newest additions to MartinLogan's award-winning Motion® Series. Voice-matched with the entire Motion Series products, the new Motion 40 speakers feature MartinLogan's advanced resolution Folded Motion™ tweeter and have been designed with a luscious high-gloss piano black finish, subtle angled-top cabinet with soft radius corners and signature MartinLogan perforated grille.

The elegant Motion 40 features an advanced resolution Folded Motion™ tweeter, a 5-1/2" aluminum cone midrange driver and dual 6-1/2" aluminum cone woofers.

Part of the secret to the Motion 40's outstanding performance lies in the dual oversized black-aluminum cone woofers paired with a rear-firing bass port. The oversized woofer design creates increased cone area delivering higher output and audibly richer, deeper bass performance than it's slightly smaller sibling, the Motion 20. The addition of a dedicated mid-woofer also promotes an even more open, revealing and authentic sound in the critical midrange. Pairing this powerful trio with MartinLogan's Folded Motion tweeter creates audible acoustic alchemy across the frequency spectrum.
