Martin Logan Motion 40i Floor Standing Speakers  

These speakers feature an advanced resolution Folded Motion™ tweeter, a 5-1/2" aluminium cone midrange driver and dual 6-1/2" aluminium cone woofers.

Part of the secret to the Motion 40's outstanding performance lies in the dual oversized black-aluminium 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 our Folded Motion tweeter creates audible acoustic alchemy across the frequency spectrum.
