Martin Logan Descent i Black Ash

Up for sale is my Martin Logan Descent i in Black Ash.The cabinet and grilles are in good to very good cosmetic condition overall but do have some blemishes here and there.The drivers and amp plate look great and function perfectly.
I would rate it a 7-8 depending on how picky you are with your gear.
It's balanced force triple 10" design produces tight, powerful bass that extends down to 10hz in my 3000 cu ft room.It is also one of the most musical subs I have come across with very effortless,punchy bass which makes it extremely versatile for music and home theater use.
I have the rubber spikes installed and the power cord is included.
I don't have the original box.
Local pickup is fine and I can drive a reasonable distance to meet as well.I can ship this through my local UPS store but it will be your responsibility.
Email with any questions.Thanks!

DESCENT i
Ultimate Bass

Building on the groundbreaking technology of the original Descent, the Descent i incorporates new features and enhancements that simplify system integration while improving performance. Its signature three-driver, force-canceling configuration virtually eliminates bass-blurring cabinet resonance. And each rugged, custom-built aluminum-cone driver is servo-locked to its own sophisticated, high-power amplifier. The result is dynamic, unrestrained output to the very lowest frequencies, yet with clarity and definition approaching that of electrostatic transducers.
