You can purchase the Martin Logan Dynamo subwoofer at nearly 50% off. This is the best deal you’ll get. It goes down to 27Hz, has an aluminum woofer that at this price point is the best price/performance deal I can think of for under $1,000 hands down. I absolutely loved this sub and it was a great introduction to me for high-end audio. For poor audiophiles, this is a super-buy.
This is rock-bottom used price and to get it for $350 shipped, that’s the best deal around. You can click this link to purchase the Martin Logan Dynamo Subwoofer from Amazon’s web site.
