Up for sale here is an HRS Harmonic Resolution Systems M3X isolation base measuring 21"w x 23"d and rated for 60lbs-100lbs. (blue load) HRS logo is on the 21" side, not the long side. Base will be packed and shipped in it's original overbuilt wooden crate and will come with it's manual. These retail for $3400 currently, so why not save over a grand and obtain this one used. I am downsizing my system so am willing to sell instead of store. Rated 8/10 conservatively for very minor nicks not noticeable from a distance. Buyer pays shipping (probably 75-100$) seller pays paypal fees. Thanks for looking. Please, no low offers. I have two of these should you be looking for a pair for mono blocks, etc.
