FATHOM 12 INCH F112V2 SUB-WOOFER. Purchased in April 2020 from The Gramophone in Edmonton Alta. A remarkable unit, and arguably one of the best sub-woofers on the market. It is tuneable to the room via its included microphone - and has a host of other features to further tune it to your satisfaction. It has both RCA and balanced connections, and auto turn-off. (Balanced connections are recommended - a pair of such cables are for sale separately on request) The sheer power of this unit is something to behold - of all the subs I have owned (B&W, REL, etc.) it is just in a class of its own. Absolutely the best there is for Home Theatre setups. The unit is in like new condition. (Except, alas, there is a slight amount of cosmetic damage to the black finish on the right corner - see the picture.) The warranty has expired. The new price of this unit is in the high 5K range, at least. It is very heavy, hence expensive to ship. Personal pickup is requested, and would be a very good idea to prevent damage.
