Why so many JL Audio Fathom subs for sale I wonder

Great thread....I have thrown the question out here on Audiogon in the past about the worth of adding a sub to a 2 channel system. Everyone here was great with informed responses, however, I agree with James 63's answer. A two channel system sounds best as two channel system. I auditioned only the REL's that were to be used with Sonus Faber Cremona M's in a room that is 13 1/2 feet across, 21 feet deep and with a 7 foot ceiling and is all ASC treated.....I know that you have to find the '' right '' sweet spot for the sub to work correctly , but .....I think that I would rather save the money spent on a sub(s) - and upgrade the speakers in a strictly 2 channel system. Just my opinion and I'm sure some will disagree, and that could a reason why you do see them up for sale.

When I heard a single JL in an extreme high end 2 channel system I was very impressed. Sounded like the real thing, very, very good sub. I would not worry that they show up used!

I only see a single F212 up for sale as of now.

Subs sound incredible if placed center between the 2 mains. Not only because it is more smooth, but because phase can be dialed spot on.

Move your equipment to the coner, put the sub under the TV. Then you will love your sub.

To its ability to output well defined extra low frequency the JL can do an outstanding job. I've heard their technical support can be very helpful. The JL Audio Automatic Room Optimization is very useable but may need updating. The JLs brut force paired with an Audyssey system or similar, would make it a contemporary world class performer.

Understandably, the failure to successfully integrate a subwoofer by selecting a favorite recording with deep bass content and simply adjusting the crossover, volume, and location is stunningly outmoded.

I've been in many post production studios and all of them use a sub/s. With decent low frequency room equalization almost any subwoofer can be a useful addition to almost any system IMO.
