Musical subwoofer under $2000

To better understand what you mean by a "musical" low frequency producer.

Imagine you had two units at your home for audition individually during the same session. They are both properly positioned in your spacious room and adjusted to a point were you can not discern were the speakers end and the unit takes over the low frequency output.

Played individually turning each one off, its apparent one displays a noticeably greater sense of extra low frequency fullness (not loudness) of your main speakers presentation than the other. Which units presentation would you consider to be more musical?

"@kennyc  Usually "musical" means enjoying the music as a whole but can also be at the expense of detail and accuracy. What you are looking for is an "articulate" subwoofer where the bottom notes sound like real instruments and not a boomy mess."

Kennyc,  Absolutly. My description completely overlooked the mentioning of articulation in lower frequency presentation in my question to the OP's meaning of 'musical'. Thank you for making that point. 

I was attempting to bring to the OP's attention that his choice is a -6dB bass speaker that simply doesn't go that low with any authority and whether that was a priority. 

@mofojo   Nice to hear a realistic direct experience.

I had an early version F113 in the house. When used with the early Velodyne DD Optimization the smaller F113 was surprisingly every bit as potent as the larger DD-18.

At the time both manufacturers were not only similarly priced but seemed to be on the same developmental timing trajectory. I too had a similar positive service experience just prior to the 2019 sale.
