I think it's not a 'serious' speaker. I think it's a party speaker that can also do the audiophile thing as a bonus.
Correct, it's a throwback to the old big-box speakers, but using good quality parts, and a much stiffer box.
It will never "disappear" as easily as any of our other designs due to the large, wide baffles, but you can crank it up, and get rather deep bass.
Imaging is quite good, as is soundstage width, but depth is limited to the space between the speaker's.
It's not a speaker design that's for everyone, but there are people who are looking for that sort of design.
