I can’t speak to the MOFI speakers but I’ve got a pair of Fyne 701sp blessing my ears and couldn’t be happier. There’s just something about an 8” woofer, great in many areas but actually where I’ve noticed the most meaningful benefit over the F1-5 I was considering is with the vocals, scary real in tone and size. I auditioned the Focal Kanta no1, Fyne F1-5, F1-8 and 701sp and while all three disappear amazingly, control the sound with ease and are fast and tight, the bigger woofers just take vocals to another level. I’m using a JL Audio Fathom 112 v2 sub so I’m not worried about the low frequencies, I was trying to dial in the mids and highs.
Anyways, I’ve absolutely become a Fyne fanboy. Love everything about the F1 and SP series.
