For my summer rebuild I'm considering doing either 2x the new Sundown X-12's or some Fi BL's but I'd like some opinions on the BL beforehand. The main thing I'm concerned about is that they'll be too peaky, I ran a pair of them through WinISD in 4 cubes tuned to 32hz and it showed them EXTREMELY peaky and that is not what I want.

So anyone that has heard or used these please give some input.

The are a number of helpful threads in the Fi section here.

Fi does not model well at all. Go with what Fi technical recommends for enclosure size.
