An immediate improvement

I did not expect to see these so soon!!!

I submitted the subwoofer feedback survey back when Fosi was asking and they released something nearly identical to the specifications I suggested. I felt obligated to buy them because of how good of a match they are! I bought two because they were half the price point I expected with the spec.

For comparison, I used two Dayton audio SUB-1200s. They were $199 each and have front firing 12s with 100w amps. They felt considerably underpowered and I had phasing issues due to their location and lack of adjustability.

Out of the box the Fosi subs are crisp, compact, and very clean cut. I do not like the white. Why it is the first and only color available is surprising. I am considering ways to refinish these soon.

I'm only a couple of hours into break-in and these are much more impactful than what I replaced. The down-firing driver makes a drasticly increased tactile experience.

Musically, they're very clean and easily fill a 16x20 room.

I have yet to listen to them in surround sound, which is a secondary purpose for me.

I estimate with 100 hours or so of break-in and fine tuning phase, crossover points, and port direction, I am going to be a very happy camper.
