Here I think after a month of use.
I use this box in addition to 2 RCF 315A speakers in sound of a pop / rock group "traditional" (singers, guitars, keyboards, bass, drums electric), and I'm really happy, as an adept good sound than the big sound.
Compared to pregnant FCR, it is a bit light in power, since it is pushed to 3 / 4 where you push the speakers at the half for a balanced sound.
However, it is enough to sound with a wide hall of 100 people with a correct volume. (Note: not for the techno & Co. based on "dum dum dum" in the sub-bass)
And at the sound, there is clearly impacted "by the box" and "after the box."
When you put the music, it almost seems to hear a sound rather than stereo sound (if you know what I mean ...) In short, the sound is very round, with low well-filled without being invasive, nice what!
He was pushed a little to see ... as a result, the integrated limiter came into action (shown with a small LED that flashes from time to time), but did not sound distorted or heard a bad resonance. (It's hard for me to make an assessment provided more as it is the first subwoofer I face)
In short, this box really brings roundness we lacked in the bass, it lacks a little power in this configuration, but since the models easily weigh over 15 pounds heavier (the beast is already 24 kgs), c ' is really a good compromise for a sound that moves in our cars, not in a van!
So no regrets, on the contrary.
