Subwoofer powered subwoofer with a 400w 15 "
I have this box for the past one year and I am satisfied!
What is surprising at first abort is its weight, a pen vrible: 23kg! plus the handling is good thanks trs good grip, it adds this! And I say, shit, it's too lightweight to ring this thing: either the hp is crap plastic or wood that is worth anything ... brief is not won!
Ben I have aa plant sonn the first time. It's really not bad at all especially considering its price: around 500 euro. I had tried 2 or 3 until around 600-700 euros, and I prfre the l!
2 little things I do not like: 400 w 600w but it's even better then the above MODEL If you are not limits in place will, for the collection's outdoor, better.
And 2nd thing is, it is quite fragile at the paint / wood, you hit it and there is an impact on! shame they are not being protected, put plastic corners, but these can be added!

I agree with Previous wash. Bought some time ago and some APRS uses two satellites agreement Rope B, cest trs well for small service room average. The 15-inch HP is a good bill. Perfect sound and the door is hitting good trs. The manufacture of the body is light weight Designed and dun, but we will have to invest, the manufacturer forgot to put the corners mtalliques less fragile than the plastic corners a penny-pinching economy The housing dlivre a sound pressure of 127dB SPL. No vibrations even full power, still confirm the reliability of the amp which is cooled by a small fan.
For large rooms jOperation 2 subwoofers and 4 satellites variation on rock style of music, entertainment, coupled with two equalizers and active filtering for balance satellites and caissons. We obtain a system that a remarkable quality and a thundering performance.
Conclusion: the strength power and a high yield, weight MODR each box with its own amplification. I do not regret this purchase trs good report quality price. It remains to see the reliability of Systm but I do not know ...

Hello,

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.
