I use it for 2 weeks now.
This box lightweight (21.7 lbs) is convenient for transportation, especially for a single person, he uses a 15 inch (38cm) and the neodymium amplifier 600 watts class D No noise suspect ignition or extinction. No operating noise (Made in Italy). Low quality is the appointment and you can choose the crossover frequency is 12Hz or 80hz. Personally I chose 120hz because satellites are Art300A RCF and the result is great. This box also has 2 outputs unfiltered very useful for two other speakers (eg returns). The input sensitivity is 22kohm a little higher than the satellites so just find the right balance of power or decrease the volume of the box or to increase the volume of satellites. Warning this box has the "potato" it grows strong.
Short one regret is that did not have the money to buy a second because it is a bit expensive but really worth it.
