I needed multipurpose loudspeakers capable of operating alone or with subwoofers.
I chose the GC7 153 but I asked what the ATP is replaced by a 80 + tweeter powerful and that is where Samuel told me the DE10.
Absolutely reliable as a tweeter, I think he can get closer to its HI-FI.
The sound is very sharp, and perfectly DE10 reacts to changes desired by means of an equalizer for example.
Excellent sound so.
I use it for 3 or 4 years.
For value for money: BETTER NOT!
