How long have you use it?

its been 4 years that friends are using, if not pregnant already running for 15 years (no blackout note is a day)
btw my friends with whom I turn, uses 4 high-midrange and 2 sub of the same brand (the rytmic 450)

What thing do you like most and least?

the aesthetics of it's enclosure that are quite discrete, the qualiter is a really good set by acute that ford volume becomes a little criad if they are very good speakers.
it weighs not very heavy, size is quite small for what are rectangular and can be stacked between them.

Have you tried many other models before buying it?
not so bad its too numerous to cite

How would you rate the quality / price?
I do not know the new price but I know what worth their price

With experience, you do again this choice?
ben yes btw I vee aquérir rytmic the 450 and 315.
