I have them for two years. I have purchased in single S115 Version ((not C115 are more beautiful but also chres - the tweeter is the same (2 ") there is an error in the docs) purchased in super promo at the corner store. I jump on it. Despite everything they cotent to nothing and are of excellent quality! They are moquetes so it never will traces of stripes. In listening, I clearly boosts the treble with ProcC 10 dBA at 20 kHz and a bit medium 700 Hz and decreases a little lower medium Hz -3.5 dB for them sound a little more professional and less-mobile disco sound. bloated block they accept these corrections without flinching and seem to love it even has ... Everything with Diverack dbx. I associate the (4) with two subs Meyersound 650-R2 and adcolle !!! Awesome! I dviss the facade grid in order to insert the trans-sound black foam Meyersound (among Dispatch) similar to the tweeter, and they are more beautiful ... (I did not want to mtallique grid C115 front tweeters)
The result is stupfiant! It is almost with L-Acoustics ... (I exagre)
A case for the quality provided. Congratulations (again) Yamaha!
