Genelec Speakers opinions

If clarity, accuracy, dynamics and ability to play loud with correct timbre is your thing... then either is a great choice. Bass will be lean and tight...the 1037C can be soffit mounted for even better performance. (Personally I would go for the three ways as long as your neighbours are not too close)

Active speakers have significant advantages over passives and really have no comparison in terms of dynamics and clarity...not a sound for everyone though. If the source recording is poor then you will hear it...warts and all. You will hear EQ and mix adjustments made during a track all too easily and some people do not like this.

I thought the Genelec's sounded great! I would have picked them over the Dynaudio's that were in the same room any day.
Shadorne ..pretty much said it all.

Heard them at the Montreal show. Best surround system I've ever experienced. I want them! Someday.........

Brutally revealing asn Shadrne alluded to. These came from the pro world as top shelf studio monitors. They are not going to flatter the music or mix in any way--you get the truth. For great recordings and great gear upstream--I would love them. Also, if you want full out dynamics (particularly if you doing HT) these speakers are pretty incredible. However, if you are looking for a lush flattering sound--these are the wrong speakers. They are anything but that. So like many things, personal preference and taste play a large part in whether or not they are the right speakers. The are excellently engineered and perform at extremely high standards--but only you can decide if this is what's right for you.
