For specifications, see the colleagues.
I had the Samson Resolv 65A long time, and I wanted to change. I had gone on to Génélec 1030APM OCCAZ ', when a friend told me to listen to the last small Yamaha. I had not power up the ass, but the quality ... I use it to sound.
They are in my ass congig hardware / software: MPC2000XL + computer ...

SOUNDS

Incoroyable! Simply ... These are all small speakers, but what we already see is rendered in low which is great ... In fact, I'm not looking for a speaker that will be my sub, but a speaker who will answer the most faithful of a foot and a low, given that I use no infra-low, no worries, it goes down quite low.
For the rest of the spectrum, there is no screaming, everything goes perfectly, it changes me filthy dung I had before.
The dynamic is very good, and the sound has a good potato, even at low volume.

OVERALL OPINION

I have recently, but I have no regrets. Sure, I'd have a second pair, like (to stay true to the brand) MSP10, to the mix, but to make it sound more than enough.
For 300 euros, I think that Yamaha has made super strong ... I hope they will be robust.
