The price, the different reviews here and there, the Presonus quality and their nice look!

For my home studio, pre-production, mix, etc.

I use them with a Focusrite saffire USB and Reaper.

SOUNDS

I won't talk much about "frequencies," but everything seems well balanced.
The mids and the highs are pretty forward, which is quite normal given the speaker format.
That said, the lows are very present and I have rediscovered some of my mixes with more precision!
The controls on the rear panel allow you to correct the sound according to your home studio setup (speaker placement, etc...).
I haven't spend too much time with that, but I'll update my review asap.

Listening to different albums you can tell right away that they are very good quality speakers!!!
And you have a good reserve in terms of power!!

OVERALL OPINION

I have a limited perspective right now (I've had them for a week), but I think they are a great value for money!
