I've heard those baby Pro-Ac's once, and IMO that is one sweet little speaker. Truly impressive sound! Only downside I see with them, is a person cannot expect a small mini-monitor like this to give window shattering low register bass. That can be corrected though with a good Sub that is properly intgrated with the ISc.
JT brought up some great ideas for a good kit from Madisound, I've dealt with Madisound in the past for other needs, and these folks are great. I've honestly not heard any of their kit speakers though, but they do seem to have promise as great speakers which can save some coin.
The other option one could perhaps consider, is a true studio monitor? What about a pair of JBL 4312's, or the like ? Mark
