Not sure if you have interest, but I have 2 pair of proacs for sale right now. both have new surround that were professionally done through Audio Connections in NJ (a top Proac dealer). They are both teak. One is a Studio 1 MK2 and the other is a studio 100. Similar sound for both. No other speaker I've ever heard under 2k will image or soundstage like these two. I also have a set of Super Towers mk1 in teak that I'm selling too. I personally don't use a sub for monitors as it usually takes away from the strengths of the monitor. If you are thinking of subs, why not think of a nice looking tower that does what a monitor does, but goes deeper because of the size of the cabinet. It's also fewer connections and electronics and unless you are an expert in set up, most subs just don't work like they should be. That's my take on hearing so many systems set ups over the years. Bass is very expensive and there are no short cuts not matter what folks will tell you. It costs money to get subs (you need two), cables and crossovers set up properly. I know of a couple of designers of subs who will even tell you the same thing. They design and sell them because they became the rage and it pays the bills, but they don't love them as most don't get two and the proper cables for them.
The biggest thing I take away from speakers is matching them properly with electronics, stands and cables. all make a difference. There are many good monitors out there and some of them are good bargains too. Use your ears and chose who to listen to. All of us have opinions and we all love what we have chosen. Figure out what you want out of a speaker and then figure out what you don't want. Once you get them and have them working, you will probably be vey happy and not worry about what you didn't get. Just my thoughts. Let me know if you have interest in the Proacs. Great luck to you. Have fun with this and don't' over think it all.
