I would suggest calling the Proac dealer you mentioned for product information and pricing. I would also recommend taking the two hour drive to this dealer. Always better if you can hear in person. Make a weekend out of the trip if needed.
A 2 hour trip is nothing. I drove from RI to Annapolis,MD to listen to a pair of speakers I ended up purchasing. I drove 8 hours each way In one day. It was back on December 30, 2011. I was tired from driving over 800 miles, but it was worth it.
