First of all, why are your existing speakers 14" from the wall? Is that where they perform optimally or is this position for aesthetic reasons such as room furnishings, WAF, etc.? If you cannot place the speakers where they sound best, it will do no good to purchase better ones in the ProAc line. Instead you should be considering speakers which work well in a room your size and near the wall. I would suggest that before you spend any money, experiment with speaker placement first, it can make a huge difference in the areas you are looking to improve upon and costs nothing at all unless there are matrimonial restrictions involved.
