Sounds like you should move on to another brand and get a better situation going for the long term.
Have you auditioned Salks?
I won't get this right, but if you have to turn them up to get them fully performing, then there are many things wrong - crossover, cabinet tuning, driver matching, placement, etc. I did have a local buddy with some speakers that only sounded good to him when he cranked them up - they were pitifully tweaked by previous owner into money pits. Once he heard a better designed speaker perform at low levels and loud levels consistently he dumped those bad boys quickly. He also realized a much lower volume setting was all he needed anyways and his wife also appreciated the improvement. Don't get yourself into a bad situation. Keep shopping.
