hi there.. I have a wharfedale diamond speaker set. 8.3 , 8.1 and center.. a week ago.. I got to talk to a custom speaker maker .. I asked about the speakers referring to the diamonds low sensitivity being 86... i asked if theres something that can be done about this..like a tweak or something.. he said that theres a jumper/capacitor (im not too sure ok) that can be removed and replaced by a wire on the crossover.... by doing so would increase the sensitity a bit..around 90+ probably... is this tweak a good sugggestion??? just curious.any advice??
