I'm in the middle of building a house and I can choose between having 6" 1/2" Proficient speaker installed or I can pay an extra fee for the same size in a Boston Acoustic speaker. I know nothing about the Proficient speakers other than they are owned by Speakercraft and that they have Kevlar drivers. I'm leaning towards the Boston Acoustics but it is an $80 up charge per speaker sets. Any advice?
