Re: Boston Pros or Mb Quart premium?
Well, I'm going to disagree and go with the MB's. I have ran both in my car. I had a set of Boston 5.25" comps in my kicks and my 5.25" MB coaxils in my rear deck seemed to handle better at higher volumes. They would even drown out the Bostons. I had 100w going to each and the settings were the same. As for SQ, that would be user prefference; compairing soft dome to hard dome tweets. If your willing to give up volume for the sound of a soft dome then go with the Bostons. However, if you like the sound of a hard dome, then go with the MB's and they will also get much louder and maintain awsome SQ.
Since then I have sold the Bostons and replaced them with a set of 6.5" MB comps.
