Just email the spec number to info@eminence.com along with a note that you would like a copy of the params and we will gladly forward that information to you if available. Please include either your email address or fax number. You will find the spec number on a small label attached to either the side of the magnet or the inside one of the basket arms with our spec number and manufacturing/date code on it. The spec number will begin with the size of the speaker (i.e. for a 10" it would be 101123).
