As many of you probably know, all 40bea05699cf5192813d9535f3e527cas can be equipped with new and better tapes in the bass as well as in the midrange, treble range. The exceptions here are the "Stage" and the "Studio Ribbon Array", which use double-sided bass diaphragms. With these, one-sided ones can be retrofitted, which are adapted with the help of small modifications of the crossovers. http://www.apogeeribbons.com
