[QUOTE="Peter Morris, post: 133200, member: 652"] Re: New DIY Mid High [FONT=Calibri][SIZE=3][COLOR=#000000]That’s the opposite of reports I have heard; people have describe the sound as having a lot of impact, like being hit in the chest with a hammer, however they have all been in relatively small boxes - around 190L per driver. [/COLOR][/SIZE][/FONT] [FONT=Calibri][SIZE=3][COLOR=#000000]I think a lot of people are focused on LF extension and end up building designs that are under damped with a LF resonance peak. They sound exactly as you described. [/COLOR][/SIZE][/FONT] [FONT=Calibri][SIZE=3][COLOR=#000000]I have always like the sound of slightly over damped designs using drivers with a Qt of about 0.3 like the 21SW152. [/COLOR][/SIZE][/FONT] [SIZE=3][COLOR=#000000][FONT=Calibri]I believe Fulcrum use this driver (or similar) in theirUS221 and EAW in their SB2001, possibly Danley in their TH221 (?)[/FONT][/COLOR][/SIZE] [FONT=Times New Roman][SIZE=3][COLOR=#000000]I guess I'm about to find out :)~:-)~:smile: [/COLOR][/SIZE][/FONT] [/QUOTE]
