[QUOTE="Peter Morris, post: 204140, member: 652"] The critical parameters for a driver in a horn are the moving mass and the strength of the motor. The 12NDL88 Mms is a bit high compared to the RCF MB12N351, which is more efficient and provides a smoother response in this horn; but it does not have as much Xmax. The 12NDL76 (when you model it) has a slightly smoother response compared to the 12NDL88, is cheaper (much cheaper than the RCF ) and lighter ... and I had 4 :-) ... part of the reason was to test a cheaper option - 12NDL76 with a standard BMS4594 There are a bunch of other drivers including the 88 that I would love to try in the DIY but my $$$ were limited. FWIW – B&C 12/14/15NDL88 range looks fantastic for a lot of applications - a great compromise between efficiency, Xmax, SPL, weight, cost etc. FWIW Here is a new design ... it use 2 x B&C 14NDL88s [/QUOTE]
