[QUOTE="Peter Morris, post: 213153, member: 652"] The 12N610 should perform almost the same as the RCF 12N351 except as Max points out it will be limited by Xmax (3.5mm Vs 6mm for the RCF) @Max - I get a slightly different curve to you ... but if I make the input voltage about 102 volts and look at the cone excursion I don’t see the problem at 200Hz you are showing ... BUT ... if I try the "Tools - Max SPL" it shows up like yours - Hmmm something strange going on. Its also worth mentioning that with a 100Hz 24dB LR crossover the input power will typically be much less (-6dB) around 100Hz; where the Xmax limit occurs. Although if you still put maximum power in you will exceed Xmax (linear) but not Xmax (mechanical) with the RCF or B&C. [I]FWIW your plots looks like the box is tunned a little high - the sim will not give you the correct result because the ports are next to the walls, this makes the port perform as if it were longer.[/I] [/QUOTE]
