[QUOTE="TaylorFade, post: 7778098, member: 618111"] I'll chime in here. DD rating their amps at lower voltage is good for two reasons. First, it helps with competiton ratings [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] And more importantly, it gives you a much better idea what you'll actually see on a 12v system. It is true that DD's (well, at least the M3a) don't like much over 15v, they certainly make more power at higher voltage. they don't open up like some *coughD5cough*, but obviously they benefit as evidenced by my testeing last weekend. DD M3a - 3,657w @ 11.2v - 4,088w @ 13v 400+ watts isn't earth shattering, but that is only a 1.8v difference. If you can hold 14v, you're looking at a 1k difference. And in the world of SPL, that 400w was worth .8 on the TermLab. [/QUOTE]
