[QUOTE="sundownz, post: 6465071, member: 549523"] [IMG]http://www.sundownaudio.com/misc/protos/Monster_12v/CIMG3080.JPG[/IMG] 155.1 dB - woohoo [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] This was with a "Monster" prototype woofer -- not a production speaker. Interestingly... with all my tweaks to the Z v.2 prototype it was doing the same numbers per watt up to 2500 watts (I stopped measuring with the Monster at that point). So... I may be able to match this with a full production trim Z v.2 driver. Previous best was 154.9 with an 18v electrical system and two SAZ-3000Ds on the sub... this time I am on 12v but with two SAZ-4500Ds (power is similar). Some more pics of the setup : [IMG]http://www.sundownaudio.com/misc/protos/Monster_12v/CIMG3082.JPG[/IMG] [IMG]http://www.sundownaudio.com/misc/protos/Monster_12v/CIMG3083.JPG[/IMG] [IMG]http://www.sundownaudio.com/misc/protos/Monster_12v/CIMG3084.JPG[/IMG] I haven't played with front to back box positioning since I built the new amp rack (yah, slacking... I know) -- but I'll work on that a bit when I get time and see if I can increase this. [/QUOTE]
