sundownz Posted December 22, 2011 Report Share Posted December 22, 2011 Newest production run arrived a few weeks ago -- we changed the output FETs to the same parts the newest 3500Ds are using (more powerful) and made a few other small tweaks. 0.5 ohm performance is now just as good as the v.1 1500D while maintaining the slightly better 1 ohm performance that we had already achieved on the v.2 model. I don't have any 1500D v.1s around the shop right now so I'm using previously tested data : 1500D v.1 POWER : 1970 Watts AMP VOLTAGE (measured) : 49.25 V AMP CURRENT (calculated) : 40 A ACTUAL IMPEDANCE (calculated) : 1.23 ohms SUPPLY VOLTAGE : 12.85 V 1500D v.2 POWER : 2030 Watts AMP VOLTAGE (measured) : 47.4v V AMP CURRENT (calculated) : 42.8 A ACTUAL IMPEDANCE (calculated) : 1.11 ohms SUPPLY VOLTAGE : 13.3 V So essentially identical performance within margin of error now on 0.5 ohm operation -- which is great since the v.2 is 1.6" shorter than the v.1 model was ! I'll have to get some 16v testing done too -- but I may wait until I actually have a v.1 model 1500D around to do it head to head. I'm sure I'll get one traded in again eventually.

hartman209 Posted December 22, 2011 Report Share Posted December 22, 2011 so are prior rus of v2s compareable at 1 ohm to the new run of v2s at 1 ohm Quote Link to comment Share on other sites More sharing options...
