I'll get that and run the tests again. Thanks.\n\n\n\nBut 2 drivers in one box means 1\/4 of the power, right?\n\nI'm going to ask you to help me figure out what to do with them, even if it's only for car audio, after I figure out a few things and get highfigh's clay recommendation to test against what I've done so far.\n\nRob (anunaki) pointed out that they might be one-note wonders.\n\nI gotta go mess with routers and I gotta say, that's my least favorite tool. Anything spinning at 30,000 RPM is just wrong.\n\n\nSealed box, if they're suitable for that, means the response will cover a broader range than a one not wonder which is always ported, the port frequency is very close to the Fb and does almost nothing outside of that peak. Great for some music, useless for everything else.\n\nTwo drivers in series will produce the same SLP as one because the voltage has been halved, but the cones move more air, in parallel, the impedance is halved AND the cones produce more air, so it's like quadrupling the power with a single driver. However, you need to make the amplifier happy and the Vb will be larger, whether sealed or ported. \n\nHow do you make a router spin at 30K RPM when it has all of those cables connected to it? \n\nOh, right.......\n\nTake the cutter to the material and it's safer than taking the material to the cutter- I made a mistake once and narfed my left index finger. Not bad, but it was a wakeup call. Next time I used it, I walked up, paused and said "So, we meet again".
