Me vs. spiders thread ? //content.invisioncic.com/y282845/emoticons/chicken.gif.218ea7401db50d5e31a7e0b37e05e21e.gif//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
Some of the stuff you wrote in that thread was pretty funny //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

Last night I re-assembled one of the beasts. Used the hammer to fix the
faceplate and replaced the handle screws, bent. Looks better now, time
to do the second amplifier then I will have peace regarding these two monsters.
There is no way to upgrade the capacitors, the internals are crammed already
and the capacitors they chose are already the best that can be had based on
voltage, capacity and physical dimensions. But it's always evil to scheme up
a plan B... Like... Imagine having another 4RU chassis with nothing but capacitors? Zapco did this 20+ years ago with their model 200 amplifier. They
sold a stupid module for $75 called 'ESM', energy storage module. A box with
two 4700uF capacitors that is in parallel with their external power supply.
.. so how about a monster ESM for each Crest? I don't have the room to do this,
but the idea is pretty sick.
General idea. Since it's a class H power supply with four rails, I would be only
concerned with the high rails, which are +/-160V.. so the ESM would only supply
extra capacity to those rails because that is where we want it most, for high
power use. Who cares about high capacitance at low power.
If we were to stick with a 4RU chassis we are limited to 7" tall.
CDE has 5 7/8" tall x 3 1/2" wide, 61,000uF 160V {200 surge} capacitors.
Lets say 6 x 2 matrix for each amplifier. ESM would have 6 x 4 matrix
with 24 caps to serve two amplifiers.
ESM would be rated for 366,000uF per rail for two amps. Or 732,000uF
per rail for one amp if you wanted one ESM per amplifer. /hehehe
Energy storage for two amps would be based on 160V, 366kuF.
4684 Joules per rail for two amplifiers or 9369 Joules for one amplifier per rail.
For reference, a car audio amplifier with 1 Farad capacitor {1,000,000uF}
has 103 Joules.
For another reference, the new Rockford Fosgate 15KW amp {Hybrid}
has somewhere around 225,000 Joules. They use the new hybrid caps
used in electrical cars. But anyways, that RF amp is misleading, it's 15kw
rating is not using the RMS method, it's a peak rating. That was a hot debate
in cyber last month... It took me 5 minutes to scheme a design based on their idea,
the class H power supply with brains. Who knows how they implement the idea,
but it's getting a patent and we can alway look at the patent. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

oh come on that thing wont even move the cone with that teeny tiny amp //content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif its a type r remeber ? the wmd you can buy and use as a sonic weapon vs anyone you dont like //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif
