280 pound package arrives today

Look at past threads, he's documented past electrical upgrades //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif...

Some of the stuff you wrote in that thread was pretty funny //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

PWND! Whats life without a type r

 
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

 
Type-R will take all of that power with no struggle! //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.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
