Lets see how well you've been paying attention to my crazy posts....

Post your guess on what two used amplifiers I just scored on the auction site today.
{BTW, I'm done collecting amps for my audio project ..... honest injian :banghead: }

:crazy: :crazy: :crazy:

:wave: Bonus round question:

:hide: Add up the total rated wattage of the amps I collected and what total wattage would
that be ?

:crazy: :crazy: :crazy:

A matched pair of Crest 10001s

Bonus Round: I don't know if the collection includes units beyond those two and at what impedence you're going to run them. *shrug*

You are --> http://images.hollywood.com/images/large/l_2443507.jpg

Bonus round clue: 2 Crest 10k + ten more amps. Use lowest impedance rating
of the amp to figure out total. /yikes.

:cool:

Your running them at 2 ohms bridged for a total of 30,000 watts outa the two of them?

The AC power line I installed a while back was over-engineered. I used
three 2 awg cables {120v, 120v, neutral, and 4 awg for safety ground
for a 240VAC subpanel in the sound room. To keep losses lower, all amps
will be re-wired for 240VAC operation, cuts current draw on that main line in half.

Here is the battle station plans, revised.

PLX3402 bridged -> four tweeters, parallel 3.2 ohms. {left channel}
PLX3402 bridged -> four tweeters, parallel, 3.2 ohms. {left channel}

PLX3402 bridged -> four mids, parallel 2 ohms. {left channel}
PLX3402 bridged -> four mids, parallel, 2 ohms. {left channel}

Crest 10k bridged -> four 15" woofers {not sub duty}, 2 ohms {left channel}

... repeat above for right channel.

Two PLX3402 may do center channel and surround duty, unsure.



Ten PLX3402 -> 34,000 watts rated
Two Crest 10k -> 20,000 watts rated {second rating 30kw}.

We know that these ratings are based off some other industry standard
spec, not really the sine wave/rms method. So.. these are really 'musical' power
specs, they can deliver these power ratings on lower duty cycles {music}.

But the Crest is old school, I snagged the schematics and checked it out.
It's has big azz balls ... four transformers, 14 power transistors per rail,
which means 14 push, 14 pull transistors per channel {56 transistors total}.

PLX3402 has 16 transistors total by comparison and the power supply seems limited to 2kw
using rms method. /rough guess .. their power supply seems to be the weak link, hence
it's job is for tweets/mids. Perfect for that job.

So.. to drive the woofers with balls, the Crest makes more sense. The clipping
headroom is 320V {not factoring in losses}, PLX headroom is 260V.

I have to bring chaos to order ...

Ozzfest in a couple of years, free entrance tickets, but you pay traveling fees
to check it out.

To make the comedy higher, the room is small, one chair.. so this will be a torture
chamber, like jumping out of a plane with no chute ................................

I need subs though, no room for them ....... so we have to live with 32hz - 35hz
ported woofers, not really for HT but for metal music -> yay! ........... // slayer! //

Ya know what, I'm tempted to make a wikipedia entry under Overkill. Its gonna have thylantyr and what you just put about your insane toture chamber.

Cause, that is NUTS.

It is now one of my goals in life, to listen to your toture chamber and subject myself to the punishment thyantyr.

It's like going hunting with a nuclear bomb!!! You know when you have to run seperate power you have a problem!!

It will be good punishment, you'll see. It's totally opposite of what people think
when they see big speakers with lots of amps. The trick is to get those unique
speakers. I found some very unique drivers for this project. I have a tweeter
that can do what ten PT2 do in an array but offer better SQ and low frequency
response. Put 16 of these tweeters in a room ;)

The midranges I'm going to use are a special order from France. I ordered them
2 months ago, arrives in a few weeks. These mids and tweeters have a very
special synergy. I've bench tested one tweeter and one mid together and I was
able to 'amaze the natives'.. Imagine what 16 tweets, 16 mids will do in the final
design ;)

The woofers are special, wideband woofers hand made. With clever use of an
EQ and doing a blind test, I can make you think they are tweeters with 16mm
of throw.

It's an amazing recipe that I spent years locating and testing. I need 8 more
tweeters to finish the driver collection phase of the project. It's going to be
crazy for sure.

Which efficiency are you referring too ? driver? amplifier ? money ? time ? :cool:

Headphones to me are amazing considering how it fits in the less category.
But they can't touch the battle station on a different level.

A fighter can kill someone with his bare hands, but I like to weild a war
hammer.

A thief can kill by shooting an arrow, but I'd prefer to get up close and backstab.

A Mage can kill with a dagger, but I'd prefer to cast a fireball.

It IS fun to impress with less....

Thats kinda the reason the people on my dorm floor are floored with the output of my little 4" drivers and think I'm bull shiting them when I say they get a max of about ~20 watts.

The less part can also be cost related, not quantity. So... 49 cent NSB are impressive
especially when I got 3400w/ch on them and they are rated for 5w rms each. :cool:

Impressive with less on a different level. :yumyum:

in the past 23 years of doing audio ? // rofl //
