hello dear Sound guys, What about this Beauty +30years old tank? 
I have some 8x Crest 8001 in my inventory, and I was thinking out put some to sale, but after I see a Friend using one at full tilt One week long on sub duty 2ohms 2x dual 18 per Chanel , with no trouble at all! All week long full tilt , 2ohms sub , clip light always on! The amp had good headroom too on bass notes in full tilt clipping! 

I could not believe! This is a Legend of a an Amp!What do You guys think?

This Amp is almost impossible to kill! 
Which of an modern amp could do this too and survive too?

It's a great amp for running 2ohm full tilt all night long that's for sure. 

I think what makes them stand out is they were designed to excel with a 2ohm load, rather than just cope with one. Drivers were lower powered back then so running 4 on one channel of an amp was more common.

Nowadays best professional practices would call for 1500w (or even more) per driver more often than 750w, but when the 8001 was launched, 750w per driver was about right.

8001 @ 2.6 ohms that’s the magic formula. You will get over 2kw.

Thats what happens when weight is not a factor.

I cant imagine how a Crest 9001 would performe in similar scenario! 
Would performe equal but with a very stronger punch??

These Crest 001 are super overbuilt!

EDIT:8001 just does not have enough O/P devices, PSU, to drive 8x of today's modern drivers, rated 750W-1200W.

Last Saturday,  we ran 8x PD1850s, off 1X Powersoft K20, all day, "outside".

Off domestic 32A ring main.

Bass was heard approx 1x mile away.

Now have bookings for 3-4x more outside events.
For those playing out regularly, there is a time to move on, from Heavyweights.

There are smaller companies that design amplifiers that have no issues driving current drivers (no older than 5 years old). However, if you have a weak back, or short on voltage, they are not aimed for the average sound man.

Increasing number of UK based Reggae Soundmen, are putting away their proprietary, custom made heavyweight amps, and buying Powersoft K20 or X4/X8 for sub.

I've heard all of these, and can see no reason not to use them over transformer amps, unless your sound system can't pay for them, with gigs.

The Powersoft K20 is used globally by many. However, for those that think outside the box, don't mind the weight and have ample voltage at their disposal will look at other options other than the K20. The price of Powersoft K Series is steered primarily on its on board DSP. 

It is a matter of moving with the crowd or moving in your own direction. So having alternative options are always good. 

2 ohms per channel left with the 1990s as far as I am concerned. Amplifiers are too light and take very little rack space these days to focus on one amplifier driving 8 loudspeakers.
