if i have to go to all the trouble to take picsof the ul-12s i guess i could take a few pics of my class a amps, my prototype 5 channel c-mass amp as well.or how bout my prototype 2 1/2 critical mass mids or my new ul6,s naw yall wouldnt believe me any way lol.

This is getting really funny:laugh:, how much trouble is it to take a picture? and your other stuff has nothing to do with this, and I will add that your class a amp is not truly class a, although it is a nice a$$ amp.

And I would believe it if I saw a picture:laugh:

Stop being a whiny bitch, jesus christ. You're selling a VERY expensive item(s). You have no posts, no references, and no pictures...get off your high horse and see the situation through someone else's eyes.

ryan lol is what adults use in internet replys refering to a joke or pun. since kman seem to be enthowsed about c-mass i thought he might enjoy seeing some one off or rare c-mass equipment. guess not . and as far as vouching didnt 2critical VOUCH for me

As quoted by the almighty Squeak

"I can state with unarguable certainty that both the ULA-A4x350 and the ULA-A2x700 are NOT a pure class A amplifiers if the specs on the website are accurate. Class A amplifiers have a maximum efficiency of 25% (mind you that's maximum, so most will fall even below this level of efficiency). So what type of current draw would a 1400w RMS amplifier have on an electrical system ? Well, if we very favorably assume that the efficiency is indeed 25% and it's operating on a steady 14.4V electrical system, it would draw a continuous 388A. Not during peaks. Not only a full volume with sine waves. CONSTANTLY.

So, it's pretty easy to reasonably demonstrate that the amplifier does indeed at some point operate in something other than Class A. Now, it's entirely possible that the amplifiers have what is called a "high bias". Which essentially means they operate in class A mode up to higher levels of power than what most other class A/B amplifiers do. Some examples of this would be the old Monolithic amplifiers. A more recent example would be the Tru A Class, which operated in class A up to 25w per channel (then switched to class B).

A simple tell here, and for any class A/B amplifier, is the amount of idle current draw. Since we know that class A amps will continuously draw full power from the electrical system, even at idle, the amount of idle current draw will represent the maximum amount of power the amplifier can supply before falling out of class A operation. For example, if the idle current draw was 2A, with our knowledge of 25% maximum efficiency and an assumption (if we don't know the actual voltage) of an input voltage of 14.4V, we know that best-case-scenario for class A output is 7.2w total (for a 2-channel amp, that would be 3.6w per channel).

So, what is the idle current draw of those Critical Mass amps ? Because I highly doubt it's 388A "

I am not a cmass expert, but I have been schooled by Squeak. also i stated that 2critical did vouch for you smart a$$//content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

Heres the money now wheres a pic of the woofers //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Now thats how you freakin do business...

do you have a reply sir, because I can call the almighty OZ in to join us if you would like.

i didnt ask you what someone else thinks . so you dont have anything to add? but i will say this statement is not fact. the c-mass amps are class a from start to finish.
