Yes the amp is designed to work on 120V though I didn't see an image of the power receptacle or cord to see if its IEC compliant with a true 20A outlet. You may need a converter cable to use it on a 20A line but I would also verify with the manufacturer. I talk about this in my Emotiva...

how about you just rate it like the manufacturer did. The long term power is 2.25 kwatt and dynamic power is 4kwatt.

Tom look at the fine print. Those are burst tests done on a 50A line. Who has a 120V/50A line in their house? The manufacturer actually rates long term power at around 2.2 kwatt. but again, those are under quite ideal conditions. Your website mistakenly lists 4kwatt as RMS and 8kwatts...

It doesn't matter. The power ratings are unachievable using 120V lines. Not blaming you for using the amp as I am sure its a good product, but the overrating crap just gets out of hand in this industry. Call it 4kwatt burst and we won't have as much of an argument.

Regardless, the power rating on the amplifier is ridiculous. I've seen that exact amp used in other subs that rate it at 1/2 that power which is more realistic.

Interesting rating on the power amp though not achievable unless you're running 220V/20A service even with Class D efficiency of 95%. The website says this only runs on 120V so you would need 35A of current to achieve that kind of power level continuously. What is the rating on the slo-blo...

yea but a lot less maintenance :)

thanks Steve. In fact, this is a calling to All Audioholics forum members. You can help us out by posting new product threads in our forums. Step1: Chose the product you want to discuss Step 2: Select the appropriate forum area to post about it. IE. Receivers, Speakers, Subwoofers Step 3...

All; We are in the process of completely redesigning Audioholics including changing our CMS to Wordpress. This is a huge investment in time and $$$ for us but its much needed. This will be the official thread for feedback from you. We need your help and suggestions. My goal is to have the...

Multi-tone Distortion Testing - continued Guys; I'm building a 32 tone multi-tone test suite in the APx585. This will most closely simulate music program material. I need to run some tests to make sure its a good tactic before I implement it into our standard. Keep in mind however that if...

The frequency bins chosen do matter and there is a science to it. Just randomly combining a multi-tone test is not a good idea IMO. I do all of the amp measurements and I am currently working with my local University to train a PHD EE student over the summer to help do these for me. My tests...

Multi-tone Distortion Testing You have to be careful when doing multi-tone distortion tests. The tests referenced from Secrets don't appear to be done with much consistency (test frequencies are different, scales are different, etc). I am thinking about revamping our FFT test to incorporate...

You're more than welcome to start your own website. Invest in test equipment and solicit manufacturers to send you products so you can measure and report on them. I'm sure you can make this all a reality in no time. Then you can create a forum so others (myself included) can come on and...

You've "alerted" the readers at least 4-5 times in this thread about your opinions. This has gone beyond that for you now. I disagree with most of your arguments and feel you are using quotes of this article out of context to push your own agenda. In any event, I updated the article for...

I agree, I prefer locking connectors. I designed audio equipment for the military so I like to have things as rugged and secure as possible...hence why I love HDMI :) RE: Distortion I don't really see the need to do multi-tone testing like that, especially into a loudspeaker load. I do spot...

Yes I think that is a fair assessment. It was definitely not like the night/day difference I heard switching from the Pass Labs / Classe amps to the Axiom digital amp. I may have a friend over to do some quicker switching for me to see if I can give a more definitive answer. The Emos and...

yes you do need to model preamp, cable, and power amp to get a more accurate picture of what is happening. The point here however is cable capacitance is important and too much acts as a LPF. The article doesn't discuss characteristic impedance or TL effects. It does talk about low...

You are free to read my prior Receiver reviews that I bench tested the preamp outs. All of the info is readily available on this site. As for the cable impedance, I have actually measured this phenomenon when designing audio communication systems for the government. In order to meet their...

THX has become quite a watered down proposition IMO. Their certification for speakers/subs is pretty easy to pass. Our "Large" bassaholic rating far exceeds anything THX does, not to mention getting our Extreme rating. As for amp testing, that again is a pretty easy thing to pass for THX...

The same could be said about jumping to conclusions and making unsubstantiated claims in a forum post to discredit this article when you have no data to back it up. 1. I have measured MANY receiver preouts that clip at 1Vrms either b/c of the limitations of the Volume controls or b/c the...
