Power meters on amps are very slow responding and not a good indicator of how much actual power your pulling for peaks. I can tell you in my 6000ft^3 room on my Status 8T's, an amp like the XPR-1 is a real benefit when playing bass heavy music at high sustained listening levels. I've clipped...

They destroyed Vulcan not Romulus. Intro Darkness IMO was a real cheesy remake of Star Trek II. Abrams had a chance to be innovate with the new timeline. Instead, he recycled an iconic character, cheapen him into nothing more than a thug and recycled lines making them both unnatural and out...

Guys I updated Tom's preview article with some feedback I received from Yamaha. In the update is also the type of DAC's each receiver has. Stuff should be a bit more clear now since their website had some conflicting info.

Stanton, if I remember correctly, the dual center feature was nothing more than a parallel connection to a common amp. It wasn't independently configurable. It's really NOT a good idea to employ 2 centers. Almost nobody does this for good reason. Comb filtering, especially off axis will...

BTW the new RBH SX-1212/R is in fact using the SP1-4000 amplifier and RBH is rating it at the correct manufacturers 2400 watt specification. I just confirmed this with their engineer. see: Subwoofer: RBH SX-1212P/R Powered Subwoofer The amp module has a 30 amp PTC fuse so in theory it could...

We are not talking hours or even minutes here. The problem is, the same people that claim they "don't care" about power ratings are the very same ones that are over rating Power! It's funny how this is ok with subwoofer amps, but not with stand alone fullrange audio amplifiers or receivers...

No the product exists, but the honesty of power ratings varies from manufacturer to manufacturer which is clearly the point of these posts. It's one thing to post an ideal lab condition power rating and another to post an actual achievable power rating in the field. In any event, claiming the...

That appears to be a true dedicated 20A line.

Klipsch has always been a bit overly optimistic of their sensitivity ratings. We wrote an article on this very topic (though not targeting any particular manufacturer): Loudspeaker Sensitivity Specifications & Measurements Explained | Audioholics

Agreed, overrating power in power amps is a common sickness in this industry. Unfortunately PSA trying to keep up with the Jones in this case since many of their competitors are doing the very same thing. What does matter is how it measures though 3rd party verification as well as how it...

I don't want to beat a dead horse here but the amp manufacturer calls it a 4kwatt amp but their spec page actually declares it to be 2.25kwatt. It also lists the test conditions to achieve their 2.25kwatt long term power and 4kwatt short term power using burst testing on a 120V/50A line...

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...
