I would rather have a company like Axiom, be able to survive and thrive on its own even if it means opening my wallet a little more.


Well said. This is a stance I find myself starting to take more and more recently.

I have some questions for anyone willing though(and please bare with me, for I'm not to up on all this technical jargon).

The ADA1500 1 channel says it's max output is 325 watts for 8 ohm and 650 watts for 4 ohm. Exactly double. So the M80v3 being a 4 ohm speaker, does that mean the 1 channel ada1500 has an available 650 watts to give to it?

The 2 channel says the same exact specs though

The 3 channel is still 325 at 8, but 500 watts at 4 ohm.

The 5 channel is 300 watts at 8 and 300 at 4 ohm.

I don't get it. Every other amp manufacturer's specs always seem to have higher numbers for "4 ohm", regardless of number of channels. It seems as the channels increase, so does lack of power.

I don't mind paying the money at all, especially if it's for axiom. But I really am hoping to be able to have an available 500 watts for every speaker in my 5 channel setup. I still have to end up with a product I need a want.

To go that route, it looks like I'd have to buy a 2 channel ada1500 and a 3 channel ada1500. That's a lot of dough

Alternatively, the Emotiva XPR-5, shipped to my door, I was quoted $2700 total, that includes all fees, taxes and duties. It says it has an available 600 watts for every one of the 5 channels, simultaneously, at 4 ohm.

How does this work? Is axiom just being much more honest with their specs? I understand the emotiva is an a/b, while the ADA is a class D...does this have anything to do with it?

I personally think the axiom is a much better product and of course isn't made in china, so I understand the raise in cost.

I'm not really trying to concentrate on the price. My questions more relate to how and why the specs work as they do.

Time to start saving hard it seems. lol

Those are good questions , maybe Andrew will stop by and educate us. This is a copy/paste from the amp page.

Understanding the Equation

Although output with eight-channels driven looks small, the fact of the matter is that the power demands from surround channels in a home theater system are much smaller than the power demands of the front left, right and center speakers. As a result, the real-world experience with these amps is lots of power available for the power-hungry front section. a seven-channel amplifier used in a home theater system acts more like a five-channel amp for power-per-channel, as shown in the chart above.



I take this to mean that since the surround channels don't contain a lot of information their power demands are low . This would leave the amp capable of supplying the front 3 channels with the 500 watts specified. No sure why anyone would need that much power anyway ,especially with how efficient the Axiom speakers are. Typical listening requires often less than 1 watt/ch. The Emo amp is definitely a beast and the specs are impressive though I cant seem to find any 3rd party tests to verify its output. I love the internet, shopping from my chair smile

The XPR 5 needs a 20A dedicated circuit, class AB is not as efficient.

I am rereading the whole thread, maybe This will help, scroll about half way down.

Well to preface...at the ear damaging levels I like my music, I definitely use more than 1 watt. I want to be able to achieve,120db...just because I can :p. After retiring my defect rotel...i just cant get it close to loud enough. Plus, I prefer extended stereo for music...i want(perhaps more than I need :p ) 500 watts available for every channel.

I'll start with a 3 channel ada and go from there tho. Who knows...maybe ill be pleased enough with that smile time to start saving.

I am glad you brought this up. I decided to read the thread from the beginning and pages 4 and 5 had the answers we both wanted.
A typical receptacle can provide only so much current, and the ADA 1500 has to work within those constraints. Even if you buy 2 amps they will have to be on separate circuits or a dedicated circuit added by your friendly electrician. .

And yeah if ya like it loud and you like power then I say get it. I am all for over indulgence lol. I like it loud too and now im goin deaf. Everything is a compromise in life.

Peace

That makes sense. Thanks. installing a new dedicated circuit isnt a problem. Its in the plans smile

Im going on 15 years of standing in front of electric guitar amps and loud music...i get hearing tests yearly through work and i'm still doing great. Itll catch up with me eventually though i'm sure lol

Lucky you smile It's only been the past 3yrs, started in my late 40's. Mostly the tinnitus, though it comes and goes. Keep us apprised of your choice. I am hoping to get a 5 ch ada-1500 , nothing says I cant add another down the road cool

That's what I thought...

Power Requirements: 115 VAC or 230 VAC +/- 10% @ 50 / 60 Hz (user selectable).
The XPR-5 requires a 20 Amp circuit and standard IEC 20 Amp outlet (which is different than a 15 Amp outlet).If you don’t have a proper circuit and outlet, we recommend you have one installed by a qualified electrician.We recommend that the XPR-5 be plugged into its own dedicated 20 Amp circuit.
From http://shop.emotiva.com/collections/amplifiers/products/xpr5

The Axiom amps are designed for standard 15 amp circuit. That probably explains the discrepancy.

EDIT: In fact, all the XPRs require a 20 amp circuit. Better add the install cost of that puppy to your total amp price! wink

I dont understand why people are making a big deal of the install of a seperate 20 amp circuit and outlet? Its quite simple and won't cost me much.

I wasnt trying to steer the conversation into a "A VS B" type of thing. I was just using that particular brand as an example to demonstrate numbers. I feel the axiom amp is a much better product quality wise. I dont understand what discrepancy you are referring to?

And Im still am hoping someone can answer my earlier questions. Why, with outlaw, rotel, emotiva, etc...do the 4 ohm specs always appear to be much more than the 8 ohm specs...while on an ada, they are the exact same as soon as you hit 5 channels?

I understand now, that fitting in the constraints of a 15amp circuit, as the number of channels increase, power per channel decreases. But still curious about my other questions. Is axiom just being more honest with their specs?

To illustrate with an,example other than emotiva..

My rotel rmb 1095 says 250 at 8 ohms,per channel and 330 at 4 ohm. So does that mean there is 330 available to each,of my 4 ohm axioms?

Sigh...i think its inevitable...im going,to have to save for 2 ada amps lol smile

In the meantime..i think I will look into repairing my rotel now that a local dealer is back.
