min. ohm load on the xpr 2?

[baranowski]

Hello.

I am thinking about trying xpr amps to drive my 802d speakers.


But....

My speakers can dip to 3 ohm. And it reads min load is 4 ohm for emotiva amps.

Am i reading the specs wrong on the amps?

Thank you
Bill

Pretty sure it's been stated before by Lonnie himself that all x and r series amps are stable @2ohms they just don't bother to publish the specs.

They will be a great match for those speakers.

Novisnick... I am sorry i do not get the joke.

Besides sending emotiva an email to their tech department is there a representative that comes on the forum that could verify?

Thanks

I'm sorry and I mean no disrespect but I've found that my set of XPR-1s would have to be pried from my cold dead hands,,,,,and then you would have to fight my wife for them, good luck with that.

the amount of shear power, authorityand dynamics that these amps bring to any system is just remarkable!!
im just trying to express myself about how great I believe these amps to be.

my journey with Emotiva amps has brought me from multichannel amps to the big dogs and every time I've found that my speakers were hiding abilities that I never thought they contained. The grew bigger, larger , more dynamic and authoritative with each upgrade in power.

to conclude my meaning is that the idea of letting my XPR-1s go never crossed my mind, and I don't think anyone that hears them would let them go either.
Peace be with you.

Nick

Well first and foremost this is an enthusiast forum not an Emotiva tech support one.
It is Sunday so maybe you may not get the answer you officially want until the working week if somebody there happens to see your particular question here.

If you don't want our answers, then I would call them on Monday.

Just trying to help.

BTW here is a review on the XPR-1 showing some power measurements that may give you a better frame of reference as to what these amps can do.

Good luck in your search!

Here is a preview of the XPR-2.

It is not that I do not want answers, I was just looking for specifics more than "it will be a great match for those speakers."

I mean no offense.

I am just looking for an answer for a question that I thought was pretty specific.

Maybe contacting the tech line tomorrow would have been a better way to go about it.

sorry

Bill

Bill,
The problem with your question is that no one can answer that but you. Yes the amp and the speakers electrically will match up. In fact emotiva uses B&W speakers for a lot of their demos. Will it be a great match ? Only you, your setup and your room acoustics can decide that. That is why Emotiva has a 30 day return policy on its equipment. Good luck with your endeavor !!!

Bill, I believe this is your best bet for an official answer. Yes some of the Emotiva staff do frequent the Lounge and will answer questions if they just happen to see your specific thread question, but the Lounge is not Emotiva's official customer service question/answer site. The Lounge is mainly for Emotiva enthusiasts and the like to discuss home theater, audio, video and what not. Many of us have lot of experience with Emotiva products and many times we can give a definite answer, but in this case since it's not on the official Emotiva website under the product listing then your best bet would be, as you've already indicated, to call their Tech Support. I'm hoping Lonnie, will see this, as he could immediately answer your question.

The XPR and XPA amps can absolutely handle a 3 ohm load with ease. The XPA-1's for instance push something like 1800 watts @ 2 ohms.
Lonnie the cheif designer confirmed this. You have no worries. I would also check out the XPA-1's. They have 60 watts of class A power. Getting two per speaker in bi amp mode gets you 120 watts of fully differential class A power per channel and about 2000 watts per speaker. It should be pretty insane!

Just a comment here, the XPR-1 will handle a 4 ohm load at 1750 watts , I'm not sure about a 2 ohm load.

I seem to remember this as well. He said they're stable at 2ohms but don't publish it because then someone will want to hook up a 2ohm speaker that will dip lower than 2ohms at certain frequencies and then wonder why their amp blinked out.

Yes, at Emofest and a few other shows Big Dan had their amps hooked up to 804 B&W speakers (if I remember right).

Actually I think your circuit breakers will give out first.

No offence taken.

Honestly, I think you'd be deaf as a post if you pulled that much current.

Here's another shot at answering your question. While your 802D's do dip down to 3 ohms or so, their nominal impedance is higher – B&W rates them at 8 but somewhere between 4 and 6 is probably more accurate. So whatever amp you choose will only have to deal with the 3 ohm impedance over a relatively narrow band. As the others have said Emo amps are 'unofficially' stable into 2 ohms as has been stated by the designer here in the Lounge. There are also many other B&W owners (including some with 802's), who use and enjoy Emotiva amps with their speakers without any problems (that they've advertised here).

I think the XPR-2 would be a excellent match for 802D's (one of my favorite speakers), only bested by a pair of XPR-1's (as Nick noted). I wouldn't hesitate, but I understand wanting to be sure, because while there is a 30 day return I personally wouldn't plan on taking advantage of it. It soon will be Monday morning and Emo will be open if you want to call and make yourself more comfortable with your purchase. Good luck - great speakers!

I have an XPA-2 driving a pair of Acoustic Research AR90s.
These speakers are a 4-way design with 5 drivers per. They have 2 x 10" woofers in parallel and dip to 3.2 ohms in several frequency spots.The amp has absolutely NO problem driving them. I feel comfortable saying the XPA-2 would drive AR9s with dual 12" woofers as easily.

I think the XPR line of amps will laugh at the load and say oh yeah.
